Abstract :
Test switches used in protective relay schemes are selected based on quality, price and convenience features. The criteria selection assumes all the switches perform the basic functions they are intended to perform. This paper questions that basic assumption and performs an evaluation of existing offerings, and analyzes the impact of their performance in the power system.
