  • Patent number: 8929048
    Abstract: A device for suppressing very fast transients, applicable in protecting electric and/or electric power equipment, and especially transformers operating in electric power substations and in wind power plants, connected in a supply network circuit downstream of a circuit breaker and upstream of the protected equipment is disclosed. The device is a component of an induction character, comprising a high-frequency magnetic core arranged around the current-conducting lead. On the magnetic core is wound at least one winding with at least one pair of terminals used for connecting at least one damping resistor. The inventive device contains an insulating body in which there is a magnetic core, a damping resistor and a winding, or an insulating body in which there is a magnetic core together with a damping resistor, a winding and a section of a current-conducting lead.

  • Publication number: 20090323240
    Abstract: The subject of the invention is a device for suppressing high frequency current or/and voltage components, applicable in protecting electrical equipment, especially against the effects of overvoltage in electrical power networks and stations. The inventive device is characterised in that it contains a series impedance element which is at least one magnetic core reactor (1, 2) whose magnetic circuit comprises at least two active parts on which the reactor windings (3, 4) are wound, which are connected with each other in series and anti-parallel.
