Digitalization is everywhere – on condition that the power flows. Without a reliable power supply, plants, machinery, and buildings cannot be operated, and data processing for analysis, operation control, automation, and many other functions is not possible.
For a secure power supply, it is absolutely necessary to prevent arc faults, or to detect and quench arc faults. Even though they occur very rarely, such events can cause serious damage. In this context, well thought-out concepts and solutions provide the best protection for people, data and assets.
Arc fault – Effects mitigation measures in air-insulated medium-voltage switchgear
The occurrence of an internal arc fault in a well-designed, type-tested, correctly installed, and operated switchgear is improbable – but not impossible. Potential consequences of arc flash incidents on medium voltage switchgear and available active measures with their effects on the availability of the electrical equipment will be presented.
