Abstract :
The zero sequence current transformer is one of the key component of permanent magnetism leakage circuit protection breaker and release relay. A C8051F120 microcontroller is used as the controller of performance test system of an intelligent zero sequence current transformers. We analysis the operating and test principle of zero sequence current transformer, hardware composition and software program. The results show that the test system can quickly and accurately test the performance index and characteristics curve of magnetic core of zero sequence current transformers.
