Combined T100s Test of 252?kV Common Drive Circuit Breaker for GIS
The standard GB/T 1984-2014 for AC high-voltage circuit breakers specifies the combined testing of neutral point effective and non effective grounding systems,but does not involve 60Hz operating conditions.There is a description of 50/60Hz combined testing for IEC 62271-100 in the corresponding STL guidelines,but domestic manufacturers usually conduct separate tests for 50/60Hz.The article introduces the multi parameter merging test of the 252kV circuit breaker T100s,provides a testing method that can perform multi parameter testing,points out the advantages and disadvantages of multi parameter merging test,and provides effective reference for other similar multi parameter merging tests in the future.
