The last word in power factor control
ABB has designed its new RVT power factor controller as the "ultimate" controller for the flexible monitoring and switching of capacitor banks in power factor control applications.
ABB has designed its new RVT power factor controller as the "ultimate" controller for the flexible monitoring and switching of capacitor banks in power factor control (PFC) applications The key features of the RVT include easy commissioning and automatic setup, 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

Filter increases safety and cuts neutral currents
ABB's new PQF-T active filter can reduce the risk of cables overheating and overloading, as well as increasing energy efficiency.
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); and 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 undervoltage, overtemperature and excessive harmonic distortion.
The standard RVT has the facility to trigger external alarms, whereas 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 building management system.
The RVT is suitable for use in a wide range of ambient temperatures from -20 to +70C and its flexibility is increased even further by multilanguage support which allows the operator to select its working language from a choice of English, French, German and Spanish.
The RVT can be connected to voltages in the range 100 to 400V AC at 50 or 60Hz and it will work with both 5 and 1A current transformers.
