About This Product
The lecturer or student builds fault circuits on the test set, connects the relay and programs the settings needed for each test. Most tests use a single relay, although the test set has enough connections for two relay modules to be tested at the same time. Schools, colleges and institutes in Armenia, Tajikistan, Moldova, Niger, Ecuador and Turkey can order the Earth Fault Overcurrent Relay from Educational Instrument.
