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!
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:
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:
You can watch a 10-minute video below that will give you an introduction to the topics covered in this course.
