5.4 Testing RCDs
Various test and measurements are required for verification of RCD(s) in RCD protected
installations. Measurements are based on the EN 61557-6 standard.
The following measurements and tests (sub-functions) can be performed:
‰
Contact voltage,
‰
Trip-out time,
‰
Trip-out current,
‰
RCD autotest.
See chapter
4.1 Function selection for instructions on
key functionality.

The instrument is intended for testing of
G eneral (non-delayed) and S elective (time-
delayed) RCDs, which are suited for:
‰
Alternating residual current (AC type, marked with symbol),
‰
Pulsating residual current (A type, marked with symbol).
‰
Pulsating residual current (A type, marked with symbol).
‰
Model TESTBOY TV 450 (Type B): DC residual current (B type, marked with
symbol).
Time delayed RCDs have delayed response characteristics. As the contact voltage pre-
test or other RCD tests influence the time delayed RCD it takes a certain period to
recover into normal state. Therefore a time delay of 30 s is inserted before performing
trip-out test by default.
