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 ...

This test set uniquely combines winding resistance measurement, transformer turns ratio, tap changer dynamic resistance, core demagnetization, transformer type detection, magnetic balance, short ...

Omicron’s new Votano 100 is the first voltage transformer testing and calibration system to combine mobility (total weight less than 33 lbs /15 kg) with the highest level of accuracy (precise ...

Remember back…way back, to linear power supplies. Heavy transformers. Big capacitors. As part of my EDN CDEL build, I’ve decided to use just such a power supply as the front end to the two DC-DC PSU ...

(MENAFN- GetNews) Transformers make everything from the power grid to our phone chargers possible, quietly working behind the scenes in almost every device we use. Their magic lies in two key ...

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 ...

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 ...

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.

So there I was with this mystery transformer on which someone put a label showing three different speaker load impedance, but with no indication of what the intended primary winding impedance happens ...
