High-low
Voltage Current Transformer Ratio Tester is a new
electric checking
device for high voltage measurement users. It is
able to test the ratio and po-
larity of measurement device electric transformer
with voltage of 10KV or less
under the condition of not stop electricity and
not change wire connection. So
that it is able to effectively avoid high voltage
measurement users changing t-
he current transformer or changing its nameplate
or changing polarity of second
wire with the purpose to use electricity illegally.
