Explain Creepage Distance of Insulator
The gauge indicates the number of amps, but what about voltage? How voltage rating (for wire or fuse) determined?
Can anybody just suggest about the scope of Electrical design with ETAP software?Just guide me?
Why a Permanent Magnet Generator has higher frequency as compared to frequency of main alternator?
What effect does a very low impedance have on the Voltage regulation? On the short-circuit current?
what is the use of commutator in dc motor if we supply ac ? commutator is used to convert ac to dc.and it is used to arrange the flux in unidirectional in case of dc supply. if we give ac as supply to dc motor what is the use of commutator?
For electrical designers what are the standard should know? i want learn about this standards. how to get information/reference. anybody help in this regards please.
What is a DC series motor?
Is electro plating what type of load whether resistive, inductive or capacitive loads
how to know the diffrential relay setting of 06mva step- down (delta-star)transformer?
Main advantage of auto transformer over two windings transformer is that A it needs no cooling B it uses only one winding C core losses are reduced D it has simple construction
What is dc current source?
1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2. Similarly for AC generator and AC motor 3. similarly if using DC batteries instead of DC generator, What happens?
What should be the voltage between Neutral and Ground in secondary side of the step down transformer (230 V to 110 V) with no load condition?
what is the method of earthing of a transformer using electrodes?
