This webinar is based on the white paper “Internal Arc & Arc-flash in HV/MV Switchgear”. In the webinar you will learn about:
- The catastrophic effects of internal arc and arc-flash faults
- How to reduce the risks
- Internal arc testing and related worldwide standards
- Design standards and the hierarchy of design measures to prevent internal arc and flashover/arc flash
Using mechanical cable sealing systems helps prevent common causes of internal arc. We will share a successful internal arc testing performed by SATS, the Scandinavian Association for Testing of Electric Power Equipment in Norway, using the Roxtec cable sealing system.
