Live-line tool (hot stick) tester

Data records

  • An alternating-current hipot test set with a guarded leakage-current measurement in the return leg also tests the insulating booms of aerial work platforms and bucket trucks, a test for which ANSI/SIA A92.2 gives the specification. Source: Hipotronics product page, web page edition. Verified 2026-10-27. Record instr.live-line-tool-tester.aerial-lift-testing
  • The readout is leakage current under guarded metering, with the peak value held; the guard keeps stray and surface leakage of the electrode arrangement out of the measured current, and the test voltage is applied per section of stick length. Source: Von Corporation product page, web page edition. Verified 2026-10-27. Record instr.live-line-tool-tester.guarded-leakage-readout
  • Live-line tools are wiped clean and visually inspected before each day's use and are removed from service periodically for examination, cleaning, repair and a wet test; the maker electrically tests the foam-filled pole at the factory.

  • A portable wet/dry tester is placed on the stick and moved along it in overlapping positions, then the stick is turned a quarter turn and the pass repeated until the full circumference has been covered; stray currents through the air and inside the tester are zeroed out before the stick is introduced, and a check bar drives the meter to full scale to confirm that the tester works.

  • A live-line tool tester applies a high voltage along a hot stick and reads the leakage current through or over the fiberglass-reinforced plastic, revealing surface contamination, absorbed moisture and internal conductive paths such as carbon tracks that visual inspection cannot find.

  • A shop tester for several sticks wraps electrodes around each stick as it is loaded, alternating high-voltage and return electrodes at fixed intervals along the length so that each section is stressed and metered separately; a failing stick stops the test with an audible signal and the failed position is indicated.

  • A tool is tested dry and then wet, the wet test being made after the tool is lightly misted with distilled or deionized water; silicone or wax applied to the surface can fill scratches and voids and produce a false pass on the wet test.
