GE Limitamp® Medium Voltage Motor Control General A Comparison of Controller Types Full Voltage Non-Reversing The Limitamp control across-the-line (FVNR) controller is the most popular type of controller. In general, high-voltage systems have fewer power restrictions than low-voltage systems; therefore, full-voltage controllers may be applied to a greater number of applications. Full-voltage controllers provide lowest cost, simplicity, minimum maintenance and highest starting torque.
GE Limitamp® Medium Voltage Motor Control General 3. Transformer overload transformer protection from single-phasing due to blown fuses. These functions are basic only and are not intended to be comprehensive. Ground fault, differential, fault pressure, undervoltage, etc., are often required and may also be added to a given control. In addition, a transformer controller must allow for transformer inrush current and not cause a nuisance trip-out from a momentary line-voltage dip.

GE Limitamp® Medium Voltage Motor Control Controllers CR194 Vacuum Stationary & Drawout Features • Easily removable contactor — The stationary or drawout contactors can easily be withdrawn by removing easily accessible bolts. Front access to the coil and tip wear checks will substantially reduce the need to remove the contactor in normal circumstances. • 400 or 800 Ampere Contactor — Vacuum Limitamp control meets the varying needs of industry including today’s higher horsepower requirements.
GE Limitamp® Medium Voltage Motor Control Controllers B The standard contactors for industrial motor starters are closed by a single magnet and are held closed by the same magnet. This contributes to simplicity of mechanical design and increases the mechanical life of the contactor. Standard contactors may not need adjustment or mechanical repair for many years, primarily due to mechanical simplicity and sturdiness. However, preventive maintenance checks at least once per year are recommended.

GE Limitamp® Medium Voltage Motor Control Controllers B Latched contactors are interchangeable mechanically with the standard non-latched versions, both from latched to non-latched, and vice versa. However, in each case, it is necessary to change the wiring in the control circuit to the contactor coil or coils and to change the enclosure door to accommodate the manual latch release knob.

AC hipot systems, on the other hand are able to “burn-off” these anomalies, allowing the good interrupter to recover (Normal contactor load currents will also burn-off these anomalies). B If it is desired to use a DC hipot on a vacuum contactor, it is important to recognize that the results may falsely indicate a bad bottle.

GE Limitamp® Medium Voltage Motor Control Protection & Control Fuses Introduction To protect the motor branch circuit against the damaging effects of short circuits, current-limiting power fuses are used in Limitamp control. They interrupt all overcurrents of magnitude greater than intended for contactor interruption. On full fault, these fuses start limiting current within the first 1/4 cycle and interrupt within the first 1/2 cycle.
GE Limitamp® Medium Voltage Motor Control Protection & Control surge wave front to keep the turn-to-turn voltage stress in the machine winding to a minimum. F Surge capacitors and arresters should be installed as close to the machine terminals as possible. Capacitors and arresters may require a 22-inch wide auxiliary enclosure if installed in the controller. Overload Relays Figure F.2 Blown fuse indicator With this feature, fuses are always bolted in place for correct orientation and alignment.
GE Limitamp® Medium Voltage Motor Control Protection & Control hermetically sealed air-conditioning motors, and is well suited as a stall-protection relay. Multifunction Solid-State Relays Large motors on vital drives need accurate protection against overloads, phase unbalance or ground faults. Multifunction solid-state relays are available from GE that offer total motor protection in one compact package.
GE Limitamp® Medium Voltage Motor Control Protection & Control F The cost of this type of relaying is justified by the size of the investment to be protected. Large motors (usually above 1500 hp) that are expensive to repair or replace often employ differential relays. Specifically, differential relays accomplish the following: 1. Provide for power interruption to a motor in the event of a phase-to-phase insulation failure in the motor windings. 2.
GE Limitamp® Medium Voltage Motor Control Protection & Control Undervoltage Protection NEMA defines undervoltage protection as a device whose principal objective is to prevent automatic restarting of equipment. Instantaneous undervoltage protection is inherent to the standard 3-wire control circuits, since the contactor will drop out and stay out on loss of voltage.
GE Limitamp® Medium Voltage Motor Control Protection & Control F On-Line Field Adjustment The manual potentiometer is normally mounted on the door and allows an operator to adjust the motor field current while the motor is running. This provides the convenience over the SFC type exciter of not having to shut down the motor and physically move cables between several taps on the exciter transformer.
GE Limitamp® Medium Voltage Motor Control Protection & Control circuit after a definite elapsed time on either energization or de-energization. Incomplete-Sequence Relay An incomplete-sequence relay is used to shut down the motor (squirrel-cage induction or synchronous) on reducedvoltage starting if the control fails to transfer to full voltage. This standard feature protects the autotransformer from energization longer than rated time. The relay can be furnished for other sequencing functions also.
GE Limitamp® Medium Voltage Motor Control Protection & Control F Elapsed Time Meter An elapsed time meter is used to indicate hours of operation or shutdown time of a particular motor or drive for the purpose of production records, maintenance scheduling, or engineering records. Transducers Transducers are used to transmit electrical properties to remote devices, while maintaining a high accuracy when the cabling distance or resistance may be high. The standard output is 4 - 20 mA DC.
