Protection Relay Test Set
Model Number: PSL50
For comprehensive investigations into the theory and practice of electrical power system protection.
Overview
A test set that gives students theoretical and practical experience with a variety of industrial relays. The equipment uses industrial protection equipment and techniques, and a range of industrial relays, adapted for educational use. The test set allows students to compare individual relay characteristics. It also allows connection of two relays for experiments such as relay discrimination. The test set includes meters, current and voltage transformers (CTs and VTs), power supplies, a configurable transformer and load resistors. Controls on the lower panel of the test set allow the user to adjust the test voltage supply, current and load resistances. A transmission line on the upper panel of the test set allows students to set up distance protection and parallel feeder tests.
