Testing of Residual-Current
Protective Devices (RCCBs)
• Measurement of contact voltage without tripping the RCCB
Contact voltage with reference to nominal residual current
is measured with 1/3 of nominal residual current.
• Trip test with nominal residual current, measurement of
time to trip
Special Testing for Systems and RCCBs
• Testing of systems and RCCBs
with rising residual current and display of trip current,
as well as contact voltage at the moment tripping occurs
• Testing of RCCBs (10 and 30 mA) with 5 • IΔN
• Testing of RCCBs
which are suitable for pulsating DC fault current,
testing is conducted with positive or negative half-waves
• Testing of RCCBs with adjustable residual current
for the determination of contact voltage and trip current

Large Voltage and Frequency
Range
An extended-range measuring system allows
for use of the test instrument for all AC and three-phase systems
with voltages ranging from 60 to 500 V, and frequencies from 15 to
70 Hz.
Loop and System Impedance Measurement
Measurement of loop and system impedance can be performed within a
range of 65 to 250 V. Conversion to short-circuit current is based
upon respective line voltage, as long as the measured
line voltage is within the prescribed range. Short-circuit current
is calculated from actual line voltage and measured impedance for
line voltages outside of this range.
With a test current of 15 mA the loop impedance can also be
determined after RCCBs with a nominal residual current of at least
30 mA without the RCCB being tripped.
Insulation Resistance Measurement with Nominal Voltage and
Variable or Rising Test Voltage
Insulation resistance is usually measured with the nominal voltages
500 V, 250 V or 100 V. For measurements at sensitive components, as
well as within systems with voltage limiting devices,
22 different test voltages ranging from 20 to 500 V can be selected,
which deviate from, and are generally lower than nominal voltage.
Measurements can be performed with continuously rising voltage for
the detection of weak points in insulation, as well as for the
determination of response voltages for voltage limiting devices.
Voltage at the device under test, any detected response or breakdown
voltage, as well as insulation resistance appear at the instrument’s
display, and an LED indicates violation of an (adjustable)
limit value.
Low-Resistance Measurements
Bonding conductor resistance and protective conductor resistance can
be measured with a measuring current of ≥ 200 mA DC, automatic
measuring voltage polarity reversal and selectable conduction
direction. Violation of an (adjustable) limit value is signaled with
an LED.
Standing-Surface Insulation Measurement
Measurement of standing-surface insulation is performed with actual
line frequency and line voltage.
