Partial discharge is more common than we like to believe. There are ready technologies available that help to not only reduce the risk of arc flash exposure but also simultaneously enhance the overall reliability of the electrical system. Its really a win-win for safety and reliability. There are a few technologies available, but some are better than others. Some are suited for a particular purpose. It’s a case of choosing the right technology, for the right applications, on the right components, on the right situation.
When compared, ultrasound seems to be the most practical, simple, comprehensive, and cost-effective. Ultrasound should be your first line of defense technology to build out your overall electrical condition monitoring and analysis strategy.
