Power Factor Correction Capacitors

Low Voltage Power Factor Correction Capacitors

The application of low voltage Power Factor Correction Capacitors is for the purpose of improving Power Factor in low voltage power networks. Our capacitors us an MKP technology that consists of metallized polypropylene (PP) film that has an extremely low loss factor. The dielectric system is self-healing and has no liquid impregnate. Capacitor elements are enclosed in cylindrical aluminum cases and are filled with a vegetable oil based gel which is non-toxic, biodegradable and environmentally friendly.

Our power factor correction capacitors have over-pressure protection to disconnect it from the supply in the event of internal failure and at the end of its operational life.

Over-pressure protection

Three phase capacitors are delta connected. Delta connected three phase capacitors are friendlier to the electrical environment than others (i.e. Wye connected). They not only provide capacitance to each phase but also provides no voltage unbalances.

If a capacitor cell should fail for any reason in one phase it will move from a closed delta to an ope delta configuration. In this instance the voltage on each phase stays the same. Failure of a capacitor cell would only mean a drop in the kVAR on the circuit. In other words, a 30kVAR delta connected three phase capacitor with a failed cell would provide 20kVAR to the electrical system instead of 30kVAR.

Delta connected capacitors are also capable of circulating harmonic currents to some degree within the delta circuit and by doing so help to reduce the harmonics on the electrical system.

Power factor correction capacitors can be installed in any position. Mounting is by M12 stud on the bottom and this can also be used for the earth connection - max tightening torque 5 Nm. Connection in terminal is done by M5 screws - max torque 2 Nm. Connecting cables must permit the capacitor top to rise by 20 mm to ensure correct operation of the overpressure disconnector. Expansion upper part of the capacitor must be free without any fixing clamp. If necessary, fixing clamps can be mounted on the lower capacitor part below the groove only.
