Spark test voltage values given by thepotential difference between the test electrode and the conductor of the coreor cable under test shall be specified in the cable standard 火花试验时,电极与被测试电线或电缆之间的电位差的值在电线标准中有明确规定。
Dc spark testing generates practically no corona and no heat , and is therefore a gentler test process , dc can be used on foamed insulation and thin insulation 直流火花机几乎不能产生电晕和热量?因此它是一种轻微的测试方法?直流火花机可用于发泡和薄的绝缘。
Spark testing is a method of determining the general classification of ferrous materials. It normally entails taking a piece of metal, usually scrap, and applying it to a grinding wheel in order to observe the sparks emitted..
