why DC source is used to idetify the polarity of CT/PT?
Why current flows in nutral? As per theory there should be no current in 3 ph explain.
to operate air conditioner of 1.5ton what power of generator is required
In Delta connected capcitor bank, One bank failed due to some problem. Can we connect Open delta capacitor bank to 3 phase motor. The motor voltage rating is 6.6KV. IF yes what changes will happen?
why Copper loss is represented as I square R ?
Define settling time.
What are the types of power in electrical power?
how many types are their in switchyard or substation(like D,I TYPE), what is differant between them
what happens when power factor leads or lags to electical or home appliances
Define phase lag and phase lead?
When measuring the Insulation resistance of a motor winding (winding to earth) using a megger meter, Applied voltage(1000V) was automatically reduced to 500V. and the measured insulation resistance values are also very low (in Kohm range) Can anyone give me a reason???
Which addressing mode contains the address for data as a part of the instruction in 8085.
I have a drawing of a wound rotor induction motor for a crane. This crane motor has 5 forward speeds & 5 reverse speed implemented of course with different amount of resistance for each speed setting selected. What has got me scratching around is the fact that 8 of the 10 speed selections switch in uneven (unbalanced) amounts of resistances on each of the 3 connections to the motor's rotor.Can this be possible? I would have assumed this would produce unbalanced rotor currents and therefore vibration in the motor. I would greatly appreciate anyone's comments on this. Many thanks, Confused.
