Transformers, as critical components of power networks, are subjected to various mechanical and electrical stresses under different loading conditions. Their windings may experience minor, recurring ...

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 ...

Power transformers are subject to intense electromagnetic forces during normal operation and especially under fault conditions such as three-phase short circuits or inrush events. These forces arise ...

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 ...

Beckwith Electric's Transformer Protection System M-3311A provides protection, control, monitoring and user interface functions for two, three or four-winding transformers. The system includes ...

Motors and transformers are some of the most reliable pieces of equipment installed at power plants. However, inadequate maintenance can result in trouble. While regular testing and skilled evaluation ...

San Diego, Calif. – Bringing custom planar transformers a step closer to off-the-shelf commodity status, Pulse's PA08XX 140-watt and PA09XX 250-watt series allow DC/DC converter designers to specify ...

A transformer transfers electrical energy from one system to another by induction. Except for grounding and bonding connections, there’s no physical connection between the two systems. For this reason ...

In 1831, Michael Faraday wrapped two wires around opposite sides of an iron doughnut and found that if he passed a current through one, it immediately induced a current in the other. Faraday’s law of ...

Last month's Code Calculations article covered transformer calculation definitions and some specifics of delta transformer calculations. This month we turn our attention to the differences between ...

Growing data center power demands are driving server end-equipment manufacturers to reach higher power-conversion efficiencies in order to reduce the thermal footprint of their systems. The transition ...
