Test Signal Description
AC
(sinusoidal)
The waveform is a sinewave starting at zero crossing, polarity
determined by phase selection (0
q
phase starts with low to high zero
crossing, 180
q
phase starts with high to low zero crossing). The
magnitude of the test current is I
'
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 0.7 x I
ǻ
n (rms) x Multiplier for all
tests where the multiplier is x0.5 (x1/2). The magnitude of the test
current is 2.0 x I
ǻ
n (rms) x Multiplier for all tests where both the
multiplier is x1 and I
ǻ
n = 0.01A. The magnitude of the test current is
1.4 x I
ǻ
n (rms) x Multiplier for all tests for all other settings
.
B (DC)
This is a smooth DC current according to EN61557-6 Annex A
