From, which load current range ( upper - lower limit current)can Air circuit breaker used for in electrical circuit.
why ct's&pt'S out put called as burden,why compelsary short ckt the secondary of ct's while removing the burden?
Safety of on line ups
The loads are connected with phase and ground then why current flow as the loads ?
Dear all, I want to use Induction motor to open and close a 1 ton door. How much power do I need. Thanks
The transmission does not have options: a)Partition noise b) Flicker noise c) resistance d) Short noise and reason
how we calculate torque ? how we improve it ?where torque will either motor or generator ?
