At the end of 2021, we received the order contract for 10kV switchgear and its auxiliary equipment of Vietnam PAHA Power Station.

The main function of the isolation transformer is to completely insulate the electrical light on the secondary side, and the loop is isolated. In addition, the high frequency loss of its core is used to suppress high frequency clutter incoming control circuits.

The transformer iron heart magnetic flux is related to the exerted voltage. In the current, the excitation current does not increase as the load increases. Although the load is not saturated, the resistance loss of the coil will increase, exceeding the rated capacity due to the heat generated by the......
