Find Insulation Failures Before They Take the Line Down

Partial discharge is a small electrical breakdown that jumps part of the way across an insulation gap without fully bridging it. Instead of tripping a breaker, it quietly chips away at the insulating material — across a dirty insulator surface, inside a void in a bushing, or off a sharp edge into the air.

Each of those tiny discharges releases a burst of ultrasound well above human hearing. That is what makes the condition detectable: the equipment looks and sounds normal, and often runs at a normal temperature, but it is broadcasting a signature that an acoustic imager can see and locate.

Left alone, the damage compounds. What starts as faint tracking on a switch insulator ends as a flashover, a forced outage, and a replacement on someone else's schedule.

You receive a written report for each site, prepared and signed by the certified consultant who performed the survey. Every indication is presented with its asset ID and location, the acoustic capture, the measured pulse and sound pressure data, the environmental conditions at the time of the reading, and the PDQ Mode discharge classification with its supporting PRPD plot.

The format is built to be handed straight to the people who need it — your maintenance crews, your insurance carrier, and your regulator — as documented evidence of a condition assessment performed on energized equipment.
