in my industry we are using 3 step up transformers for induction heaters..i.e 415/580v and other are 11/440v.in power consumption does a step trnsformer makes any difference compared to step up?? plz explain
1431Is there any decided or standard frequency to check the meager testing of transformer, DG set, LT Panel in the industries in a year. I means how many times we should be check the same.
2 3667Difference between induction motor and synchronous motor? i Think Synchronous motors operate at synchronous speed (RPM=120f/p) while induction motors operate at less than synchronous speed (RPM=120f/p – slip). Slip is nearly zero at zero load torque and increases as load torque increases am a right pls guide & send Other Comments
