FRAKO Reactive Power Control Relays
These reactive power control relays can be employed universally; they adapt themselves automatically to the power factor correction system to which they are connected and to the network requiring this correction. The patented control characteristic curve regulates cos phi to the selected target value and avoids overcorrecting under light load conditions. Charges for reactive power demand are therefore reliably eliminated and the risk of network disruption is reduced.
- High accuracy and sensitivity even in networks heavily contaminated with harmonics
- Detection of power fed back into the supply in networks with their own generating facilities
- No undue stressing of the components of the power factor correction system in operation
- Increased service life expectation for the system
The innovative patented control characteristics fulfil the requirements of present-day industrial networks, making the FRAKO control relay universally employable.
