Special Functions
Tripping Test for Type B, AC/DC Sensitive RCDs with Rising DC
Residual Current and Measurement of Tripping Current
With the selector
switch in the I
F
position, slowly
rising current
flows via N and
PE. The momen-
tary measured
current value is
continuously dis-
played. When the
RCCB is tripped,
the last mea-
sured current value is displayed. A greatly reduced rate of increase is
used for delayed RCCBs (type
).
Tripping Test for Type B, AC/DC Sensitive RCDs with Constant DC
Residual Current and Measurement of Tripping Time
With the selector switch set to the respective nominal residual
current, twice the selected nominal current flows via N and PE.
Time to trip is measured for the RCCB and displayed.
Loop Resistance Measurement with Suppression of RCD Tripping
The test instruments make it possible to measure loop impedance
in TN systems with type A, F
and AC RCCBs (10, 30, 100,
300, 500 mA nominal residual current).
The respective test
instrument gener-
ates a DC residual
current to this end,
which saturates the
RCCB’s magnetic
circuit.
The test instrument
then superimposes
a measuring current
which only demon-
strates half-waves
of like polarity. The
RCCB is no longer
capable of detecting this measuring current, and is consequently
not tripped during measurement.
Voltage Drop Measurement (at Z
LN
) – U Function
According to DIN VDE 100-600,
voltage drop from the intersection
of the distribution network and
the consumer system to the point
of connection of an electrical
power consumer (electrical outlet
or device connector terminals)
should not exceed 4% of nominal
line voltage.
Voltage drop calculation:
