Online Relay Testing Training

We just released our latest online training course about phasor diagrams for relay testers and this video summarizes the topics in that course:

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!

You can 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 high voltage equipment 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)
