ARC PROTECTION SET. SDI 3143.2 FOR TRANSFOMERS

The current-limiting protection on the transformer cover achieves the same benefits as the current-limiting protection on PAS and BLL conductors. The number of short circuits (pjk) is significantly reduced compared to the previously recommended spark gap protection—and a wear-free, thus maintenance-free, protection method is achieved. Ensto has renewed the product lineup of current-limiting protections for small transformers (under 200 kVA). In the updated lineup, ease of use has received special attention: This product description is an automated translation of the original Finnish description.
