Discussion on the Problems in Characteristic Test of High Voltage Breakers in Transformer Substation
With regard to the problems in characteristic test of high voltage breakers in a transformer substation
this paper analyzes the design of testing device and whether the control power supply for breaker is necessary.The DC-earthing problem which may happen in testing process and the improvement in design of the testing devices for mechanical and low voltage characteristics of breakers are discussed.Moreover
the meaning of time-stroke curve is also analyzed.
