PCS-9705 Bay Control Unit (BCU)

Functions • Measurements of current, voltage, frequency, harmonic (up to 15th), power factor, active/reactive power and energy • Remote/local control of circuit breakers, isolators and earth switch

The PCS-9705 bay control unit is a flexible, easy-to-use control unit used for measuring, monitoring and control of various bays with different voltage levels. The modular architecture, extensive functional library, programmable logic and configurable I/O are ed to meet specific application. It can be optimally tailored for various applications including transmission lines, transformers, circuit breakers, busbars and reactors. The interlocking logic can be configured to promote safe operation by preventing nonpermissible switching operations. IEC 61850-8-1 and IEC 60870-5-103 for station bus, IEC61850-9-2 and GOOSE for process bus are ed.
