Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

In a world of tight timelines and ever-increasing performance requirements, it’s critical to create circuit designs right the first time; thus, engineers in the analog and mixed-signal industry often ...

With the new MCT1605 test set from Megger, comprehensive testing of current transformers – including multi-ratio types – can be carried out quickly and easily. With a single push of a button, the ...

In this article, we discuss the basic operation and design of a Fly-Buck™ converter. This discussion also includes a detailed explanation about the control and regulation of this converter. The ...

So you have an old tube-type transmitter as a backup. It ran perfectly when you last turned it on two years ago to substitute for your then-ailing solid-state main transmitter. Now you need it again.

In response to the growing demand for compact substation test systems that are capable of performing a wide range of tests, Megger has developed TRAX test sets. Combining versatility with ease of ...

Electrica signature analysis (ESA) uses the magnetic field in the air gap of an electrical machine to evaluate power quality conditions. Dry and oil transofrmer types are subject to problems ...

I’m sure many readers would question why anyone would want to perform a relatively expensive insulation power factor test on an inexpensive transformer. Typically, if any testing is done, it will be ...

Using a flyback topology to generate a high voltage is a common approach. The voltage can charge a capacitor for a high-energy pulse. Such an approach is used in defibrillator capacitors, photoflash ...
