5000A Primary Current Injection Test System with small cart and 15KVA Power
TEST-905 primary current injection test system adopts ARM chip to
control the output process and large capacity of toroidal
transformer. It is equipped with LCD screen display current meter,
also showed primary current value, secondary current value, turn
ratio and the phase shift. Aluminum alloy body with PC panel
component the shell.
TEST-905 is mainly applied to test CT turn ratio and polarity in
the power system, the contact resistance, high voltage circuit
breaker protection test and high voltage generator test etc, which
need large current on-site or in the lab.
Besides the trip test of the complete loop to determine the integrity of the whole secondary protection circuit, other typical primary injection testing applications are:
