Energy sector Power Factor Correction Equipment

PFC Capacitors for Low Voltage type KNK Applications The KNK capacitors are used for power factor correction of inductive consumers (transformers, electric motors, rectifiers in industrial networks for voltages of up to 1000 V. sealing washer Design ISKRA KNK Capacitors are constructed by the MKP sistem of low-loss, metalized polypropylene films with a special metalization, whose purpose is to favour the self–healing process and reduce dielectric losses. On the end of the element is zinc metal sprayed to make continuous good electrical contact with electrode metalization on the electric. Three...

PFC Capacitors for Low Voltage type KNK Discharge Resistor Capacitors should be discharged to < =10 % of the rated voltage prior to being re-energized. KNK capacitors are equipped with a resistor that discharges the capacitor to 75 V under 3 min. Over-Pressure Disconnector Every capacitor is protected against breaking by the overpressure disconnector, which ensures safe disconnection of the capacitor from the network in the event of overloading and at the end of its operational life. interupted wire

PFC Capacitors for Low Voltage type KNK ELECTRICAL CONNECTION Connections to the capacitor terminals must be made with insulated flexible copper conductors. Conductors must have a proper cross section for expected capacitor currents including overloads. Conductors have to be equipped with end sleeves or cable lugs in case of screw terminals. When coupling the capacitors in parallel do not exceed the maximal current per contact. Do not solder leads to the terminals. Check connections periodically to avoid weak connections and overheating of the connecting points. With our 16 and 25 mm2 terminals...
