These capacitors are self-healing and extremely durable. The capacitance remains practically unchanged over a long period of time which is of particular interest for applications with tuning or detuning reactors; domino-like failures of entire groups of series-connected capacitor elements and the resulting phase asymmetries are practically impossible. Moreover, the capacitors are completely insensitive to vibration stress.
Unlike traditional ALLFILM-capacitors, MSD™ is manufactured without liquid impregnants, and filled with solid, plant-oil-based resin. Other than with conventional ALLFILM-capacitors, the integrated pressure switch provides real and reliable protection in the event of a fault.
Available as three-phase designs (WYE) in the range from 50 to 300kvar, for mains up to 12kV.
