therefore, the connection between neutral point of the distribution system and earth
should be checked before testing.
●
If leakage currents flow in the circuit following the RCD, it may influence the
measurements.
●
The potential fields of other earthing installations may influence the measurement.
●
Special conditions of RCDs of a particular design, for example S- type, should be
taken into consideration.
●
The earth electrode resistance of a measuring circuit with a probe shall not exceed
table1.
●
Equipment following the RCD, e.g. capacitors or rotating machinery, may cause a
significant lengthening of the measured trip time.
