Analysis of Voltage Regulation Methods and Principles of UHV Transformers Open
The autotransformer voltage regulation is divided into two types: on-load voltage regulation and non-excitation voltage regulation. According to the position, it can be divided into medium voltage side line end voltage regulation, neutral …
Working principle and testing technology of circuit breaker closing resistor for 1100kV GIS Open
The closing resistor can suppress the operation overvoltage and release the energy caused by the overvoltage generated by the power system when switching the line. It is widely used in the ultra-high voltage system AC system. Due to the co…
