Epcos capacitors, PhaseCap HD seriesCompact capacitors of PhaseCap series are self-healing capacitors with a film made of a metallized dielectric. Current-conducting metal coating is deposited by metal vapours on one side of the film.The capacitor consists of three single-phase elements encased in one package.Electric contact with armatures is ensured by metal coating on the end surfaces of armature roll.The capacitor elements are connected between phases of a three-phase network. Armatures are placed into a cylindrical aluminium casing and are airtight sealed by press-fitting the metal lid.Dry technology is used in PhaseCap HD capacitors. The capacitor is filled with gas instead of a conventional liquid filling. So there is no risk of oil leakage.Capacitors are capable of self-restoring after overloading. They have touch-safe leads which switch off at overpressure. When used in power factor correction circuits the capacitor undergoes multiple network connection and disconnection cycles. So it is important that the occurring inrush currents do not affect operating efficiency of the capacitor.Great resistance to pulse currents is ensured in the first place by an increased contact area which is a result of an improved metal coating process.The capacitors of PhaseCap series can work with inrush currents which exceed nominal values by 200 times.The capacitors of PhaseCap series cover power range from 40 to 60 reactive kilovolt-amperes with the help of a single capacitor in a ...
