Applications of relays are found everywhere; in switchgear industry, relays are used in all types of switchboards. The concept of employing numerical relays for substation and switchgear protection has existed for three decades. This has now matured into a stable alternative to conventional electromechanical & electromagnetic Relays.

Here’s what makes numerical relays a better choice over everything else:

  • More accurate
  • Microprocessor based multi-stage protection
  • Multiple combinations of interlocking
  • Complex scheme logics with no need of intensive wiring.

With more than half a century of experience, E&A has developed capabilities for in house production of relays – the COMP series. These relays for motors, feeders, transformers, and the arc flash relays add intelligence to your switchboards.
