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

    $49.95 USD

    Waveform diagrams contain every detail of an electrical system, but that information can be difficult to understand without a lot of effort. Phasor drawings take the complex information embedded in waveform drawings and convert it into phasor diagrams so that you can see the most important information about an electrical system at a glance. Understanding phasor drawings is probably one of the most important skills that a relay tester must have to be successful!

    Take this course to learn these topics:
