Answer Posted / thabani chinhara
In power systems an isolator is a switch which is used to
completely open a circuit which has been rendered dead by
means of opening a circuit breaker for maintenance of
equipment. It can be visually seen that an isolator is open
and hence service men are assured that it is safe to work
on the isolated equipment. The equipment to be worked on is
further earthed mostly on either side so that electrical
energy that could be in the equipment is completely
discharged to earth further enhancing safety of the service
men. An isolator is also used for sectionalising power
lines during fault location. An isolator, unlike an auto
disconnector is not used to break load or close a loaded
circuit. An auto disconnector opens and closes a circuit
with limited load. Isolators are used at homes to isolalate
appliances with circuit breakers that are out of sight of
the service men in charge of repairing the appliances.
These isolators are therefore installed near the
appliances such as air conditioners.
