ABB Power - RVT – The Ultimate Power Factor Controller

Power Factor Controller - Power Quality - Power Factor Correction


ABB’s RVT power factor controller is the ‘ultimate’ controller for the flexible monitoring and switching of capacitor banks in power factor control (PFC) applications. It features easy commissioning and automatic set-up, a user-friendly menu-based operator interface with a full graphics display, and a highly efficient switching strategy that combines integral, direct and circular switching.

The RVT provides comprehensive measurement, monitoring and event-logging of network and capacitor bank information including: active and apparent power; reactive power; voltage and current; temperature; total harmonic distortion on voltage (THD V) and total harmonic distortion on current (THD I); frequency.

Programmable parameter setting enables the operator to set the switching strategy, with the flexibility to determine different control targets for day and night operation, and to enter alarm thresholds to protect the capacitor bank against such events as over and under-voltage, over-temperature and excessive harmonic distortion.

The standard RVT has the facility to trigger external alarms, while the RVT-Modbus version is fitted with an RS485 Modbus adapter which makes all its operational parameters accessible and downloadable for full integration within a BMS.
