capacitor banks protection

The 7SR191 Capa devices are numeric protection relays designed for application on shunt connected distribution capacitor banks arranged in all common connection configurations, typically single star, double star, delta or in an H configuration. These relays provide all protection functions required in a single device. Relay versions which can be connected to primary voltage transformers provide additional voltage protection functions and metering. The 7SR191 relays are developed from the proven 7SR11 & 7SR12 Argus family of products providing a familiar product using the latest generation of hardware technology. Housed in a 4U high, size E4 case, these relays provide protection, monitoring, instrumentation and metering with integrated input and output logic, data logging & fault reports. Communication access to the relay functionality is via a front USB port for local PC connection or rear electrical RS485 port for remote connection.
