Fast earthing switch solar container electrical equipment

How does ultra-fast earthing switch tripping work?

The tripping of the Ultra-Fast Earthing Switch first requires the rapid and reliable detection of an arc fault in a defined protection zone of the switchgear system. The specific fault is detected either by external arc fault detection systems which are combined with a UFES electronic tripping unit of 1. UFES PSE 2.
