另外还需要进行变压器零序方向过电流保护动作方向正确性的检查。
The validity check of zero-sequence operating direction for transformer directional over-current protection is also essential.
应检查控制器的测量电流和测量电压的对应关系，测量电流与测量电压应为同相。
Check the corresponding relationship between metering current and metering voltage of controller, the metering current and the metering voltage should be in-phase.
