The Founders

Prüfentronik LLC was founded in 2023 by Austin Richards and Ezekiel Bierschank. We are engineers and entrepreneurs. We are passionate about helping the electrical utility industry improve safety, and our mission is to create affordable tools to quickly detect destructive corona discharge on transmission lines and distribution equipment.

The Product

We chose to focus exclusively on providing corona detection tools that our end users can use to detect corona discharge and save time, labor and money by spotting and remediating minor problems before they turn into to hazardous issues. Our products detect the very faint shortwave ultraviolet radiation emitted by corona discharge using single-element detectors that are positioned behind focusing optics that define the field of view of the sensor device. Our devices operate in the shortwave ultraviolet band just as corona cameras do. This is in order to eliminate false readings from sunlight, since the amount of shortwave UV solar radiation at ground level is vanishingly small.

The Factory

Our offices are located in Santa Barbara California and Portland Oregon. All of our product design, product testing, engineering, and manufacturing takes place in the United States of America.

The Cause

We’re a small independent American business committed to the design and manufacturing of lower-cost inspection tools to help save lives, property, and ecosystems through early detection of destructive corona discharge on high-voltage power equipment. Affordable corona detection sensors will be deployed more widely than corona cameras, and will catch more problems early on.
