In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

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 ...

When you think of wind farms, images of majestic towers with huge spinning blades spanning the horizon probably come to mind. Designers are not immune to this impulse, as their primary focus is on the ...

When alternating current (AC) prevailed over direct current (DC) in the late 1800s, one of the deciding factors was the need for voltage levels to be raised and lowered throughout the power system to ...

The use of a copper winding as a temperature sensor for transformer windings is not new. But the circuit presented here goes further. It can make the measurement in-circuit and in real time. The use ...

Given that the EU and FDA definitions of what constitutes a medical device encompass a large majority of medical products other than drugs, it is small wonder that the collective term ‘medical ...

TEPCO decommissioned 20 transformers with a service life of between 30 years and 50 years to evaluate the level of deterioration as a result of aging. Transformers are designed with an expected life ...
