Powerful short-circuit current will cause overheating and burn the winding insulation

Large transformers in an increasing number of grid operation. These transformers will inevitably be a variety of short-circuit accident threat, in the event of a short circuit, short-circuit current will cause a strong overheat and burn out the winding insulation. Meanwhile, the huge electric power will cause winding deformation, mcb circuit breaker expansion into inter-turn, short circuit between cake and even the body collapse out. Therefore, the power sector and the majority of users of the transformer  Circuit breaker  higher reliability requirements. Requires adapter have adequate dynamic stability and thermal stability, in order to ensure safe operation of the transformer. In order to check the transformer dynamic and thermal stability, have asked the transformer short-circuit test, to test its mechanical strength.
