What is the power factor you maintain at ur organization?
Answer Posted / rajkumar n
power factor is the ratio of true power/apperent power*cos
fay is called power factor.. loads are three types
1.Resistive Load
2.Inductive Load
3.Capacitive Load
Inthis load Resistive load is Unity Powerfactor
Inductive load is Lagging powerfactor
Capacitive Load is Leading Powerfactor
PowerfactorImprovement:
1.Static Capacitor
2.Synchronous condensor
3.Phase Advansor

HELLO EVERYONE, I RECENTLY HAVE FOUND ONE PROBLEM, I WAS TAKING NO LOAD TRIAL OF AN HT MOTOR 920 MOTOR , 1440 RPM , 6.6 KV, WITH AUTO TRANSFORMER. AT 450 V, LOAD WAS 40 AMP AND SPEED WAS 250 RPM. BUT AS WE INCREASE VOLTAGE FROM 450 TO 480V, LOAD BECOME 41 AND SPEED REDUCED TO SOME RPM . SO WHICH PHENOMENON ACTED HERE FOR REDUCING SPEED.?? AND IS IT HAPPENING ALWAYS OR IT IS RARE? I ALSO HAVE FACED SUCH PROBLEM WITH FEW LT MOTOR ALSO.
