Coupling Capacitors / Capacitor Voltage Dividers – Type CCU

Coupling capacitors are used in high voltage system for power line carrier coupling purposes.

Capacitor voltage dividers are used high voltage networks to provide low voltage signal for Power Quality Measurement purposes.

Both coupling capacitors and capacitor voltage dividers single phase post type units which share well proven design and technology with capacitor voltage transformers. They are designed with exceptional longevity and reliability, aiming for at least 50 years of service life.
