Test Signals
RCD Type Test Signal Description
AC
(sinusoidal)
The waveform is a sinewave starting at zero crossing, polarity
determined by phase selection (0 ° phase starts with low to high zero
crossing, 180 ° phase starts with high to low zero crossing). The
magnitude of the test current is I
Δ
n x Multiplier for all tests.
A
(half wave)
The waveform is a half wave rectified sinewave starting at zero,
polarity determined by phase selection (0 ° phase starts with low to
high zero crossing, 180 ° phase starts with high to low zero crossing).
The magnitude of the test current is 2.0 x I
Δ
n (rms) x Multiplier for all
tests for I
Δ
n = 0.01A. The magnitude of the test current is 1.4 x I
Δ
n
(rms) x Multiplier for all tests for all other I
Δ
n ratings.
B (DC) This is a smooth dc current according to EN61557-6 Annex A
