The WA 2293 is a winding analyzer that is optimized for testing three-phase power and distribution transformers. This test set uniquely combines winding resistance measurement, transformer turns ratio ...

Inter-turn short circuit (ITSC) faults are among the most critical and frequent failures in power transformer windings. However, conducting a quantitative analysis of the winding insulation state ...

An autotransformer is a transformer having part of its winding included in both the input and output circuit. A simple autotransformer connection is shown in Fig. 1. Note that because there is a ...

As global energy demand continues to rise, the development of electric vehicles (EVs) has gained significant momentum due to their environmental advantages. Consequently, fast and compact DC-DC ...

Matz Ohlen and Peter Werelius of Megger discuss the unique method of winding resistance measurements in transformers and how they are a fundamental importance to detecting potential mechanical and ...

The use of a copper winding as a temperature sensor is not new. The traditional technique is to disconnect the ac power and the load and to quickly make the measurement using an ohmmeter. But the ...

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 ...

Each turbine in a wind farm is equipped with a step-up transformer, which boosts (steps up) turbine generator output voltage from a few hundred volts to the collector system’s medium voltage ...
