Excerpt from Voltage Testing of CablesOver-stressing of the insulation is accompanied by a change of insulation resistance and electrostatic capacity.No one factor of safety is applicable to every cable system, but one must consider the conditions of operation as well.In testing, the voltage may be applied: (1) by submersion, (2) between the conductor and metallic sheath, (3) between wires. The submersion test is the most severe. A sine wave is de sirable for testing purposes, but rarely occurs in a commercial generator under these severe conditions of load. Reactance cannot always be used successfully to reduce the volt-ampere load on the generator.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
