racobb (Electrical) 11 Nov 09 21:12 I think your knowing is wrong. A CT just measures present and it truly is your decision to find out just what the CT is measuring and type of relay you connect it to And the way you established the relay. Course is a selected kind of relay, not a CT function or CT structure/link.
対地静電容量を通じて流れた電流は受電設備の変圧器巻線を通って地絡した相に向かって流入し、地絡点に向かって流れます。地絡電流はこうして流れ続けます。
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 transformer HY-ZCT is often a recent transformer specially utilized to evaluate or detect the zero sequence component of present-day in a few phase electricity process.
Zero sequence present transformers are adaptable within their application. They are often set up on specific phases of 3-period traces, passed by means of all 3-stage conductors collectively, or placed on the neutral line. This versatility enables them to successfully watch the vector sum of 3-stage currents:
Created to secure the ability system in opposition to leakage and earth faults, these zero-section existing transformers (ZCT) are available numerous window diameters. Epoxy-Solid coil. CIC is website an industrial quality current transformers, voltage transformers, distribution transformers, epoxy insulators and electric power capacitors manufacturer from Taiwan. With in excess of forty five decades of expertise and know-how collaboration with Germany's MWB, CIC is ISO Qualified and gives solutions regarded for dependability in several industrial purposes.
The resultant flux is zero (Φr = 0). This suggests there isn't any existing flowing throughout the secondary circuit of our CBCT. Its earth fault relay gained’t get operated considering the fact that this is the standard Procedure.

This triggers a trip mechanism, correctly isolating the faulted part to stop destruction and make certain safety.
三相交流電源では、それぞれに流れる電流が等しく対称である場合、そのベクトルの和はゼロです。
The 750 also enables you to setups fifty/51N things employing a derived value in the three period inputs. These are typically build as "Neutral Recent" from the setpoints.
