A tool for calculation of relay settings for power transmission and sub-transmission substations.

This tool covers all the relays of the substations beginning with outgoing medium voltage feeders of sub-transmission substations to all the relays of transmission substations and power plant substations, including the relay types:

Line feeders protection

  • Distance protection
  • Over-current protection
  • Line Differential protection
  • Voltage and frequency protection
  • Reclosers
  • Breaker protection
  • Teleprotection


Transformer feeders protection

  • Over-current protection
  • Transformer Differential protection
  • Restricted earth fault protection (REF)
  • Voltage and frequency protection
  • Over-flux protection

Busbar protection

Reactor protection

Capacitor bank protection
