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 ...

With the automated six-winding test function provided by Megger’s new MTO3XX transformer ohmmeters, resistance measurements can be made on all phases and windings of a power transformer without the ...

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

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 ...

AI and Machine Learning can predict transformer faults by analyzing dissolved gas data, thermal patterns, and vibration ...
