My last two columns covered the topic of voltage troubleshooting as it applies to electrical circuits. An important point to remember is that the majority of service problems are electrically based, ...

Many research and productionapplications require low-level voltage measurements to characterize materialsand devices. When signal voltages approach the microvolt ...

What if a variable-frequency drive (VFD) on a critical system has a fault indication, the “error” LED on a DC power supply has turned on, or a conveyor belt has started behaving erratically — most ...

What consumes more than half of the world's electricity and supports nearly every facet of industrial production? The answer is the AC induction motor. Although these motors typically tolerate ...
