Relay coordination Studies  Want us to call you

Objective of Relay Coordination:

A coordination study consists of the selection or setting of all series protective devices from the load upstream to the power supply. In selecting or setting these protective devices, a comparison is made of the operating times of all the devices in response to various levels of overcurrent. The objective is to design a selectively coordinated electrical power system.

Proper application and coordination of over-current relays and other protective devices is vital in a system requiring reliable electrical service. expert engineers bring the critical experience needed for the proper application of ANSI and NEC requirements to equipment protection.

In addition to relays that respond to short circuits, low-voltage breakers, differential, directional, power, under-voltage, out-of-step, and other special protective relays often need to be set.

Scope of Study

  • Time overcurrent setting (phase)
  • Time overcurrent setting (earth)
  • Instantaneous overcurrent setting (Phase)
  • Instantaneous overcurrent setting (earth)

Standard & Regulations

To the extent possible the audit will follow all applicable standards (international)
