Abstract:
Abstract:The circuit connections of potential transformer used by the three active transmitters at the outlet of E class gas turbine generator were the same set of coils voltage,and they were also lack of redundancy.Once primary or secondary circuit break happened in the potential transformer,it might lead to large fluctuations on output power signal values of the three active transmitters simultaneously.Furthermore,tripping accidents might occur.After a deep analysis and investigation of the above problem,the signal circuit and logic were improved.As a result,the lack of redundancy problem was solved,and the safety and reliability of equipment operation were improved as well.
