1) Who exactly text absence of high voltage potential at field or equipment before work is done after breaker is racked out through loto process? Like you explained there could be mistake in racking out right breaker? 2) What is the name of test tool the test High voltage presence or other best way to test ?
The person doing the work will verify by procedure that clearances are in place as well as physically confirm (by measurement) that clearances have been established. For HV, primary voltages may not be easily accessible, so secondary voltages can be used to confirm proper clearances are in place. For HV, it is often easy to see that areas are isolated by viewing MODs or large air insulated disconnects, and that ground chains are in place before starting the work. Keep in mind that if someone is not certified for HV work, then they won’t be accessing HV systems. The HV team will have the hot sticks and measurement equipment to access HV systems.
Nice video. Keep sharing the Information.
Very good training video, congratulations. Keep it up
Great training presentation by Paul Turner on Safety during commissioning, appreciate 👍
Thanks for the feedback. If you have a suggestion for topics to cover in future videos, please let me know.
THANK YOU so much so
Thanks much Mr. Paul Turner your great inputs on this critical topic. I am not able to use the link to download my certificate of participation.
Hi, this was an old webinar, so the certificate is not available anymore.
Nice short training module 👍
Hi Prianto, thank you for your feedback. We are glad you enjoyed it.
