Abstract
A hot-stick with a selective transformer-penetration tool is described. The tool combination is useful for remote sampling of oil from an energized high-voltage utility transformer without introducing an environmental and maintenance risk. The sample is then independently tested for PCB contamination. The tool used in combination with the hot-stick is selected from among a remote drill chuck provided for drilling a guide hole in the transformer, an impalement spike for enlarging the guide hole, a remote syringe to withdraw an oil sample from the transformer, a remote rivet setter, and a remote caulking gun to close and seal the hole.
