what is the difference between isolator and circuit breaker
Answer Posted / snowwhite10
isolator is a knife switch and it is used to open a circuit
under no load.such switches are used in the both sides of
the circuit breakers so that repair and replacement of the
circuit breakers could be done.they are never opened when
current is flowing in the line.....
circuit breaker is an equipmnet which can make or break
contacts under load ,no load or fault conditionsrelay is
always used with circuit breaker ..relay detects the fault
and circuit breakers does the function of current interruption..

A 400 V, 50 Hz, Δ connected synchronous generator has a field reactance of 0.1 Ω and armature resistance of 0.015 Ω. At full load, the machine supplies 1200 A at 0.8 pf lagging. Under full-load conditions, the friction and windage losses are 40 KW and the core losses are 30 KW. What is the machine’s overall efficiency? Ignore any field circuit losses.

In Power Line Communication (PLC) the wave trap is used to block communication signals from entering neighboring lines. My question is this: Why do they allow for different filtering arrangements on these wave traps? Isn't it always going to be a low pass filter since we want the power frequency to go through, and the comm signal blocked?
