Product overview

When measuring the high current of alternating current, BHP2 series current transformers need to be converted to a relatively uniform current for the convenience of secondary instrument measurement (the secondary rating of current transformers is set as 5A or 1A in China). Current transformer in the process of short circuit transition can correct the primary current, the relay protection of right action plays a decisive role, protective current transformer (TA) mainly cooperate with relay protection devices, such as short circuit occurred in line failure, provide signals to cut off the fault circuit to relay device, protect the safety of the power system. Primary measuring range 200-6300A, secondary output 5A, 1A, main accuracy levels: 5P10, 10P10, 10P20, 5P20, etc. Collect low voltage overload and short circuit signals, and use with motor protection unit.
