Arcing in conventional OLTCs contaminates oil, increases maintenance, and shortens equipment life. EMR Global’s V-VAC On-Load Tap Changer uses vacuum interrupter technology to perform switching without arcing in oil. This ensures cleaner operation, longer service intervals, improved voltage control, and higher reliability for power and distribution transformers. https://emr.global/on-load-tap-changer-v-vac/
