DCR – Automatic power factor controllers

Schema02

Graphic display

Reducing the absorption of reactive energy from the mains delivers immediate cost savings, reduces losses from dissipation along power lines and also slows down the ageing of the power lines themselves.
Most Authorities for Electricity impose strict limits for reactive energy. They also impose penalties for failing to respect requirements and even permits the suspension of supply.

Integration with synergy

Power factor correction systems are essential in industrial applications using solar power, where the absorbed reactive power remain constant, while the absorbed active power drops when it is supplied by the solar source. Under such conditions, power factor correction systems help to maximise return on investment.
Remote supervision of power factor correction panels using DCR series automatic power factor controllers connected to synergy via¬†EXP… communication modules, makes it possible to verify system state in real time, optimise the planning of system maintenance, and verify residual capacitor power and the number of connections made by the switches.
