How not to overspecify high voltage CTs and VTs | EEP· Measure #9 – For class PS CTs, the value of the knee point voltage V K is specified as:. V K ≥ K × I × (R CT + 2R L) × V. where: K = constant governed by system parameters and relay characteristics (a typical value being 40),; I = rated relay current (1 or 5 A), (for delta connected CTs, this value is obtained by multiplying 13 to CT secondary current),; R CT = ac resistance of ...

Switchgear Testing Solutions - SMC breakers and switchgears need routine maintenance and testing to be sure that they will function reliably. Switchgear must interrupt fault currents several times the rated current, so that simulation of the fault conditions through primary injection is required in switchgear testing for both the breaker and the whole assembly performance.

Thermal decomposition characteristics and kinetic analysis ...· In recent years, the C 4 F 7 N/CO 2 gas mixture has been considered one of the most promising candidates to replace the strong greenhouse gas SF 6 in high-voltage power equipment. However, there are few studies on the thermal stability of the C 4 F 7 N/CO 2 gas mixture. In this paper, the characteristics and mechanism of the thermal decomposition of C 4 F 7 N/CO 2 gas mixture are …
