摘要
Abstract
This article puts forward the design proposal of the Rogowski passive prop electronic current transformers to aim at some disadvantages existing in the Rogowski active prop electronic current transformers implements like destroyed easily, maintained troublesomely. Collection unit located on high-pressure side is moved to low-pressure side in transformer foundation, sensing head and electric circuit are connected by special shielded cable, instation cable are used to solve power supply of electric circuit, the 110kV Rogowski passive prop electronic current transformers according to this proposal has passed type tests by SGC electrical science institute, and also test runs in certain substation. The results indicates that this program has engineering practicability.关键词
