Optimization of Leakage Calculation in RCP System of PWR

This article mainly describes the grounding way in medium-voltage system,on the same circuit with multi-cable,how to selet zero-sequence current transformers and analysis to connecting way of their secondary coils,so that we selet the best wiring way.

Development of intelligent CAD system software for primary circuit in transformer substations;

It was pointed out that it was the larger contact résistance in primary circuit of a 200 MW turbine generator, which produced a larger unbalance voltage at open triangle of the potential transformer secondary side, that caused the protection malfunction among turn-to-turn, and some suggestions of solving these problems available were presented for .
