Instantaneous OC Relay Setting - Biggest Mistake Engineers Make

When setting an instantaneous overcurrent relay, should you consider peak current, symmetrical current, or asymmetrical current?

In this short video, understand:
- Why instantaneous settings are based on asymmetrical through fault current
- Why peak current is NOT used for relay coordination
- Difference between symmetrical, asymmetrical, and peak fault current
- Why peak current matters mainly for circuit breaker selection and electrodynamic stress checks

A must-know concept for protection engineers and power system professionals.
