I don't know that lightning plays a big part, but it's possible. From my perspective it seems like when you have a single bus configuration, it's not unreasonable to want to restore it for a fault that could likely be temporary. Unlike ringbus, or breaker and half schemes, every line would be...
I'm hoping someone here is familiar with this approach. The utility I came from before relocating to Georgia never used such a practice. The basic issue is this: Say you have a transmission substation (100kV and above) that is constructed in the single bus configuration (i'm assuming because...
Thanks guys! I feel slightly better knowing that my memory probably serves me correct. I can only assume that the previous company I worked for years ago, was more comfortable with the level of losses associated with PVC install than they were with the 'HV dangle' method. Researching a little...
I saw something yesterday that struck me a little weird. Maybe I just don't remember this from when I was a test engineer or maybe the company I'm with now is doing something different. For those of you familiar with Power Line Carrier applications, you know that besides the radio; we use a...
Does anyone remember the old S&C cap bank protection panel? We used to install them on ungrounded cap banks. It was called 'type UP' or 'UV' or something like that. It had the little extender card setup and a pot that you could null out the slop in the neutral over voltage from the RPD.
My...
Thanks, scottf, that makes a lot of sense to me. Most likely someone thinking along those lines a long time ago started doing things this way, and we just have always done it that way ever since.
Thanks again for everyone's feedback.
This may be a stupid question, but it's one of those things that back when I started; it was "always done this way" and I just never questioned it. Back when I was a Relay Test guy, I noticed that all the CCVT circuits were slugged at the safety disco and #10 circuits were run back to the line...
