Title: Live line insulation sampling

Abstract: A sampling tool is used to collect a sample from the surface of an insulator in a high voltage installation during live line conditions. The sampling tool comprises a sampling head mounted to one end of a hot stick. Sampling cartridges are interchangeably mountable to a pivoted block on the sampling head. The block is biased by a spring to urge the cartridge into contact with the surface of the insulator when a trigger on the sampling head comes into contact with the insulator. One cartridge includes a planing blade for collecting a sliver of material from the insulator surface. An alternative cartridge has a swab and an abrasive pad interchangeably insertable thereon for collecting a material sample from the insulator surface.
