3 LKT Technical Data General Remarks FRAKO Power Factor Correction Capacitors described in this catalogue represent a complete prograe of up-to-date technology. We reserve the right to make alterations which are based on newly acquired knowledge or which contribute to an improvement in our products. Technical Remarks For the operation of Power Factor Correction Capacitors three aspects are of utmost importance High overload capacity Long life expectancy Safe reaction at overload FRAKO Power Factor Correction Capacitors are components with a very high power density. This is achieved by a very low loss factor and high utilization of the dielectric. However, in order to attain a high life expectancy, partial discharges (these are negligible electrical discharges inside the dielectric) must be surpressed. This is achieved by using a flame inhibiting mineral filler. Life Expectancy Extreme purity of the material used prevents a deterioration of the loss factor and thereby a reduction of the dielectric strength and the current load capacity. The very low number of failures in the field prove an exceptional high life expectancy up to 170,000 hours. Safety Features FRAKO Power Factor Correction Capacitors offer the highest safety with an overload disconnector, which activates at internal overpressure, disconnects the capacitor from the mains and thereby prevents capacitor destruction. FRAKO carries out type tests and regular random tests to monitor the production safety of this function. The test conditions comply with IEC 831 standards. FRAKO Power Factor Correction Capacitors offer, therefore, the highest possible standard of safety at overload and at the end of their lifetime. Current Load Capacity In networks polluted with harmonics you can expect overvoltages and in particular a higher RMS current load when resonances occur: If, for example, approx. 7 % of the 11th harmonic occurs, then the voltage is 7 % higher; the actual value of the capacitor current, however, is 1.33 times the rated current. For this reason a high current load capacity is even more important than the voltage load capacity. Max. overcurrent up to 2.2 times rated current Max. inrush current up to 300 times rated current Voltage Load Capacity FRAKO Power Factor Correction Capacitors have a load capacity in accordance with EN and -2 as well as IEC and -2.

4 LKT PFC-Capacitors Technical Data Mechanical Construction Cylindrical aluminium case, dielectric consisting of metallized polypropylene foil. Dry type, filled with a flame inhibiting, stabilized mineral filler. The dielectric is self-healing. In case of a breakdown caused, for example, by voltage overload, the self-healing effect takes place. If the self-healing process does not operate (e.g. because of voltage, current or thermal overload) the cover plate, which is designed as an overload valve, is raised and ruptures the internal connecting wires to the coils, so that the capacitor is disconnected from the mains. Design Cylindrical aluminium case, with mounting stud M 12 x 12. All integrated discharge resistor. Single-phase and three-phase types available. Rating kvar; V; 50/60 Hz (higher voltages on request!) Capacitance and Rating Tolerance +/ 5 % Power Loss Approx % (0.5 Watt/kvar) measured at the connecting terminal including discharge resistors. Approx % (0.2 Watt/kvar) measured at the capacitor coils. Temperature Class up to 40 C; + 65 C Discharging According to IEC 831, every power capacitor must have a discharge device which guarantees a discharge to 75 V within three minutes. FRAKO capacitors have integrated discharge resistors which guarantee a discharge to 75 V within one minute. Accessories All capacitors can be equipped with a connecting terminal in tension spring method against surcharge. All capacitors up to diameter 70 can be equipped with a plastic cap and rubber sleeve against surcharge.
