Surge capacitors are used to protect valuable equipment from the damaging effects of voltage transients. Typically, these specially designed capacitors are combined with a non-inductive resistor and are also described as RC transient suppressors. EPCOS surge capacitors use oil impregnated hazy bi-axially oriented polypropylene film as the dielectric and edge folded aluminum foil as the electrode. They are characterized by low losses, high surge handling capability and reliability. These capacitors are specifically designed for this application. They are based on a power film capacitor technology with a proven field performance. Surge suppression capacitors offer ideal protection for MV assets that can be damaged by transients. Typical applications include generators, motors, transformers or reactors.
