Application Series BH-0.66 typeⅠ and typeⅡcurrent transformer is the busbar current transformer suitable for AC 50Hz 0.66KV and below circuit to measure current and electric energy and to provide relaying protection. Type designation
Notes:TypeⅠ(square circuit hole)capable of passing through either the cable or the bus bar is generally used tor the purpose of monitoring. Type Ⅱ(horizontal square hole)capable of passing through 1-3 bus bar(S)isgenerally used for the purpose of monitoring. Type Ⅲ(Vertical square hole)capable of passing through 1~3 bus bar(S) is generally used for the purpose of monitoring. is also intended to measure the electric energy of power supply system(Class0.2).It can still be used at larger secondary impedance and act as the Zero-sequence current transformer.
