The PVX-4150 pulse generator produces fast, high voltage waveforms to 1 500 V. Optimized for high impedance capacitive loads, the PVx-4150 is well suited for driving extraction grids and deflection ...

A PQ expert can link an abnormal current or voltage waveform to an abnormal condition on a power system just as a handwriting expert matches a signature to a person. Many facilities now have online ...

At one time, almost all electrical loads were linear — those that weren't made up such a small portion of the total that they had little effect on electrical system operation. That all changed, ...

Common traits of digital multimeters (DMMs). Classifying DMMs by their amount of digits. What role do digitizers play in making voltage measurements? Measuring voltage may be the most basic ...

Variable frequency drives (or VFDs) are widely used throughout industry to provide adjustable speed control of ac motors. Although modern versions are relatively simple to install and operate, VFDs ...
