Engineering AllOther (1379) what do you mean by PF correction. A motor is rated at 15 kw,415 volts, 0.7 pf and eff of 0.92. The powerfactor is improved to 0.98 by adding capacitors at the bus. calculate the current drawn by motor under full load condition before and after pf correction
5 7508I have 90KW Motor 60 Hz,380V Pf 0,88. after testing the Motor without Load is the no load Current 36 A,but wenn i put load after 2 hours the current increase more than 156 A. Can anybode tell me waht is the Problem?
