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 ...

step-down transformers decrease the voltage. The transformer in the diagram above is a step-down transformer – there are fewer turns on the secondary coil than on the primary coil. Type of transformer ...

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 ...

A well-known solution for electrical noise in industrial plants is the constant-voltage transformer, or CVT. These devices can filter distortion and notches from input voltages (see Fig. 1). CVTs have ...

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

Download this article in PDF format. If you search the internet for “transformer equivalent circuits,” you’ll get five pages of over 100 small circuit diagrams. Figures 1 and 2 show two typical ...
