According to one implementation of the present disclosure, a method for field destabilization is disclosed. The method includes detecting, on or proximate to one or more aerial surfaces, a presence of an electric-field above a predetermined threshold; positioning the one or more antennas towards the one or more aerial surfaces; and transmitting electromagnetic waves towards the one or more aerial surfaces.

According to one implementation of the present disclosure, a method is disclosed. The method includes: detecting, on or proximate to one or more surfaces of an aircraft, a presence of an electric-field above a predetermined threshold; and in response to the detection, activating one or more beam sources to generate an ionized column of charge away from the aircraft.

The present apparatus, system and method solves the problems of the prior art by enabling substantial dissipation of an electrical energy surge coming from communications antenna which has been struck by lightning. The apparatus is for mounting to an exterior of a building at or near communications antenna also located at the exterior of the building. The apparatus is connected with incoming coaxial cables extending from exterior mounted antenna and with outgoing coaxial cables which extend from the apparatus to communications equipment housed within a communications center. The lighting strike surge travels from antenna, along the incoming coaxial cable and is redirected within the apparatus by polyphasers which trip at capacity to redirect the surge to three separate grounding bars and prevent the surge from continuing along outgoing coaxial cables leading to communications equipment thus safely dissipating surge and shielding communications equipment.

A lightning diverter system is disclosed including an outer rod having a first outer rod segment, a second outer rod segment, and a housing cabinet; and an inner rod having a first inner rod segment and a second inner rod segment. The second inner rod segment is in attachment with the second outer rod segment. The inner rod and the outer rod are concentric and configured to move between a rod extended configuration and a rod retracted configuration. A conductive break is in attachment with the outer rod and the inner rod. The lightning diverter system further includes a sensor configured for monitoring an environmental parameter and sending a first signal to a processor configured for determining if the environmental parameter fails satisfy an environmental parameter threshold and sending a second signal to move the lightning diverter system between the rod retracted configuration and rod extended configuration.

Systems and methods are disclosed to detect cloud-to-ground (CG) strokes that include and/or are followed by continuing current (CC). For example, earth-based lightning data may be generated for one or more lightning pulses detected in an environmental space using multiple earth-based lightning detection sensors. Space-based lightning data may be received for one or more optical signals detected in the environmental space using one or more space-based lightning detection sensors. It may be determined from the earth-based and space-based lightning data whether a lightning pulse is a CG stroke that includes or is followed by CC. Charge transfer of a CG stroke with CC may be obtained from measurements of electromagnetic fields by an array of electromagnetic field sensors to generate training data. A machine learning model may be trained to relate space-based and/or earth-based lightning data to charge transfer where there is no proximate array of electromagnetic field sensors.

Aspects of the subject disclosure may include, a system that facilitates detecting a transient electrical signal on a transmission medium that facilitates propagation of electromagnetic waves induced by the waveguide system and generating signal data associated with the transient electrical signal. Other embodiments are disclosed.

A wind turbine (10) is disclosed having a hub (14) with electrical power therein and at least one blade (20) attached to the hub. The blade (20) has a blade root (21), a blade tip (26) and a down-wire (30) for the conduction of lightning current to the ground. The wind turbine (10) further has a blade electrical system (99) that takes electrical power from the hub (14) and transmits electrical power into the blade (20) to at least one area located between the blade root (21) and the blade tip (26). The blade electrical system (99) if formed by a power-transfer unit (100) having a power-driver unit (110), a power-conditioner unit (130) and a dielectric (120) separating the power-driver unit (110) and the power-conditioner unit (130). The power-driver unit (110) receives electrical power from the hub (14) and transmit the electrical power through the dielectric (120) to the power-conditioner unit (130).
