What is power factof?..

Answer / prasad

POWER FACTOR IS COSINE OF ANGLE BETWEEN VOLTAGE & CURRENT
IN AC CKT. HOWEVER IN SIMPLE TERMS IT CAN BE DESCRIBED AS
EFFICIENCY FACTOR OF LOAD IN p.u. IT SIGNIFIES WHAT AMOUNT
OF ELECTRICAL ENERGY IS REQD BY LOAD WITH A GIVEN P.F.
THUS IF TWO MOTORS OF SAY 80 KW WITH ONE HAVING P.F. 0.8
& OTHER HAVING PF 0.85, THEN FOR RATED LOAD FIRST MOTOR
WILL REQUIRE 100KVA WHILE OTHER MOTOR WILL REQUIRE 94.1KVA
OF ENERGY
