Protection Coordination Study (ETAP)

Home / Services / Protection Coordination Study (ETAP)

service overview

ETAP-based protection coordination studies and relay settings so that faults are cleared quickly and safely.

Proper coordination means only the faulty section trips while the rest of your plant keeps running.

Protection Coordination Study (ETAP)

When a fault occurs in your electrical system, the nearest breaker should trip first and the rest of the plant should keep running. If your relays are not properly coordinated, a small fault in one section can shut down the whole facility. This is where a protection coordination study becomes essential.

B.E.S.T performs protection coordination studies on ETAP, the industry standard software, backed by practical relay testing experience on real sites. We calculate fault levels, prepare relay settings, and verify them with primary and secondary injection testing, so your protection scheme works exactly as designed.

Key Tasks & Activities:

Our study covers:

  • Data collection from your single line diagram
  • Fault level calculations
  • Relay coordination on ETAP
  • Relay settings and grading
  • Primary and secondary injection testing
  • Verification of CT/PT ratios
  • Final report with recommendations

Benefits:

A proper coordination study gives you:

  • Only the faulty section trips, not the whole plant.
  • Protection of costly equipment during faults.
  • Compliance with utility and insurance requirements.
  • Confidence that relay settings are correct and tested.
  • A clear report you can use for future expansions.

We performed coordination studies for the Pakistan Deep Water Container Port project, and we can do the same for your facility. Get in touch for a study proposal.
