Sine wave in the time domain and frequency domain equivalent circuit method equivalent circuit Combination

It is necessary to use a start of pumping with a large capacity, in the normal operation pumping unit has a small capacity, the capacity can be adjusted for the modulation capacity  air circuit breaker . The study load  Circuit breaker  of the transformer principle is the use of transformer capacity and loss of the relationship between the transformer losses and operating costs of the relationship between, from the "road" point of view, the use of equivalent sine wave in the time domain, etc.  mcb circuit breaker  circuit method and frequency-domain equivalent circuit combination form of time domain - frequency domain method is applied to the transformer characteristics of deduced load transfer capacity of the transformer magnetic circuit model and the model.
