What causes "dirty power" and how do you correct it?
We have a Cummins powered generator that powers my data center in the event of power loss.
We recently had a power outage and were planning on using the generator until our local utility provider completed their repairs and restored power. Our facilities manager suggested we do NOT run on the generator because it was discovered the power output was very "dirty" and it may damage our UPS devices, Network Servers, etc. In short, it might damage some/all of my data center equipment!
Can someone tell me what causes a generator power output to be "dirty", and how would one correct that? The generator OBVIOUSLY does us no good if it's power output is that poor!
I'm sure it's also difficult to be accurate, but does anyone have a "best guess" of what it takes and co$t$ to correct this situation.
