The paper presents the information reported during the ESMO-90 panel session, entitled "Rationale for Test Criteria,, o f Live-Line Maintenance Protective Equipment . The paper discusses the rationale for electrical testing of live line maintenance tools, in particular, the Insulating Protective Equipment, (IPE), like insulating blankets and line hoses. The present status of such testing is compared to the existing standards. The main thrust of the paper is the presentation of test results from a special international test program involving ten laboratories. Data are given on the breakdown voltage correlation between power frequency, direct current and switching overvoltage tests. The results indicate that the equivalence in testing between power frequency and DC, and power frequency and switching overvoltage now used in the industry and standards may be incorrect.Kevwords : Insulating Protective Equipment, electrical testing, live-line maintenance, safety.In cooperation between IEC-TC 78 and IEEE ESMOL Subcommittee, a special test program was set up to establish a correlation between power frequency, switch-

The purpose of this paper is to present the results of puncture breakdown tests on rubber gloves.A positive polarity switching surge voltage (275/2500us), or a 60 Hertz alternating voltage was applied to the glove to cause breakdown. The effect of mechanical pressure on glove breakdown behavior, and the influence of using a leather protector were investigated. It is believed that the results obtained will help to determine the operating limits and reliability of the glove insulation.
