Electrical Aspects of Testing Insulating Gloves

Electrical aspects of testing insulating gloves (used in live line maintenance) are discussed with a major emphasis on the electrical stresses that occur at the water surface near the cuff of the glove. Methods are presented for reducing corona and ozone damage to natural rubber insulating gloves during in-service AC electrical testing. Also, improvements made in AC and DC glove tests show a reduction in the cuff to water line clearance for Class 4 gloves from 15.2 to 7.6 cm, enabling an additional 18% of the glove to be tested.
