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 ...

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 ...

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.

Among the various diagnostic methods used to assess transformer condition, capacitance and Tan Delta testing has gained broad acceptance as an effective means of evaluating insulation health. By ...

Complex grids depend on equipment such as transformers, protection relays, switchgear, and cables—each of which can develop faults not immediately visible during normal operation. As a result, ...

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 ...

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 ...

High Voltage, Inc. is an American test equipment manufacturing company located in rural Copake, New York. The company’s HPA line of ac testers are available with outputs up to 300 kV ac and power ...

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.

ZHUHAI, GUANGDONG, CHINA, January 21, 2026 /EINPresswire.com/ -- Environmental responsibility has transitioned from ...

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 ...

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 ...
