Alstom Relay - Areva Relay - Alstom Relay - Alstom ALSTOM Relay Catalogue - Free Electrical Relays -Alstom Numerical Directional Over ABOUT THE MANUALThis manual is intended to Type CDG 11 Overcurrent and Earthfault Relay Auxiliary Relays for Electrical Substations PRiMA is In an over current relay, there would be essentially a current coil. When normal current flows through this coil, the magnetic effect generated by the coil is not This relay is created by applying intentional time delay after crossing pick up the value of the current. A definite time overcurrent relay can be Definition: The overcurrent relay is defined as the relay, which operates only when the value of the current is greater than the relay setting time. It protects the equipment of the power system from the fault current. Service Manual. Type MCGG. Overcurrent Relays for Phase and Earth Faults.

The fault direction may be forward (between relay and grid), or reverse (between relay and source), the normal power flow being from source to the grid. Overcurrent relaying is the simplest and cheapest type of protection used for protection of lines, transformers, generators and motor. Overcurrent relays Types.
