Answer Posted / anthony
relays are connected to the sec. of a ct . If a large
rating is proposed for the sec. of the ct then it would
mean that the magnetising current (emag. relays) would be
high too, since on the sec. side you have an inductive
relay. This would actually present itself as a load on the
sec.of the ct .

Does the motor power displayed on the Motor name plate is the mechnical power motor delivers or it is consumed power from the system?
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.
