C70 is an integrated protection, control and monitoring device for capacitor banks based on the well-established and proven UR relay platform of GE Multilin. C70 provides both the bank and system protection schemes for shunt capacitor protection. The current and voltage-based protection functions are designed to provide sensitive protection for grounded, ungrounded single and parallel capacitor banks and banks with taps, for a variety of capacitor bank configurations. Combined with the sophisticated built-in control functions turn ON/OFF banks with relative ease and flexibility for automatic voltage regulation.

Reduce investments in lifetime costs, engineering, installation and commissioning by using a product with integrated protection, control, automation and monitoring feature for shunt capacitor bank protection in one easy to use package.
