Low Voltage Simulation Device for Circuit of the Synthetic Test
new test circuit and new test circuit parameters must have been simulated before testing in order to verify its correctness. In this paper
according to the principle of "capacitive current injection method"
a low voltage simulation device is designed for the synthetic test circuit for circuit breaker. The technical scheme and hardware principle of the device are discussed. Besides
several important factors that influence low voltage simulation device’s measuring waveform are analyzed
several notes and calibration methods are given. The prototype of the device is built and the expected performance is verified by experiment. And the practical application purposes has been reached.
