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 ...

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.

Omicron has developed a portable three-phase test system that supports all common electrical tests on power transformers. Weighing just 20kg, Testrano 600 is suitable for routine and diagnostic ...

When you’re testing or debugging some mains-powered gear, plugging it directly into the outlet can often be an exciting proposition. If such excitement is not really your thing, you can opt for an ...

As part of a power electronics design project involving a 3.6-V dc-dc converter, it became necessary to test and accurately characterize the planar transformer shown in Fig. 1. Transformer operating ...

Testing products designed to operate from ac power is not as simple as one might think. Consider a factory with the straight-forward need to manufacture and test the heating element for a toaster.

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 ...

An AC resonant test system is designed to generate high alternating voltage by forming a resonant circuit between the reactor and the test object. By operating at or near resonance, the system can ...

Transformers are very reliable devices and can provide service for a long time if regularly maintained and serviced. They’re also the single most costly item in any substation. To protect against ...
