    (55 customer reviews)

    $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:
    Understanding Phasors and Creating Phasor Drawings

    • What Are Phasors?
    • How to Draw Phasor Diagrams
    • Drawing Phasors with Different Scales

    Create and Understand Phasor Diagrams Used by Different Relay and Test-Set Manufacturers

    • Drawing Phasors with Lagging Angles (Megger and GE SR)
    • Draw Phasors with Positive Angles (Doble and Manta Test Systems)
    • Draw Phasors with Negative Angles (GE UR)
    • Draw Phasors with Positive and Negative Angles (Omicron and SEL)

    Phasor diagrams are your one-stop-shop for understanding an electrical system at a glance. You’d think that all of the relay test-sets, phase-angle meters, and relays would use the same angle systems to communicate this important information to prevent confusion. Unfortunately, you’d be wrong.

    Imagine you’re testing an SEL relay using a Doble test-set and RTS software and you set up a simple three-phase, balanced, metering test (ABC). Each device would display the following angles during a typical meter test:

    1. A-Phase voltage = 0 degrees, B-Phase voltage = 120 degrees, C-Phase voltage = 240 degrees
    2. A-Phase voltage = 0 degrees, B-Phase voltage = -120 degrees, C-Phase voltage = 120 degrees
    3. A-Phase voltage = 0 degrees, B-Phase voltage = 240 degrees, C-Phase voltage = 120 degrees

    [thrive_toggles_group”][thrive_toggles title=”Can you confidently match the angle system to the device? (Write down your answers and click to compare {RTS = ?, SEL = ?, Doble = ?})” no=”1/1″] RTS = 1, SEL = 2, Doble = 3[/thrive_toggles][/thrive_toggles_group]

     

    If you don’t know the difference between devices, you won’t be able to:

    • Perform a meter test properly (more on meter tests in the future)
    • Create effective test-plans
    • Troubleshoot test-plan problems

    Can you believe that there is a fourth angle system out there we haven’t mentioned yet?

    This course will introduce you to phasors and show you how to convert waveform drawings into phasor drawings so that you can understand what phasors are and how they are created.  You will be able to understand what is happening inside your relay and test-set with these topics:

    • What are Phasors?
    • How to Draw Phasor Diagrams
    • Drawing Phasors with Lagging Angles
    • Drawing Phasors with Different Scales

    In a perfect world, these four lessons would be all you needed to become a phasor drawing master. You would be a master at understanding and drawing phasor diagrams in Megger test-sets and GE SR relays but, unfortunately, it seems every manufacturer has a different system for the angles in phasor drawings.  The remaining lessons in this course will help you understand all of the different angle systems used by test-sets from Doble, Omicron, and Manta Test Systems as well as the angle systems used by GE UR and SEL relays:

    • Draw Phasors with Positive Angles
    • Draw Phasors with Negative Angles
    • Draw Phasors with Positive and Negative Angles

    22. A Relay Course Evaluation –

      I’ve done enough coursework in my life in various disciplines and trade crafts to have forgotten some of them. In all of my studies, I have rarely met an instructor who knew their material better, delivered it more clearly and effectively, or who obviously enjoyed teaching their subject more. His class helped me understand relay testing at a level far above what I knew before I took it. It would be difficult to overstate the value of his classes.
