can i connect the two phases of scott connected transformer,if not why?
What are the applications of the electric motors?
at work we have a 3 phase motor but on testing one phase isnt getting a reading. it runs 24 hours a day all week. stops and starts well no noise or heating. the phase isnt down to earth.is it just a bad meter reading or not? phases one and three came up with a resistance reading of 0.4 but phase 2 couldnt get anything shows up as open circuit.
WHY L-G FAULT IS MORE SEVERE IN TERMS OF RRRV?
What is the ratio of true power to apparent power in an ac circuit?
when ac current flows thru d coil of a contactr,it energizes,magnetic field attracts d contact of the coil...nw wont dt ac current in d contct induce current back on to d coil thru mutual inductance leading to high currnt in d coil
