Had 2 customers do it here in NY/NJ and someone else in FL. Not mining related, just manufacturing
Saved them a lot.
BUT:
1) Everything is 'your fault' not the fault of the power company until you can prove otherwise when it comes to low power issues. 3 states, 3 different power companies, same BS.
2) If you do have issues they will not even test TO the transformer without your electrician being there.
3) If you do need parts / repair you can be down for a while. Unless you have a spare $50k transformer sitting around like the power company does.
For my customer that had a lot of issues it was stressful and annoying, but they could function on a limited bases.
A mining facility is going to be off....

#1: What do you mean by "low power issues" ?
#2, who won't test the transformer?
thanks for the advice
low power issues would be the transformer you have say a 500kva that should put out 240 volts is doing 201 volts.
You will need to test the transformer with your guys not the power company guys.
you will need to swap in a spare with your guys .
