PROTECTIVE RELAY TESTING
A comprehensive testing program should simulate fault and normal operating conditions of the relay. Acceptance testing, commissioning, and startup will include control power tests, current transformer

It provides a large set of standardised tests to verify relay performance (operate time, start time, accuracy, security, etc.), but it does not state which is the best relay because this depends on the
Protection Relay Testing and Commissioning
This is a test to check the maximum length of time that the protection relay can withstand an interruption in the auxiliary supply without de-energizing, e.g. switching off, and that when this time is surpassed

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
