The blanket is the space between the oil and the top of the XFMR and varies per size(depth of head) and manufacturer. Could be 10" or 3", nevertheless, most gasses are lighter and will rise to the top in oil and this would be the compartment that accumulates the 'air' and technically exhaust it...
If the Total Combustible Gasses (TCG)% is higher than the Safe Handling Limit (SHL)% that unit should be taken offline, deenergized, and purged with nitrogen. Make sure you are not using anything that creates an arc; vehicle, pump, lighter and so forth. If so installed on the XFMR, the...
The possibility is that the CT's are disconnected in the tank. It is the last step I wanted to take, but really it is the next one. I appreciate your insight, take care, HornTootinEE
HornTootinEE,
Thank you for the reply. I have covered most of the issues you mentioned: AutoINhibit is asserted when no current is sensed, IL, current is measured at zero, resulting in the NO torque region. And we captured the metering of each unit and sure enough, we are unable to get the units...
I am looking for info on Schweitzer 2431 controllers, specifically for a Siemens JFR voltage regulator. I have three units on a three phase distribution system, being feed from reverse(source side voltage is supplied onto the L bushing, load voltage on the S bushing)with the controller mode set...
Thanks Marmite-I have some PCB data sheets from over the years that list manufactures use in their products, but it is little to go on with the regulations that are in effect. Appreciate your help.
Hey, I am trying to find a database of transformers (manufacturer, serial number)that references when their products might of been filled with PCB's and when they discontinued using them. I appreciate the help.
Can anyone suggest a high amperage(2000 amps max)tester? Used primarily for single phase reclosers, three phase reclosers and sectionalizers? Appreciate your time
I was wondering about a 10000 KVA transformer used for commercial/residential distribution and the operation of the parallel/independent switch mounted in the LTC cabinet. We have one in our system that is a lone model and the selector switch is selected in the 'Parallel' mode. I think it got...
