Arc Suppression Coils

Single-phase neutral grounding (earthing) reactors (arc suppression coils) are intended to compensate for the capacitive line-to-ground current during a single phase ground – The arc suppression coil (ASC) represents the central element of the Trench earth fault protection system.

Since the electric system is subject to changes, the inductance of the ASC used for neutral earthing must be variable. The earth fault detection system developed by Trench utilizes the plunger core coil (moveable core design). Based on extensive experience in design, construction and application of ASCs, Trench products can meet the most stringent requirements for earth fault compensating techniques.
