Answer Posted / yk
KVA RATING WILL CHANGE PROSNALY WITH FREC IF FREC IS
DECRESED VOLTAGE ON TERMINAL WILL DECREAS AND IF CURRENT
KEPT CONSTANT KVA O/P WILL DECREAS . IF CURRENT IS NOT
CONSTAN THEN FOR SAME KVA CURRENT WILL INCREAS AND
TRANSFORMER WILL BE OVER LOADED .

i am an maintenance engineer. one distribution board have 5 feeder. recently its ELR trips frequently, but it take some times after trip( 10min,20min..)but 3 feeder no load. two feeder only loaded. i checked one feeder IR value all values are above 50Mohm.but B phase to Earth is only 9Mohm.any problem about low value
Thermal withstand capability under full short circuit conditions, in terms of number of times of occurrence of short circuit and corresponding anticipated percentage reduction in transformer life.
As we use capacitor bank in 3ph ckt to improve PF, can we use capacitor in single ph domestric use, in house we have Fan,Mixer,electric cooker,iron,tube choke they also lag the system,because it is inductive load. if it is possible to improve PF of single ph system-- if yes- type of capacitor to be used,connection diagram, working in detail. if no-- list it.
