Protection Relay Test Systemk

Protection relays play a critical role in the safety and reliability of today electric transmission and distribution systems. MELSS has worked with several major protection relay manufacturers and has designed systems to test different kinds of:

  • Numerical relays
  • Electro-mechanical relays
  • Remote terminal units

Three major functions in the test systems of protection relays are:

  • Main protection tests & ancillary protection
  • Data logging & communication
  • Dielectric safety tests

The number of variants in Relays varies depending upon the Protection application and the power rating of the line.  MELSS has built testers for various rating of power.

  • Power sources
  • Programmable AC source – 3 phase
  • Configurable current source – calibration
  • Programmable DC source

Measurement Instruments:

  • Digital power meter/power analyser
  • Digital oscilloscope
  • Industrial computer/PXI system
  • High power switch matrix
  • Touch screen monitor/keyboard/mouse
