ABSTRACT:
A sparking device, in one aspect, includes first and second electrodes for coupling with corresponding first and second electric potentials. The first electrode includes an elongate member having proximal and distal parts. The second electrode includes a body receiving the proximal part. A first insulation portion electrically insulates the proximal part of the elongate member from the body. The first electrode includes an end member connected with the distal part of the elongate member. The end member includes a first section with a plurality of first electrical contacts offset from a longitudinal axis of the device. The body includes a second section with a plurality of second electrical contacts offset from the longitudinal axis. A plurality of sets of the first and second electrical contacts provide a plurality of gaps for sparking between the first and second electrodes, wherein a difference provided between the first and second electric potentials serves to cause sparking across at least one of the gaps. A second insulation portion is disposed between the longitudinal axis and at least one of the gaps to form a drainage path section, wherein the drainage path section serves to promote avoidance of short-circuiting between the body and the distal part of the elongate member and/or the end member during exposure of the device to precipitation.
