The concept of unit magnetization capacity of silicon steel sheet. What does the letter of transformer mean?
The loss of the transformer is an important performance parameter of the transformer. On the one hand, it shows the efficiency of the transformer in operation, and on the other hand, the performance of the transformer in the design and manufacture meets the requirements. Transformer no-load loss and no-load current measurement, load loss and short-circuit impedance measurement are all routine tests of transformers.
The secondary circuit of the transformer is that all secondary units of the transformer do not receive any load (except for monitoring instruments).
The no-load test of transformer is to measure the no-load loss and no-load current of transformer by applying rated voltage from any coil of transformer and other coils open. With it and the percentage of the no-load current rated current, i.e., the no-load test is to measure the transformer no-load loss and no-load current; calculation and verification of design of transformer core manufacturing process meets the requirements and standards for technical requirements; check the transformer iron heart defects, such as local overheating, poor insulation.
