Large Voltage and Frequency Ranges
A broad-range measuring device allows for use of the test instru-
ment in all alternating and 3-phase electrical systems with volt-
ages from 65 to 500 V and frequencies of 16 to 400 Hz.
Loop and Line Impedance Measurement
Measurement of loop and line impedance can be performed in
the 65 to 500 V range. Conversion to short-circuit current is
based on the respective nominal line voltage, insofar as the mea-
sured line voltage is within the specified range. PROFITEST MAS-
TER measuring error is also taken into account for conversion.
Outside of this range, short-circuit current is calculated on the basis of
momentary line voltage and measured impedance.
Measurement of Insulation Resistance Using Nominal Voltage, with Vari-
able or Rising Test Voltage
Insulation resistance is usually measured with a nominal voltages
of 500, 250 or 100 V. A test voltage which deviates from nominal
voltage, and lies within a range of
20/50
to 1000 V, can be
selected for measurements at sensitive components, as well as
systems with voltage limiting devices.
Measurement can be performed with a constantly rising test volt-
age in order to detect weak points in the insulation and determine
tripping voltage for voltage limiting devices.
Voltage at the device under test and any triggering/breakdown
voltage appear at the test instrument’s display.
Standing-Surface Insulation Measurement
Standing-surface insulation measurement is performed with
momentary line frequency and line voltage.
Low-Resistance Measurement
Bonding conductor resistance and protective conductor resis-
tance can be measured with a test current of 200 mA DC, auto-
matic polarity reversal of the test voltage and selectable direction
of current flow. If the adjustable limit value is exceeded, an LED
lights up.
Earthing Resistance Measurement
In addition to measurement of the overall resistance of an earthing
system, selective measurement of the earthing resistance of an
individual earth electrode is also possible, without having to dis-
connect it from the earthing system. A current clamp sensor avail-
able as an accessory is utilized to this end.
Furthermore, the PROFITEST MPRO and the PROFITEST MXTRA
allow for battery powered earthing resistance measurements:
3/4-
pole and earth loop resistance measurements.
Universal Connector System
The interchangeable plug inserts and 2-pole plug-in adapter –
which can be expanded to 3-poles for phase sequence testing –
allows for use of the test instrument all over the world.
