Contact resistance, or CRES, is one of those problems that most engineers prefer not to think about until it’s staring them in the face. For years, it could be managed quietly with routine probe card ...

In a perfect world, electrical insulation would allow no current to flow through it. Unfortunately, several factors can — and will — result in the deterioration and ultimate failure of electrical ...

President, Wyoming Test Fixtures Inc. An important consideration for many composite structures, damage assessment targets two primary components: damage resistance and damage tolerance. Damage ...

Table 100.19 from ANSI/NETA MTS-2011 provides recommended test voltages for proof testing and field testing medium-voltage power circuit breakers and switchgear. These three tests should be in your ...

In the first part of this series on the highs and lows of resistance measurements, I discussed the basic principles for making two- and 4-wire resistance measurements for measuring resistances of less ...

In the second part of this series on the highs and lows of resistance measurements, I illustrated the differences between two-wire and four-wire resistance measurements on an actual low ohmic sample ...
