A brief introduction to surge protection Is surge protection worthwhile? Is surge protection worthwhile? A You can rely on luck or take precautions The priority you give to surge protection depends on your willingness to take risks! Perhaps you think ”it’ll never happen to me”. You won‘t have lost anything, but you will also have gained little, if nothing at all, and you run the risk of a surge overvoltage at any time.
A brief introduction to surge protection Is surge protection worthwhile? Disaster from inside your premises Wherever electricity is used, it must also be switched on and off. The physical processes involved in a switching operation cause many surge overvoltages than those from the sky. Added to this are overvoltages caused by electrostatic discharges or faulty switching operations.

Lightning and surge protection for control and instrumentation signals SU RG EP RO TEC TI 0 1 2 3 4 5 MSR breakdowns or malfunctions can lead to exorbitant costs. As the standards covering low control voltages do not specify many parameters, the use of surge protection, apart from lightning protection zoning concepts, has to be classified according to type of signal, application circuit and the anticipated interference voltage phenomena.
Essential information for users can be found in the IEC 61643-22 standard (application standard for measurement and control signals) and in the IEC 62305-4 standard (application standard for installing internal lightning protection). It is important to determine which protection category is required. There are divisions for D1 (lightning protection), C2 (surge protection / overvoltage protection) and C1 (end device protection). These categories or classes are specified for the following products.
Lightning and surge protection for control and instrumentation signals VARITECTOR SPC VARITECTOR SPC Pluggable lightning and surge protection for measurement and control circuits Pluggable lightning and surge protection for 2 analogue signals or 4 binary signals in measurement/control circuits – with integrated error detection and alert functions in only 17.8 mm width. B Our pluggable VARITECTOR SPC surge protection is characterised by highest protective functions with compact dimensions.
Monitoring function Status display and message function: the protective function can be evaluated externally. Quick identification Colour-coded marking: simple identification of the different voltage levels in the switching cabinet.
Lightning and surge protection for control and instrumentation signals VARITECTOR SPC B VARITECTOR SPC Pluggable surge protection for the measurement and control industry VARITECTOR SPC Weidmüller's VARITECTOR SPC pluggable surge protection is remarkable for its combination of extremely high protective functionality and compact dimensions. It is suited for use in measurement and control circuits. The size is made possible by the seletion of INSTA dimensions, with a width of 17.8 mm (1TE).
Lightning and surge protection for control and instrumentation signals VARITECTOR SPC transfer the alert function to a 2-pole screw/plug-in connection in the bases and to the VSPC CONTROL UNIT. VSPC 1CL The VSPC 1CL is a two-stage protective combination with a gas discharge tube and a suppressor diode located between the current paths. This VSPC 1CL limits the surge voltage within one analogue signal circuit (such as for current loops).
Lightning and surge protection for control and instrumentation signals VARITECTOR SPC Applications B VSPC TAZ VSPC MOV The VSPC MOV 2CH and TAZ 2CH offer one-stage protection with a varistor (MOV) or suppressor diode (TAZ or TVS) between the current paths. This makes it possible to protect a no-voltage (floating) signal circuit. Two binary signal circuits can also be protected if terminals 1 and 7 are assigned to GND / PE. These VSPC pluggable components are inserted into the base (VSPC BASE 2/4CH).
Lightning and surge protection for control and instrumentation signals VARITECTOR SPC Test possibility / V-TEST Because the modules are pluggable, it is possible to test the VSPC visually or by using a V-TEST testing device. The VSPC can be easily tested; the user needs only to insert the VSPC pluggable component into the V-TEST. The result is then shown on the display. The VSPC R modules also feature an internal monitoring function for the arrester. An error is the displayed at the defective module.

Lightning and surge protection for control and instrumentation signals Earthing for shielded cables B Differences between earthing and shielding The terms “earthing” and “shielding” are classified according to their relation to human safety or facility safety. The earth is installed primarily to protect human life and for this reason is referred to as the protective earth conductor. On the other hand, shielding is used to ensure that the electrical system functions properly.
Lightning and surge protection for control and instrumentation signals Earthing for shielded cables Earthing for shielded cables Electrical and electronic systems should be designed and installed so that they are essentially protected against electrical interference, so that they also function reliably in the event of transient interference voltages. Electrical interference is introduced into circuits in many different ways. The most frequent cause is inductive interference effects.
Lightning and surge protection for control and instrumentation signals Earthing for shielded cables B Shielding In practice, the shield is often twisted and connected to a terminal point. There is very high attenuation (voltage drop) on these connections, especially for high-frequency interference. Therefore this type of shielding should not be used, even for short cable lengths. The cable shield is practically negated and can, at best, be helpful for lowfrequency interference.
Lightning and surge protection for control and instrumentation signals Earthing for shielded cables Effective shielding It is important to remember that the shielding should not be connected to the earth of the module connected, but rather to the protective earth (PE). In the case of modules mounted in an earthed, metal housing, the shielding must be connected to this housing. If an earthed housing is not available, the shielding must be connected to a separate earth.
Lightning and surge protection for control and instrumentation signals Installation advice for instrumentation and control engineering B Installation advice for instrumentation and control engineering The supply and earth lines to protective modules should be kept short in order to achieve optimum protection for equipment. The fuses for the protective modules should be chosen depending on the rated current as well as on the type of line and its route.

Surge protection for photovoltaic systems Photovoltaic application example Surge protection prevents damage Photovoltaic (PV) facilities for exploiting renewable energy are at great risk from lightning discharges because of their exposed location and large surface area. Damage to individual segments or the failure of the entire installation can be the consequence. Lightning currents and surge voltages often cause damage to inverters and photovoltaic modules.
Surge protection for photovoltaic systems Photovoltaic application example F Standards and requirements The current standards and directives for overvoltage protection must always be taken into account in the design and installation of any photovoltaic system.
Surge protection for photovoltaic systems Photovoltaic application example Superior surge protection from Weidmüller Our surge protection modules in Class I and Class II (B and C arresters) ensure voltage occurrences are quickly limited and that the current is safety discharged. This allows you to avoid expensive damages or the potential for complete power failure in your photovoltaic facility.
Surge protection for photovoltaic systems Photovoltaic application example solar generator (to protect the solar modules) as well as at the DC input of the inverter (to protect the inverter). SPDs should be installed close to the PV generator as well as close to the inverter as soon as the length of cable required between the PV generator and the inverter extends beyond 10 meters (Figure 2).
Surge protection for photovoltaic systems Photovoltaic application example To summarise: protective circuitry with absolutely zero leakage current is in place and an accidental activation of the disconnecting mechanism is prevented. In the scenario described above, the spread of fire is also effectively prevented. And at the same time, any influence from an insulation monitoring device is also avoided. So if an insulation malfunction occurs, there are always two varistors still available in the series.
Ready-to-fit solutions Surge protection for photovoltaic systems Photovoltaic application example VPU II 3 1000 V DC PV To ensure on-site installation is as straightforward as possible Weidmüller offers ready-to-fit solutions to protect the DC and AC sides of inverters.

Surge protection for photovoltaic systems Photovoltaic application example Modular use of our surge protection components If a lightning protection system is already present on the building, this must be at the highest point of the entire system. All modules and cables of the photovoltaic installation must be installed below the air terminations. Separation distances of at least 0.5 m to 1 m must be maintained (depending on risk analysis from IEC 62305-2).

The basics of lightning and surge protection Prevention is better than cure For energy protection, these are IEC 61643-1 and IEC 61643-11. For protection of measurement and control systems, IEC 61643-21 is relevant. These standards provide the rules which are globally valid for all manufacturers of surge protection components. The standards also provide helpful support for users.
What are overvoltages? Surges are extremely high voltages that damage or even completely destroy insulation and hence impair or completely disrupt the function of electrical and electronic components of all kinds. Every electrical component is provided with insulation to isolate the electrical voltage from earth or other voltagecarrying parts. The insulation strength is dependent on the rated voltage and the type of electrical component, as stipulated by the IEC/VDE regulations.
How do overvoltages occur? The basics of lightning and surge protection How do overvoltages occur? Conductive coupling Surges are primarily caused by: • Transient switching operations • Lightning due to atmospheric discharges • Electrostatic discharges • Faulty switching operations i1 i2 Lightning Zg Bolts of lightning comprise extremely high currents. They can cause a large voltage drop and a large rise in potential, even in well-earthed buildings or systems, despite low earthing resistances.
The basics of lightning and surge protection How do overvoltages occur? Radiation coupling E /H Electromagnetic wave fields (E/H field), that also ensue during lightning (distant field condition, E/H field vectors perpendicular to each other), affect conductor structures in such a way that coupled overvoltages must be expected even without direct lightning strikes. Permanent wave fields from strong transmitters are also able to cause coupled interference voltages in lines and circuits.
The basics of lightning and surge protection How do overvoltages occur? SU RG EP RO TEC TI ON Transverse voltage UQ (normal-mode voltage) Longitudinal voltage UL (common-mode voltage) A coupled transient interference voltage between an active conductor and the earth potential. As a rule, the longitudinal voltage is higher than the transverse voltage (transverse voltage is lower owing to cable shielding and twisting).
How do we achieve surge protection? We have to consider surge protection from two points of view: • General protective measures during the planning and construction of buildings and electrical installations. • Special protective measures realised by the installation of additional surge protection components.
Surge protection concept ON A fundamental requirement for effective surge protection is the presence of properly functioning equipotential bonding to DIN VDE 0100 part 540 in a series, or better still, star or grid arrangement.
The basics of lightning and surge protection Surge protection concept If a lightning protection system has been installed, or the power supply is via overhead lines, or buildings or plants are spread over a wide area and individual buildings are sited on elevated ground or open areas, high-capacity Type I arresters should always be employed. Type II arresters based on varistors are normally installed in the subdistribution board before the residual-current circuitbreakers. 2.
Classification and protective zones The requirements placed on surge protection and the necessary tests for surge protection components are stipulated by national and international standards. A product can only be considered safe after the product has been fully tested.
The basics of lightning and surge protection Lightning protection levels Schutzklasse Lightning protection levels (LPL) I 200 kA 100 kA 100 kA 150 kA 75 kA 75 kA 100 kA 50 kA PAS 50 kA Lightning protection level II Lightning protection level II covers a pulse of 150 kA. This pertains to external lightning protection facilities. Half of this pulse is conducted to the earth and the other half is conducted to that section of the facility that is conductive.

The basics of lightning and surge protection Network forms Five-conductor systems: The neutral point of the supply source is earthed (N and PE). Both conductors must be laid separately and insulated from the incoming supply onwards. In these systems the PE (protective earth conductor ) does not carry any operating current but instead only discharge currents. TN-S systems TT systems Neutral conductor and protective earth conductor are separated throughout the network.
The basics of lightning and surge protection 3+1 circuit: universal solution Surge protection with 3+1 circuitry in consumer loads with TT power systems 3+1 does not always equal 4! At least not in the case of protective circuits with arresters in a TT system. In a TT system the supply is via the three phase conductors L1, L2 and L3 and the neutral conductor N, i.e. without an additional integral PE conductor.
The sparkover gap isolates the three varistors electrically from the PE so that leakage currents through the varistors cannot cause voltage increases at the PE. The residualcurrent circuit-breaker behind the 3+1 circuit then provides reliable protection against hazardous touch voltages in all situations. In terms of its relevance for safety aspects, the 3+1 circuit described in VDE 0100 part 534 (section 534.2.2) can therefore be regarded as a solution for surge protection in TT systems.

The basics of lightning and surge protection General installation advice Behaviour of NH fuses for lightning surge current (10/350 µs) It is important to understand that the question is not how small the SPD fusing should be; rather the maximum backup fuse that should be used, as the capacity of the small fuses to carry lightning current is very limited. Unrestricted SPD protection is only available when the installation accommodates the maximum value.
Installation instructions for Weidmüller‘s VPU I, VPU-II and VPU-III lightning/surge protection in power grids Surge protection should only be installed by trained personnel. Please follow all local regulations concerning connection methods during the installation.
The basics of lightning and surge protection Surge protection installation instructions 3.1 Connection to the phase conductor and the neutral wire When connecting cables to the VPU I/VPU II arresters, normally the same wire cross-section is used both for the phase conductors (L1, L2, L3) and the neutral wire (N). If you need to reduce the cross-sections, then a protective device (e.g. a main port fuse) should be used to protect the connecting cables from short circuits.
5.1 Replacements 8 Application When an arrester has a red window (as described by point 5) or a red LED, then the arrester should be replaced by a qualified electrician. The individual Type I-I/II arresters are pluggable and coded for voltage. For the insulation resistance test, the SPD must be disconnected from the facility during the duration of the measurement (e.g. by pulling out the upper sections) or the arresters are disconnected from the power network.
The basics of lightning and surge protection Surge protection installation instructions VDE 0100-534 now states that there should be a gap of ≤ 0.5 m between the SPD in the vicinity of the installation location and the direct connection to N or PE. IEC 60364-5-534 specifies that the earth must be established from the SPD to the equipotential bonding rail or to PE – whichever is the shortest connection. Both cables are specified in the VDE.

The basics of lightning and surge protection Components for Surge protection Components for Surge protection Surge protection devices (SPDs) There is no ideal component that can fulfil all the technical requirements of surge protection equally effectively. Instead, we use a variety of components with different physical methods of operation that complement each other; these possess distinct protective effects.
2. Varistors / MOV The basics of lightning and surge protection Components for Surge protection 3. Suppression diodes / TAZ U U t U t The varistors used with surge protection (MOV-Metal Oxide Varistors) have resistance which depends on the voltage. This is implemented with metal-oxide (zinc-oxide) discs. There is a low-ohm resistance in the range above the rated voltage. The surge voltage is limited since a current flows through the varistor. The varistor works bi-directionally.
The basics of lightning and surge protection Components for Surge protection 4. Combination circuits Combining the components described above results in surge protection products that can match individual requirements. If a voltage pulse reaches the input of such a combination circuit, then the gas discharge tube is fired and discharges high current. The residual pulse is attenuated by a downstream inductance and subsequently received and limited by the varistor and/or suppression diode.
Test criteria Classification formerly VDE IEC 0675 Coarse Bprotection arrester The classification is based on the experience that “B arresters” can become overloaded in extreme situations, and also on more recent investigations into lightning discharges. This resulted in the standardised 10/350 µs current curves for the testing of “Type I” arresters. The test parameters lie between 12,5 and 25 kA Ipeak or Iimp.
The basics of lightning and surge protection Electromagnetic compatibility Electromagnetic compatibility EMC – electromagnetic compatibility – means the trouble-free interaction between electrical and electronic systems and devices without mutual interference. In this respect, any electrical item can act both as transmitter (source of interference) and r eceiver (potentially susceptible device) simultaneously.
The basics of lightning and surge protection Electromagnetic compatibility These last two functional interferences result in stoppages for entire production facilities and cause high breakdown costs.
The basics of lightning and surge protection Questions and answers concerning surge protection FAQ list When do I need a Type I arrester, when a Type II arrester? Why are there 3- and 4-pole versions? In a lightning protection system set up on a building, the Type I arrester achieves the lightning protection equipotential bonding for the supply voltage. The Type I arrester is used when higher pulses are expected and is installed in the vicinity of the incoming supply.
What does this have to do with the 3+1 circuitry? If Type II arresters are now being led to a neutral conductor instead of a local earth in a TT system, then, for an arrester that has become low ohm, only the wire resistance of the neutral wire limits the incipient follow-on current. Immediately after the fault, this is isolated from the spur line fuses or from the main fuses that are carrying the operating current.
The basics of lightning and surge protection Questions and answers concerning surge protection When should I use CL or SL circuits with surge protection components for measurement and control systems? The difference between the switching in the CL (current loop) and SL (symmetrical loop) is the integration of the suppressor diodes. The CL circuit has a diode between the lines. This system is used for current loops and offers direct protection at the input or output of the analogue sensor.

Fuse, back-up fuse A back-up fuse is required if the upstream fuse F1 is greater than the maximum value specified by the manufacturer. Remember to select the largest nominal value in keeping with the ratio F1 to F2 (back-up fuse before SPD) = 1 : 1.6.

Various error states inside and outside the low voltage consumer facility of a building can occur to cause TOVs.
