The circuit was designed to provide a means for measuring the operating voltage of zener diodes before applying on a circuit. Zener Diode – a special kind of diode that permits the flow of current in ...

This simple circuit tests speakers, microphones, transformers and voltage. It’s basically a very low frequency oscillator that produces extremely short ‘fruity’ pulses. The type of sound produced is ...

I see techs in the field get the most frustrated when they have a low-voltage short they can’t seem to locate. The challenge techs face with low voltage diagnosis is a combination of poor process and ...

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 ...

For product safety testing, the basic instrument for many years has been the dielectric voltage withstand or high-potential (hipot) tester. But like so many other instruments that must deal with today ...

AVTs help reduce the risk of exposure to electrical hazards and improve worker safety by automating and simplifying the process of verifying the absence of voltage. The importance of creating a safe ...

If a poll was taken to determine what aspect of the hot rod hobby enthusiasts dislike the most, there’s a high likelihood that “diagnosing electrical issues/gremlins” would be the popular answer. An ...

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 ...
