So you have power circuit breakers at your facility, and they seem to be just fine, sitting there quietly doing their job. What you may not realize is that even though your circuit breakers are ...

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 ...

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 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 ...

When a voltage is applied to a material or device,current will flow through it. How much current will flow is based on theresistance that the material applies to a circuit. The resistance of a ...

InfraTec and Volkswagen Sachsen have been working together since 2007 on non-destructive methods for quality assurance in car ...
