how to compare with Relay settings for HT< panels, RMU panel, and PSS CSS transformer?? 1) Load amps, 2)Tripping time, 3) CT ratio, 4)Cable size 5) Transformer KVA rating 6) transformer full load amps
686how to setting Load amps tripping time and extra settings for load Transformer protection relay with RMU panel using C&S model relay..?
558In Air circuit breaker LSIG protection unit is used. Without fault in cables (2 runs 3Cx150Sq.mm Copper, 1Kv grade, XPLE armored cable IR value is more than 550Mohm @ 500V Megger) and load section Long time Overcurrent protection is triggers and trips the unit. We changed LSIG protection with new factory tested unit. Even then fault is persisting. Please suggest the possible causes
325An impedance of 100 ohms resistance and an unknown inductance is connected across the capacitor. The resulting impedance is a pure resistance of 500 ohms ifω = 10^5 rad/sec. calculate the values of inductor and capacitor.
