2 LKT General Remarks FRAKO Power Factor Correction s are produced in unique advanced technology and incorporate a triple safety feature. FRAKO is the first capacitor manufacturer who succeeded to combine self-healing capacitor film with segmented film and overpressure disconnection. This manufacturing technique guarantees significantly improved operational reliability of capacitors on power factor correction. 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 s three aspects are of utmost importance: High overload capacity Long life expectancy Safe reaction at overload Overload Capacity In networks where the pollution with harmonics is permanently increasing, surplus loads in capacitors have to be reckoned with. Apart from the higher voltage load it is especially the higher effective current during network resonances, that can considerably further stress the capacitors: Life Expectancy The use of thoroughly tested material as well as careful processing ensures quality and a long life expectancy of the products. FRAKO produces its capacitors according to own specifications, which surpass by far the requirements of EN /2. Quality tests following each single manufacturing step, verify an outstanding manufacturing quality. Combined with a unique capacitor manufacturing technology, FRAKO achieves a worldwide leading durability. For example, the consistently low power loss over many years is achieved by using a special mineral filler and stabilizer which can avoid permanent partial discharges within the dielectric. Vacuum drying and temperature storage over several days avoid oxygen inclusion, which would accelerate the aging process of a capacitor. This means an extra effort in our production which, however, pays-off with a longer life expectancy. Safety Features FRAKO Power Factor Correction s operate with triple safety: Self-healing at over-voltage Reliable in operation because of segmented film An overpressure disconnector disconnects the capacitors from the mains at the end of their lifetime or at dangerous overload. current If, for example, the 11th harmonic is present with 8% of the rated network voltage, the r.m.s. value of the rated voltage is only increased by some 0.3%, but the current in the capacitors will exceed its rated value by 33%. It becomes clear that the ability of a capacitor to withstand excessive current is significantly greater than the ability to withstand excessive voltage. Therefore FRAKO designs its capacitors as follows: Max.overcurrent up to 2.2 times - for the Heavy Duty version: up to 2.7 times - rated current Max. inrush current up to 300 times - for the Heavy Duty version: up to 450 times - rated current Self-healing segmented capacitor film The principle of the overpressure disconnector Patent No

3 LKT To verify the correct functioning of the integrated safety systems, FRAKO regularly draws sample capacitors from the production line. A constantly outstanding quality can be achieved and maintained only this way. Voltage Load Capacity FRAKO Power Factor Correction s have a load capacity in accordance with EN and -2 as well as IEC and -2: Rated voltage [V] 50 Hz Over-voltage [V] 8 hours daily min. daily min. daily min. daily Application FRAKO manufactures four series of Power Factor Correction s: Basic, Standard, Premium and NEW! Heavy Duty. We recoend Basic s for networks with low harmonic content and normal ambient temperature. Standard s are recoended for networks with higher harmonic levels and/or high ambient temperature. Premium s should be used for demanding networks (i.e. networks with very high harmonic levels ans/or very high ambient temperature). Heavy Duty s are recoended for extreme demanding network- and ambient conditions. All four series of capacitors are of excellent FRAKO quality. FRAKO holds the Management System Certificate ISO 9001 and the Environmental Management System ISO Mechanical Construction Cylindrical aluminium case with mounting stud M12 12, low loss self-healing dielectric made from segmented metallized polypropylene film. Filled with a PCB-free, flame inhibiting, mineral filler with adhesive stabilizer and integrated mechanical overpressure disconnector. Permanently connected external discharge resistors at the terminals. The connecting terminal, which is available as an accessory, protects against direct contact of the fast-on terminals and meets the protection class IP 20. Design FRAKO Power Factor Correction s are available as three-phase capacitors in four versions: Basic, Standard, Premium and NEW! Heavy Duty. The singlephase capacitors are available as Standard version. Rating kvar; V; 50 or 60 Hz (other Voltages on request!)

Aprox. 0.2 Watt / kvar dielectric power loss measured at the capacitor coils. Temperatur Class up to - 40 C; + 65 C depending on design Discharging According to EN 60831, 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 50 V within one minute. Accessories for FRAKO Power Factor Correction s All capacitors can be equipped with a patented connecting terminal in tension spring method against surcharge. This connecting terminal ensures a fast, perfect and permanent electrical contact of the connecting wires. All capacitors up to diameter 70 can be equipped with a plastic cap and rubber sleeve to cover the connections.
