Why not Save Money, Save Lives, and Save Aggravation?

by installing Arc Flash preventing transformer in the first place.
This is how an auto-parts manufacturer improved up-time in a CNC machine facility. In this test, one CNC machine's Voltage Harmonics went from 7% to 1%. One AFPT was installed in place of each Delta / Wye Transformer. Problem Solved!
These machines were faulting, causing the CNC control, PLC control Operator Station Computer and the drives to lock up every day.
Maintenance electricians disconnected the power feed from the Delta - Wye transformer (Before) and connected it to the Delta - Delta power transformer which had a Phaseback VSGR on the secondary. (After) = AFPT Arc Flash Preventing Transformer.
The results were very conclusive and very surprising to the plant operations people. They went from faulting multiple times per shift to never faulting. Up-time, in the plant, went from 50% to 85% so the factory did not have to ship parts out for machining and they saved $9.00 per part. 33,000 parts per month saved $297,000 per month. That was a payback in less than one week. Install AFPTin the first place, so you can Save money, Save Lives, and Save Aggravation.

Harmonics related Power Quality events affecting Power Systems can cause downtime. Solutions
Drives /Rectifiers cause Harmonics Tuned Capacitors or AFPT
Grnd Current costs money continuously Reactor or AFPT
Fundamentally improve your power system, continue to operate, rather than fault and replace damaged equipment.
Replace your distribution transformers with AFPT and eliminate SPDs, Harmonic Filters, Voltage Regulators, NGR or HRG,
