WebAug 1, 2000 · Basically, you're applying a voltage (specifically a highly regulated, stabilized DC voltage) across a dielectric, measuring the amount of current flowing through that dielectric, and then calculating (using Ohm's Law) a resistance measurement. Let's clarify our use of the term "current." We're talking about leakage current. WebFlanges are designed to remain leak-free under hydrostatic test pressure when cold and under operating pressure when hot. The …
