摘要(Abstract):
发电机出口的大电流互感器受安装位置和一次通过电流较大的限制,现场进行误差试验较为困难。研究采用等安匝法和负荷误差外推法相结合的方案,解决了发电机出口电流互感器现场误差试验的难题。
On-site error verification is difficult since the high current transformer of generator outlet is constrained by the installation position and high primary current.This paper solves the problem of on-site error verification for the current transformer of generator outlet by adopting a scheme which combines equal ampere-turns and load error extrapolation methods.
