FIST 3-8-March18-2010

When functional testing relays, the requirements or mandated activities referenced in this FIST apply to relay settings that could lead to a trip or alarm. Relay elements that are disabled do not need to be

Basic protection relay knowledge

Definite time delay means that the protection operate time dose not change or depend on the fault type or the fault current magnitude. Inverse time delay, on the other hand, depends on the current

Protective Relay Basics

Relay curves show only the time for the relay itself to operate and do not include additional time required to trip and clear the fault. The relay curve is shown as the dark blue line.

Distribution Automation Handbook

The operating time of definite time relays does not depend on the magnitude of the fault cur-rent, while the operating time of inverse time relays is shorter the higher the fault current magnitude is. The time
