About This Product
The test set gives students theory and hands-on practice with real protection relays. They set up faults, vary the test voltage, current and load, and record how each relay responds, then pair two relays to see how discrimination isolates only the faulted section. Schools, colleges and institutes in Georgia, Samoa, Paraguay, Bahamas, United Kingdom and Djibouti can order the Protection Relay Test Set from Educational Instrument.
Frequently Asked Questions
Can two relays be tested together on the Protection Relay Test Set?
Yes. The test set allows two relays to be connected for experiments such as relay discrimination.
How can the configurable transformer be connected?
It has a star-connected primary and a secondary with multiple tappings, so it can be connected as delta or star with different voltage ratios.
