Parameters investigated included nozzle distance from the conductor, water pressure, nozzle orifice, water resistivity, and washing technique. Switching impulse tests were performed on nonceramic suspension insulators for the DC Intertie Line. These tests were performed in response to change-out of glass strings to nonceramic while the line is energized. The purpose of the tests was to ensure that the change-out could be performed safely. In particular, the tests were to determine if the withstand voltage of the tower air gaps would be high enough during all parts of the change-out. The withstand voltage should not be lower than an assumed maximum switching surge of 900 kV. The tests were performed on a simulation of the DC Intertie tower, using the setup of hotline tools used by the line crew during the change-out. Tests were then performed on tower conditions in the same steps that would occur in the change-out.<<ETX>>","PeriodicalId":198668,"journal":{"name":"Proceedings of ESMO '93.

This paper describes an attempt to assess the significance of magnetic field dosages received by live line workers during live line operations. The assessment was done by comparing historical dosages received by Eskom's live line workers with insignificant, marginally significant and significant dosages defined by the author. Magnetic field dosages received, was indicated to be significant if the annual magnetic field dosage received by a live line worker approach or exceeds 82,56 mT.h/year. It was shown that the assessed historical magnetic field dosages received by Eskom's live line workers are less than half this value. Only in one case did the annual dosage received approach the marginally significant dosage of 41,28mT.h/year. The assessment, however, is purely speculative at this stage and is not intended for regulatory action.<<ETX>>","PeriodicalId":198668,"journal":{"name":"Proceedings of ESMO '93.

This incident occurred during a complete station outage at a BPA substation. Injuries to the employee consisted of muscle, tissue, and bone damage to one of the worker's shoulders. Tests simulating the accident were performed at BPA's High Voltage Laboratory and at the substation where the accident originally took place in order to determine why the electrical shock occurred and how this type of accident can be prevented in the future. It was concluded from testing and analysis that the injuries occurred to the worker because he came in bare handed contact with a grounded steel structure and a riser that was being welded. In such a situation, the 60 Hz voltage output from the welding machine had the capability of generating enough current to tetanize the muscles in the worker's arms and chest, probably leading to the muscle, tissue, and bone damage to his shoulder.<<ETX>>","PeriodicalId":198668,"journal":{"name":"Proceedings of ESMO '93.
