Since a couple of members have had trouble with their Phase Perfect feeding high voltage into their home electrical service, and Phase Perfect has not offered a solution, is there a way you could make something to automatically shut down the Phase Perfect in the event of a failure?
Yazz. Out of my "Hell box", actually. Couple of the Mercury-displacement relays part of my approach to a rapid-isolation fix so that even IF the P-P is too damaged to RESPOND to a control input, it is cut-loose, load AND supply end. Already do this with my "4Q" (regenerative) DC drives, line-side only being "good enough".
That said, such "health monitoring" and protection goods certainly exist as ready-made.
Telco's and IS/IT data center facilities have a "critical need", what with sometimes TWO separate utility company feeds, more than one gen set, and split battery plants for multiple UPS. Some two-dollar component fails, it is just NOT meant to take major banks and such offline, etc.
So... it would be better by far to
buy it, "rated for the task" and "to meet code". Inch-hoorance issues as well as common-sense and actual-not-theoretical safety.
Beside, most of y'all's JOB as pays the bills is making "stuff" OTHER THAN electrical switchgear anyway.
I've just been twigged to the need/benefit of having such, unusual or no - and have not yet researched what is in the market.
Get enough "PM Eyes" onto most any problem, and solutions WILL be found!
Thanks for starting the thread!
