Faults that can occur in 3 phase induction motors and associated protections are discussed below: Stator faults: These faults include…
During normal operation of the Synchronous Generator or Alternator excitation to the rotor is provided by the small DC generator…
Normally the rating of synchronous generators or alternators will be in KVA or MVA instead of kW rating. Electrical apparatus…
HV 6.6kV Induction motor Protection For HV motors rated 6.6kV and above motor over current, stalled rotor, and short circuit…
Synchronous motors are not self starting machines. These machines are made self starting by providing a special winding in the…
For industrial squirrel cage induction motors are used mostly for the motor and drive systems applications. Synchronous motors are very…
Cooling system should be provided in the generator or alternator to remove the heat generated in the windings (I2R loss)…
Variable Speed Drives (VSDs) are employed in the industrial applications where different speeds are require to operate certain process systems.…
In industries induction motors are employed mostly because of less cost, rugged construction, good starting torques and very less maintenance.…
