Overcurrent & Earth Fault Relay 51P/51N Protection Switchgear Block
Developed by Rodney Tan (PhD)
Version 1.0 (Jun 2023)
This block combine Overcurrent & Earth Fault Relay (ANSI/IEEE C37.2 device number 51P/51N) that operates when the current exceeds a predetermined value.
Relay operates based on IEC 60255 Standard Normal Inverse IDMT (Inverse Definite Minimum Time) trip characteristic.
User is allow to set the both relays Plug Setting (PS) in percentage and Time Mulitplier Setting (TMS) for distribution line protection.
User can also choose to Enable or Disable relay for protection coordination study.
