Over the past two years I have been doing commissioning work with Siemens and ABB. Typically they hire my company to do the apparatus testing for the GIS, voltages 69KV - 500KV. Does anyone have expierence with Power Factor testing this equipment, or is this unique to the utility having these installed?
