arc-suppression coil

[¦ärk sə′presh·ən ¦kȯil]
(electricity)
A grounding reactor, used in alternating-current power transmission systems, which is designed to limit the current flowing to ground at the location of a fault almost to zero by setting up a reactive current to ground that balances the capacitive current to ground flowing from the lines. Also known as Petersen coil.
