This Application and Testing Electro-Mechanical and Microprocessor Relays Intermediate (DP 006) course covers the testing of distance, differential, rate of change of frequency, loss of field, reverse power and synchronizing relays.

The course will start with intermediate level instruction on the construction and principles of electromechanical /microprocessor relays, including different components of the relay that need calibration and adjustments as part of testing. It will include a brief description of the relays’ operating principles followed by hands-on testing of the relays using Doble relay test sets.

Using a test plan, manual and automated testing of both microprocessor and electromechanical relays will be a part of the training.


Who Should Attend

This course is ideal for senior and junior level technicians who test electro-mechanical/microprocessor relays. It is also valuable to technicians who wish to learn how automated testing is performed to test moderately complex relays, as well as those who wish to enhance their knowledge of moderately complex relays.
