Abstract
4 stand-alone capacity of 80 MW vertical mixed-flow water turbine generators are installed in a hydropower station. The generator and transformer unit wiring with generator circuit breaker, unit 2 sets of 100 MVA 220 kV capacity double winding transformer and 2 sets of 100 MVA 220 kV three winding transformer. The current transformer is an electrical equipment for transformation of the current transformer usingprinciple, its main role is to transform high voltage small current and low voltage high current into low voltage small current, so it is widely used in electric power system. This paper describes the basic principle of the current transformer and the test principle of two circuit current transformer on-site and the matters needing attention.关键词
