Description
This distance protection relay set up presented in an educational format. For use with Relay Test Set , the relay enables investigations into the protection and monitoring of overhead transmission lines. It consists of
-
- Distance Relay (MICOM P441)
- Test set up
Distance Relay
- The relay module is based on the Micom P441 industrial relay.
- The relay module Can interconnect with test set up the following tests can be performed.
-
-
- Full scheme phase and ground distance protection – up to five zones (ANSI 21G and ANSI 21P)
- Directional/non-directional phase over current (ANSI 50,ANSI 51, ANSI 67)
- Directional/non-directional earth fault (ANSI 50N, ANSI 51N, ANSI 67N)
- Directional/non-directional negative sequence over current (ANSI 46, ANSI 67)
- Thermal overload protection (ANSI 49)
- Broken conductor
- Blocking of any one protection element
- Creating fault and disturbance records
-
- Connection to the experimental circuit is via current transformers with ratio to suit the inputs of the relay. This provides an effective demonstration of the effect of current and voltage transformer ratio, connection and rating on protective relays
RELAY TEST SET UP
