2nd, Examine if capacitive latest of cable is a lot less than your setting. 2A would seem is lower setting, for cable sizing, from 120mm^2 is below 1km lenght.
Relay defense coordination: HY-ZCT performs a vital purpose in relay protection coordination. By correctly measuring the residual current beneath fault situations, they offer input to protective relays to initiate correct protective action.
T相には地絡点から対地静電容量を通って地絡電流は流れないのでしょうか。

Zero sequence current transformers are flexible within their application. They can be installed on person phases of three-phase lines, handed by means of all three-stage conductors collectively, or placed on the neutral line. This flexibility allows them to successfully check the vector sum of 3-stage currents:
These zero-stage molded present transformers shield the power method versus leakage and earth faults. Just about every of such latest transformers has an insulation amount of 0.72 kV and requires a suitably insulated Main conductor.
Do not have use of the guide now but I am relatively confident the 750 also internally calculates the residual (imbalance) on the period currents(most microprocessor relays do this). I feel the handbook will connect with the calculated residual fifty/51N as opposed to fifty/51G. Or a thing like that. Alan

Ground Fault Detection: On the list of most important applications with the HY-ZCT is ground fault detection. By measuring zero sequence current, these transformers can detect the presence of floor faults, which manifest when recent flows from a section conductor to ground.

Due to the fact we are coping with The site present transformer, We are going to attempt to apply Kirchhoff’s Current Legislation listed here. Considering the fact that a three stage procedure is A 3 AC existing with shifted period. From the KCL, we realize that:
