Is there any reason that a vertical motor can not be mounted horizontally ? I happen to have one and would like to use it horizontally to save money by not buying a new horizontal motor.
1 3508is there any chance to get shock from the transformer oil at the time of maintenance due to its dielectric property. . ?
Bhel,
6 8708in underground cables, we have a grading method called 'capacitance grading' why is it called 'capacotance grading' although we do not use any capacitor in it?
1 5405what 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 7816I 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?
