Product Description

Description:

A test set that gives students theoretical and practical experiencewith a variety of industrial relays. The equipment uses industrial protectionequipment and techniques, and a range of industrial relays, adapted foreducational use. The test set allows students to compare individual relaycharacteristics. It also allows connection of two relays for experiments suchas relay discrimination. The test set includes meters, current and voltagetransformers power supplies, a configurable transformer and load resistors. Italso has a useful desk space for students to work on. The configurabletransformer has a star connected primary, but the secondary has multipletappings. So, the user may connect it as delta or star with different voltageratios. Controls on the lower panel of the test set allow the user to adjustthe test voltage supply, current and load resistances. A transmission line onthe upper panel of the test set allows students to set up distance protectionand parallel feeder tests.
