Transformers are essential devices in the electrical power system that are used to transfer electrical power from one circuit to another through electromagnetic induction. A single-phase transformer is a type of transformer that is used to transfer electrical power in single-phase AC circuits. In this article, we will discuss the 480-volt single-phase transformer wiring diagram.
Introduction to Single-Phase Transformers
Single-phase transformers are designed to transfer electrical power between two circuits that are connected to a common magnetic core. They are commonly used in residential, commercial, and industrial applications to step up or step down the voltage of AC power. They are also used to isolate electrical equipment from the power supply to prevent electrical hazards.
A single-phase transformer consists of a primary winding, a secondary winding, and a magnetic core. The primary winding is connected to the input voltage source, and the secondary winding is connected to the load. When an AC voltage is applied to the primary winding, it creates a magnetic field in the magnetic core, which induces a voltage in the secondary winding. The voltage induced in the secondary winding depends on the turns ratio of the transformer.
480-Volt Single Phase Transformer Wiring Diagram
The 480-volt single-phase transformer wiring diagram is used to connect a transformer that has a primary voltage of 480 volts to a single-phase power source. The transformer is designed to step down the voltage to a lower voltage that can be used by the load. The following is the wiring diagram for a 480-volt single-phase transformer:
| Terminal | Connection |
|---|---|
| H1 | Primary high voltage terminal |
| H2 | Primary low voltage terminal |
| X1 | Secondary high voltage terminal |
| X2 | Secondary low voltage terminal |
Connect the primary high voltage terminal (H1) to one phase of the 480-volt power source. Connect the primary low voltage terminal (H2) to the other phase of the 480-volt power source. The secondary high voltage terminal (X1) is connected to the load, and the secondary low voltage terminal (X2) is connected to the neutral or ground.
FAQs
What is a single-phase transformer?

What is the wiring diagram for a 480-volt single-phase transformer?
The wiring diagram for a 480-volt single-phase transformer consists of four terminals: primary high voltage terminal (H1), primary low voltage terminal (H2), secondary high voltage terminal (X1), and secondary low voltage terminal (X2). Connect the H1 and H2 terminals to the 480-volt power source and connect the X1 terminal to the load and the X2 terminal to the neutral or ground.
What is the difference between a single-phase transformer and a three-phase transformer?
A single-phase transformer is designed to transfer electrical power in single-phase AC circuits, whereas a three-phase transformer is designed to transfer electrical power in three-phase AC circuits. Three-phase transformers have three primary windings and three secondary windings, whereas single-phase transformers have only one primary winding and one secondary winding.
What is the voltage rating of a single-phase transformer?
The voltage rating of a single-phase transformer depends on the application. They are available in various voltage ratings, ranging from a few volts to several hundred kilovolts.
