how to control the speed to switched reluctance motor
ACCORDING TO IEC WHAT SHOULD BE THE MINIMUM HEIGHT OF G.I. STRUCTURE OF CT, PT, ISOLATOR, LA?
At the starting of dc motor and syn.motor and induction motor high current flowing through the winding. Due to this the windings burnt out. To avoid this different types of starters are used. But incase of transformer what Will be used (At starting no emf is induced in the primary winding)?
Tell me the reason of connecting domestic t/f primary in star or delta,and also secondary side.
-What should be minimum value of insulation resistance and maximum value of earth resistance at any electrical instillation and what is method of testing the same.
What are test values for an 63 KVA and 100 Kva Distribution Transformers for the following typical tests 1)Magnetic balance 2)Short circuit test 3)Open Circuit test 4)Vector group confirmation test .please give me the standard values for all the above tests.
If we connect a motor and generator together (I mean that the generator gives the motor electricity and the motor gives the generator movement) regardless the losses. Will the generator still generate and the motor still move?
why does the magnetic balance tests at transformer?
