In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected. ... The theory and application of these protective devices is an important part of the education of a power engineer who specializes in power system protection.

2. About Us
We entered the market in 2002 in the Electric Testing & Maintenance – a field that is
entirely uninteresting to the casual market observer! The players in this market
were reactionary and engaged only when called upon in crisis. System Protection
created value with the first-ever Managed Services offering in the Electric Relaying
& Protection Engineering domain. System Protection started expanding the
boundaries and changing the game by employing only selected first class Engineers
as against a bunch of Diploma holder footmen. By introducing tactical innovations
like: Health checkup and predictive system failure reports, System Protection
engineers were now creating new value and system level insights for over 40% of the
industrial clients in Gujarat alone.

• The prompt removal
of the component which is
behaving abnormally by
closing the trip circuit of the
circuit breaker or to sound
an alarm.

6. • Disconnect the abnormally
operating part so as to avoid the
damage or interference within the
effective operation of the rest of the
system.

7. • Prevent the subsequent faults
by disconnecting the abnormally
operating part.

8. Disconnect the faulty part as
quickly as possible so as to
minimize the damage to the
faulty part itself. For example, if
there is a winding fault in a
machine and if it persists for a
long time then there is a
possibility of the damage of the
entire winding.
As against this, if it is
disconnected quickly then
only a few coils may get
damaged instead of the entire
winding.

9. • Restrict the spreading of
the effect of the fault causing the
least interference to the rest of
the healthy system. Thus by
disconnecting the faulty part, the
fault effects get localized.
