I discovered Within this post that a metering course cannot be made use of for defense. What difficulties could probably In any case In case the CT's are replaced in purposes.

Do not have usage of the guide now but I am fairly sure the 750 also internally calculates the residual (imbalance) with the section currents(most microprocessor relays try this). I think the guide will connect with the calculated residual 50/51N versus fifty/51G. Or something like more info that. Alan
三相のいずれかに地絡電流が流れると、三相のバランスが崩れて零相電流はゼロとなりません。これにより地絡事故をただちに発見することができます。

Due to this fact, the CBCT’s secondary-connected earth fault relay will become activated, isolating the wellbeing system by using a circuit breaker.
継電器（リレー）や遮断器とともに漏電遮断器に内蔵されることが多く、事故や火災などの災害につながる漏電を防ぐ上で重要な役割を担っています。 参考文献

地絡時には零相変流器が作動することにより、故障個所を周囲の電気回路からただちに切り離されます。
Zero sequence current transformers are multipurpose within their application. They may be set up on person phases of a few-stage traces, passed via all a few-stage conductors collectively, or put on the neutral line. This adaptability lets them to properly keep track of the vector sum of three-section currents:
The Main balance present transformer (CBCT) is especially utilized for earth fault defense of electrical machines. One among its important programs is earth fault security of induction motors, that's discussed under in detail.
The installation of the proper form of CT determined by the particular defense requires plus the procedure’s operational characteristics can noticeably greatly enhance technique dependability and security.
