Course 1-1: The Three-Phase Electric Power System (4 NETA CTDs)

Protective relays constantly look at the three-phase electric power system and try to decide whether the system is normal, or under fault conditions. A relay tester who understands the three-phase electrical system can build highly efficient test plans that test the entire relay (not just the individual pieces of it) to make sure it actually operates when it’s supposed to.

In this course, you’ll get an introduction to electrical fundamentals and three-phase electrical power systems, including:

  • How electricity is created
  • How to count cycles and how frequency and cycles are related
  • How to convert from cycles to seconds and back again
  • What three-phase electrical systems are, and how to change from one to another

Course 1-2: Phasor Drawings for Relay Testers (4 NETA CTDs)

Phasor diagrams are used to understand the electrical system at a glance. Unfortunately, your test-set probably has a different phase angle system than your meter or relay, which can make relay testing a nightmare. How are you supposed to translate phase angles between devices that use different references?

​This course introduces you to phasors in 7 detailed video lessons and quizzes, which cover:

  • What phasors are and how to draw them
  • How to convert a waveform drawing into a phasor diagram
  • How to use all of the different angle systems used by both relay and test-set manufacturers, including Megger, Omicron, Manta, GE UR, SEL, and more…

All of our Courses include:

  • High quality presentations with animations describing the theory behind the topic
  • Exercises, quizzes, and real world examples
  • Downloadable content
  • 24/7 unlimited access

The The Three-Phase Power System and Phasor Drawings for Relay Testers online training course are each eligible for 4 NETA Continuing Technical Development Credits (CTDs). NETA Certified Technicians (Level III and Level IV) are required to earn a minimum of 48 CTDs every three years to maintain their certification. For more information about the CTD program and requirements, please contact the NETA office at [email protected] or 888-300-6382.
