Overload relay – Principle of operation, types, connection

Every motor must be protected from all possible faults to ensure prolonged and safe operation as well as time loss caused due to breakdown. Almost all industries rely on the electric motor to control their processes and production. Hence it is necessary to make the motor fail-safe. The most vulnerable part of a motor is … Read more

Difference between Short circuit and overload

Short Circuit A short circuit occurs when two or more current-carrying conductors of different phases or different voltage levels or different terminal (in DC circuits) come in contact with each other or with the ground. It is an abnormal condition during which current shoots up several times the permissible limits. Read about short circuits in … Read more
