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.
A transmission line on the upper panel of the test set allows students to set up distance protection and parallel feeder tests.
The configurable transformer has a star connected primary, but the secondary has multiple tappings. So, the user may connect it as delta or star with different voltage ratios.
Controls on the lower panel of the test set allow the user to adjust the test voltage supply, current and load resistances.
The test set includes meters, current and voltage transformers, power supplies, a configurable transformer and load resistors. It also has a useful desk space for students to work on.
