This is probably right up a lot of your guys alley.
We've recently moved in to a new facility for our company (yay for massive unplanned company growth!) and much to my surprise, our 240v 3ph service is an ungrounded delta. I've only ever read about ungrounded service, I've never experienced one hands on. REALLY weird not having a ground reference and logging A phase to ground throughout the day and seeing readings vary from 365v to 90v. When we originally toured the place, I assumed it was a 240v 3ph center tapped delta. I was wrong. Oops. Anyhow..
The service for us, as well as two other tenants is off of a trio of 100kva cans that split between us. I'm not really thrilled about this, since if one tenant has a fault, it immediately becomes our problem as well. Shockingly, there is no ground fault detection in our facility, nor the company behind us.
So I need a recommendation.
I came across this module from ATC; https://www.marshbellofram.com/diversified-electronics/products/gfd-series-ungrounded-systems-alert/ but I'm looking for something at least with a relay output so I can connect a audible and visual indicator to it.
