We Need Your Help with Our Next Protective Relay Online Training Class: Electricity 101!
We’re wrapping up our upcoming protective relay online training class: Understanding and Drawing Phasor Diagrams, and we are ready to get started on the next course about the electrical fundamentals that every relay tester should know. There are a lot of free resources for basic electrical theory out there and we don’t need to re-invent the wheel by describing concepts like “the potential difference between two plates” that create a voltage.
What should a relay tester understand about the electrical system in practical terms?
Here are some of our ideas so far.
Voltage
- Created by the AVR of a generator
- Pressure that drives the current
- Voltages are added up in a series circuit
- Voltages are equal in a parallel circuit
- mv, V, and kV
Current
- Flows through a circuit
- Currents in series are equal
- Currents in parallel add
- mA, A, kA
Resistance
- The load that completes the circuit
- In every part of the electrical system
Ohm’s Law
- Most important formula
- How to re-arrange to calculate V, A, Ohms
Inductive Impedance
- Coil that makes electrical machines work
- Resists changes in current
- Lagging angles
Capacitive Impedance
- Stores energy
- Leading power factor
Watts/VARS/VA and the Power Triangle
Power Factor

Drawing Phasor Diagrams for Relay Testers
Dear Chris ,
I completed both Course 1-1 & 1-2 and ‘m eagerly waiting for the 101 Course :)
Sir it would be so great if you can add a topic on “How to read Electrical Single Line, 3 Line & Schematic Diagrams for swithgears and relays one line diagrams. I have google a lot about this and couldnt find a perfect material to learn this.
And also on how to read Logic Diagrams which consists on the Logic Gates.
Thank you soo much for the courses you have provided and also the manner in which its been taught.
Admire it. :)
Regards
Thanks for the kind words. Reading prints is on our long-term list to do, but not in the 2017 plan this year.
We do cover logic in The Relay Testing Handbook: Principles and Practice which was originally covered in The Relay Testing Handbook #3: Understanding Digital Logic.
Good luck,
