Can you calculate symmetrical components from the given three-phase voltage (or current) quantities?

Have you ever wondered how to convert primary impedance values to secondary values for relay testing purposes?

Do you know how to calculate the phase-to-phase voltage from any two phase-to-neutral voltages?

Even fault values?

Can you find the apparent fault (or load) impedance from a given set of phase values?

Can you convert polar coordinate values to their rectangular coordinate equivalent ? And back again ?

Do you know how (and why) to force neutral current through your protective relay systems?

Can you predict the amount of neutral current flowing?

All of the answers, and more, are available from this site. The software and training that we offer can help you become a better Power Systems Protective Relay Technician.

This site will introduce you to some software tools that should be a part of your protective relay maintenance tool kit. If you have a laptop PC running Windows(TM) then these programs will help you in the field or in your training sessions. Imagine, finally being able to calculate the many needed values that you encounter when testing complex protective relays.

The calculations that you will learn can be applied to generation (symmetrical components) and transmission protective relays (apparent impedance). The confidence that you gain as a result is immeasurable!

In addition to offering software for sale we can provide instruction at your site. We will present lectures, give tests and load and demonstrate our software in your PC's. We attempt to take the mystery out of relay testing. If you have basic trigonometry, an intro to power system protective relays and a desire to understand more about what you are testing then we can help.
