Circuit Breaker is a device which can
Make or break circuit under normal conditions either manually or through remote control.
Break circuit automatically under faulty conditions.
Make or break circuit under faulty conditions either manually or through remote control.
Some types of circuit breakers are Air blast circuit breakers,Vaccum Circuit Breakers ,SF6 Circuit Breakers,etc.You can notice the circuit breakers near to the transformers.Next time when you see a transformer search for the circuit breaker.Mostly it will be SF6 Circuit Breakers.
Isolator or Isolating Switch is a device which is used to disconnect a part of the system for maintanance purpose and repairs.Isolator can open a circuit under no load condition only.If two isolators are connected on either sides of circuit breaker,then the circuit breaker must be opened before opening the isolators.
After perfoming maitanancee work on the circuit breaker,isolators must be closed first and then the circuit breaker must be closed to bring the system into operation.

A 15 kw squirrel cage motor having a maximum efficiency of 90% on a continuous full load has temperature rise of 42 degrees celcius after 30 min and 52 degrees celcius after 1 hr under the above operation conditions. a) calculate its final steady state temperature rise on continuous load and the heating time constatnt. b) if the motor is operated on a short load for 9 min estimate its temperature rise. c) calculate the maximum overload that can be applied on a short, 9 min rating so that the temperature rise is the same as the final steady state temperature rise on continuous load.
