A VERY FAST TRANSIENT SUPPRESSING DEVICE

摘要

The subject of the invention is a device for suppressing very fast transients (1, 1a, 1b), applicable in protecting electric and/or electric power equipment, and especially transformers operating in electric power substations and in wind power plants, connected in the supply network circuit downstream of the circuit breaker and upstream of the protected equipment. The inventive device is a component of an induction character and it contains a high-frequency magnetic core (2) which is arranged around a current-conducting lead (3). On the magnetic core there is wound at least one winding (4, 4a) with at least one pair of terminals (6) used for connecting at least one damping resistor (7).
