Current Transformer
4 - 3
CT Ratio (and Burden)
Testing Ratio, Polarity (and Burden) with Injection to
Current Input
Use the
CTRatio
test card to measure a current transformer’s ratio and burden
with injection on the CT’s primary side with up to 800 A from the
800A AC
output
or up to 2000 A using the
CP CB2
current booster connected to the "
EXT.
BOOSTER
" output.
It measures amplitude and phase angle of the current (at
IAC
) and voltage
(at
V1AC
) on the transformer’s secondary side, and calculates the actual ratio
and the deviation from the nominal ratio.
