Voltage transformers (VT), also called potential transformers (PT), are a parallel-connected type of instrument transformer. They are designed to present a negligible load to the supply being measured and have an accurate voltage ratio and phase relationship to enable accurate secondary connected metering. WebTransformers change the current and voltage passing from one circuit to another. The transformer includes a magnetizable material, called a "core," that connects a primary circuit to a secondary circuit. The primary passes its energy to the secondary through the core by wrapping several times around the ...

WebJun 6, 2024 · The so-called low-voltage transformer refers to the transformer with low load voltage. As long as the load is lower than 600V, it can be called a low-voltage transformer. The low-voltage transformer is mainly composed of primary coil, secondary coil, and a magnet iron circuit. WebA transformer is an electrical device that uses electromagnetic induction to pass an alternating current (AC) signal from one electric circuit to another, often changing (or "transforming") the voltage and electric current. Transformers do not pass direct current (DC), and can be used to take the DC voltage (the constant voltage) out of a ...
