In order to determine the effect of such exposure, high-voltage laboratory tests were performed to evaluate the maximum leakage-current on the hot stick surface. A test program was set up in which the hot sticks were exposed to atmospheric pollution at two Hydro-Quebec substations and tested at the IREQ HV laboratory. The tests included salt deposit density (SDD) measurements, leakage-current measurements during high-voltage tests, flashover tests, resistivity measurements of collected-water, etc. The results identified several parameters describing the relative pollution level at each substation. A specific high-voltage leakage-current test highlighted two interesting aspects: the maximum RMS alternating current, under a specific set of parameters (e.g. hot stick test length of 1 m, test voltage of 30 kV, salt fog resistivity of 30 /spl Omega/.M), combined with the deposit of natural atmospheric pollution on the hot-stick surface; the behavior of hot-stick fiberglass treated with silicone or wax, exposed to salt fog of a given water resistivity level.<<ETX>>","PeriodicalId":198668,"journal":{"name":"Proceedings of ESMO '93.

There were requirements and restrictions imposed upon PG&E for issuing and maintaining this variance permit. One such requirement was that PG&E institute a program to evaluate and monitor the magnetic field health issue as it relates to the use of barehand techniques. The intent was to compare the electromagnetic exposure levels of barehand work procedures to other hot stick, live line techniques that PG&E utilizes. As part of the monitoring program and information gathering process, the Pacific Gas and Electric Company's Joint Union/Management Barehand Committee requested that electrical characteristic tests be performed on the arc that is obtained when performing the procedure of bonding onto or removing the bonding connection from an energized transmission line conductor. The purpose of the test was two-fold: (1) to characterize the energy in the bonding arc as defined in terms of power density, and (2) to compare measured arc power density levels with the protection guideline limits established in American National Standard Institute (ANSI) C95.1-1991 Standard \"American National Standard Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields (300 kHz-100 GHz)\".<<ETX>>","PeriodicalId":198668,"journal":{"name":"Proceedings of ESMO '93.
