PURPOSE
This dielectric test is performed for the purpose of determiningthe ability of component parts to withstand a potential at sealevel or at a specified altitude. The potential used is normallyabove rated voltage and simulates momentary overpotentials due toswitching, surges, and other similar phenomena. AIthough this testis often called a voltage breakdown or dielectric strength test,the intention is not to cause a breakdown of the insulation of todetect corona, but to determine whether insulating materials andspacings in the component are adequate. If a specimen is faulty inthese respects, application of the test voltage will result ineither an air, surface, or puncture discharge.
