Finding useful resources for relay testers on the internet is hard.
Valence Electrical Training Services has also created some free content in the following formats:
- A blog about high voltage electrical testing called TechTalk
- A YouTube video series
- Many conference presentations
- Our Ask Chris series where high voltages electrical testers can ask questions, and hopefully get good answers
Hello,
Do you have any videos or training on CT relay connections & polarity ?
The Relay Testing Handbook: Principle and Practice and Electrical Fundamentals for Relay Testing both have the same section on CTs.
This example from a Beckwith manual is also an excellent example of how different CT connections get the same result.
We also talk about CT connections when talking about reviewing drawings and connecting your test-set in our How to Test Protective Relays Online Seminar
Do you have blank test forms available to print? I'm specifically looking for 81 under frequency test forms.
All of our online courses include test sheets. We are currently working on the voltage testing seminar, which will include frequency testing.
