This Application and Testing Electro-Mechanical and Microprocessor Relays Basics (DP 005) course covers the testing of simple overcurrent relays such as time overcurrent, under/overvoltage and over/under frequency electro-mechanical relays.

The course will start with basic level instruction on the construction and principles of electro-mechanical /microprocessor relays, including different components of the relay that need calibration and adjustments as part of testing. It includes 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 junior level technicians who test electro-mechanical/microprocessor relays. It is also valuable to technicians who wish to enhance their knowledge of testing simple relays/elements, as well as those who wish to learn how automated testing is performed to supplement the manual testing that they are practicing presently.
