A generating system will have a total capacity of 300 MW. Find the probable forced outage when the capacity is supplied by two 150 MW units. The operating probability of all units is P=0.98 and forced outage probability rate Q =0.02 .
DEAR SIR/MADAM,CLEARLY EXPLAIN ABOUT CRAWLING AND COGGING EFFECTS IN INDUCTION MOTOR.
For a 6.6kV Motor it is recommended to do megger test with 500 V d.c and not more than 5kV d.c but the Hi voltage withstand test should be performed by 12kV AC. Why the dc voltage test should be limited but AC voltage withstand test could be with such a high voltage?
How to decide the size of the capacitor for a single phase induction motor say 2 HP ??
