摘要： An electric-field meter provided with a housing, an electrode assembly, a shield assembly, a movement assembly, a position detection assembly, a charge measurement circuit, and a leakage current compensation circuit. The electric-field meter can be characterized as a field mill, an induction voltmeter, an electrostatic fluxmeter or an agrimeter. The electrode assembly is selectively exposed to the electric field. The shield assembly alternately covers and exposes the electrode assembly to the electric field. The movement assembly has a source of motive force and a linkage operably connected to one of the shield assembly and the electrode assembly for alternately covering and exposing the electrode assembly to the electric field. The charge measurement circuit receives charge on the electrode assembly. The charge measurement circuit provides a charge detection signal indicative of the charge induced on the electrode assembly as the electrode assembly is selectively exposed to the electric field. A current compensation circuit is provided for offsetting an average leakage current at the input of the charge measurement circuit.

摘要： The invention relates to aspects of a method of registering lightning strikes in the blade of a wind turbine, use of such method, a system of exercising the method. The method according to the invention of registering lightning strikes involve that the method comprises that the lightning strike is captured in a receptor arranged in the blade (5) of the wind turbine, and the lightning current is conducted completely or partially through at least one electric resistor (10), thereby heating it, and that it is registered at least that the temperature of the resistor is or was at some point increased. The heating of the electric resistor, ie the increase in temperature, provides simple and reliable registration. This can be extended to also comprise measurement of the amount of energy contained in the lightning current in a very robust and hence very suitable manner for the task. By the invention it is acknowledged that if a lightning current is conducted through a suitable electric resistor, this will “capture” a share of the amount of energy in the same manner as eg an electric radiator or a furnace, ie the resistor is heated by the current as a function of the voltage and the duration and hence of the amount of energy.

摘要： An active lightning protection system and method is disclosed. According to one embodiment of the invention, the active lightning protection system includes a charge sensor that senses the build-up of charge associated with an imminent lightning strike in the proximity of a structure and a charge source to supply an opposite charge into the proximity to offset the build-up, thereby reducing the possibility of a strike to the structure.

摘要： A deployable lightning protection apparatus particularly suited for use with an aircraft radome comprises; a source of electrically conducting fluid (5); a delivery means (3,4,7) for delivering the conducting fluid to the surface of the radome prior to a lightning strike; a control means (1,2) for controlling the delivery means; and means for directing the conducting fluid across the outer surface of the radome thereby providing a conductive channel for the passage of electrical current resulting from a lightning strike and dissipating said current without damage to the radome. The apparatus allows lightning protection to be deployed in response to a change in atmospheric conditions indicative of a high probability of lightning strike and removed when the danger of lightning strike has passed.

摘要： A lightning rod system including both methods and specific types of lightning rod protection apparatus, which address the need for lightning rod safety features to deter impalement and minimize injury when humans inadvertently fall upon or strike the projecting air terminal through use of a hebetative contagious impact surface (10) on an end cap(s). The system involves lightning rod system components such as humanized quantal rod (3) or coil spring coupler (13) engineered to be responsive within the range of forces achieved when a human of average size and weight falls onto the projecting air terminal from a standing surface level with that on which the lightning rod system is mounted to. The lightning rod system also involves a method and engineered components to retrofit existing lightning rod assemblies. Additionally, the system components address the need for a safety warning air terminal system to prevent impalement and injury from projecting air terminals that are not designed to be conducive to a lightning strike.
