What Does a Pad Mounted Transformer Do?

A pad mounted transformer is a type of electricity distribution transformer that is installed on a concrete pad at ground level to convert electrical power to voltages and currents that are safe and usable for homes, businesses, and utility companies. Being a key component of any electrical power distribution network, its significance cannot be overstated.

II. The Purpose of a Pad Mounted Transformer

A. Core Functions

At the heart of its functionality, a pad mounted transformer performs two main tasks:

  1. Step Down Voltage: It receives high-voltage electrical energy from a power line via an overhead or underground feeder circuit and “steps it down” to a lower voltage that is safe and usable for end users.
  2. Distribute Power: Once the voltage is stepped down, the transformer distributes this electrical power to residential, commercial, or industrial users.

III. Different Types of Pad Mounted Transformers

Pad mounted transformers come in various types, each tailored to specific needs and applications.


A. Single-Phase Pad Mounted Transformers


Single-phase pad mounted transformers are often utilized in residential areas where the electrical load is relatively low. They’re perfect for powering household appliances and small offices. Single-phase transformers by Daelim, such as our single-phase pad mounted distribution transformer, are designed to provide a safe and reliable power supply.


B. Three-Phase Pad Mounted Transformers


Three-phase pad mounted transformers are generally used in commercial and industrial applications, where the electrical load is high. They’re necessary for powering industrial equipment, large commercial buildings, and machinery. Daelim’s liquid-filled loop-feed pad-mounted transformer and liquid-filled radial-feed pad-mounted transformer are excellent examples of three-phase transformers designed for efficiency and durability.


C. Pad Mounted Transformers with Different Power Ratings


Depending on the application, you may require a pad mounted transformer with a specific power rating. Daelim offers transformers with various power ratings, including:
