A thorough understanding of Delta and Wye service transformers, their primary and secondary windings, and their windings’ voltages, will help HVACR service technicians in their understanding of ...

Voltage transformers (VT) are used in electrical grids for metering and/or protection purposes. The high requirements regarding their precision demand a calibration ...

In the field of electrical engineering, a power system is made up of several pieces of equipment and one of them is a transformer which is the most crucial part of the whole system, the same as a ...

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 ...

Have you ever wondered why some low-voltage (115-V) power-consuming devices burn out too often? It could be because they are wired to the “high” or “wild” power leg of a voltage supply. These devices ...

This application note presents the application and specification of signal transformers. It also describes the basics of wideband transformers and autotransformers, and its design equations. This ...

A resolver is an electromechanical transducer that converts shaft angle to an absolute analog signal. Extremely rugged, it can be mounted anywhere an angle (down to 0.1 arcminute) needs to be measured ...

Thousands of ready-made off-the-shelf transformers out in the market are available to be designed into electronic or electrical circuits. However, when the right part just can’t be found, you may want ...
