Good information. Thats why i asked! thanks.Obviously class 0 gloves for shock protection, maybe class 2 gloves if you are reaching within the RAB of the 12.47kV. But that is the least of your concerns, you are going to have a serious are flash hazard there since there is no OCPD that will clear an arcing fault on the secondary within a reasonable time, you would default to 2 seconds, and your fault current will be based off the transformer kVA, so to know for sure you need to do an arc flash analysis but I will save you time, expect it to be >40 cal/cm2 (Pretty sure it would be if you did the study) so really no PPE will provide protection from an arc flash.
I don't see how you can justify doing that energized
Just my two cents worth...Good information. Thats why i asked! thanks.
Do you have anything to add?
Something else after reading your profile...Does anyone know the proper PPE category for the following:
Opening the hinge on the utility pad mount XFMR to place the split core CT's around the wiring (insulated wiring).
Shut the lid.
i'm looking at the picture, and 12kv is 2'0" closest point of approach... so
That water cooler in the lunch room is important. you may be able to pull a hot work permit for that.The primary side shouldn't be an issue, because it shouldn't be open while you are installing the ct's, it would be a whole lot easier and safer to go ahead and just shut the transformer down, and install them on the buss bar. What is this running that is so important that it can't be shut down?
