|How can make a star delta with Rstar delta feeder
( ( 4contactor & one timer ) pls answer with digram (power &control
|Why is it that bus reactors are not accompanied by a neutral
grounding reactor whereas a line shunt reactor is? PGCIL
|What is Star Delta Connection, where it is applied & what
for it is used
|IN 3 phase induction motor where we give i/p supply & how
its working ?
|What are the role of each components in PID COntroller
|We have 2 Nos. Transformer with the capacity of 2000KVA and
1250 KVA and currently using only one 2000KVA T/R during
operational hours while non- operational hous 1250 KVA T/R
also used to reduce T & D losses. Similarly, 2 capacitor
bank of 500KVAR and 300 KVAR also installed to balance
reactive power. Now problem is around 1000 KW load PF is
not maintaning 0.99 as 350 KVAR capacitor is in healty
condtion. Now the PF is maintain 0.95 to 0.96.
|1.What is the difference between isolators and
2.What is bus-bar?
|What is the difference between a Distribution Transformer
and a Power Transformer.
|why ohmas low not sutable to transformer.
|If a motor of 8.5 KW with same load and using in both Star
& Delta one by one,then which will take more current in
star connected or in delta connected
|From the point of view of accuracy in the Measurement of
Electrical energy should we select a potential transformer
or a capacitor voltage transformers?.Kindly support your
reply with reason and justification.
|In our homes we place the 5Amps fuse...now in our house only
takes 5Amps for all normal conditions ha???
