The Benefits of Panel Transformers for High Voltages

Why panel transformers are suitable for high energy applications


In a nutshell, transformers change from one voltage mode or another. They may be used to step-up or step-down. They could also be used to change from AC to DC electrical systems. For high voltage applications, this is where panel transformers come to the fore. We at Total Control and Distribution offer panel transformers for single phase and three phase AC systems.

Transformers can be encased in this four gang splitter, seen at the top of this post. In this guise they are designed for external use; for example, to permit the use of heavy machinery. Panel transformers are designed to be placed in external cabinets. They are mounted onto the cabinet, out of harm’s way for electricians. Or for use in a substation.

Before reaching your home or office, electrical power is gradually stepped down from the National Grid system. The average electricity pylon carries up to 400 kV before stepping down to 275 kV, 132 kV, and 33 kV power lines. From there, transformers are used to make the step from high voltage to low voltage, by means of more localised substations. These either have a capacity of 11 kV or 6.6 kV depending on the locality. In the substation, panel transformers are used to step down the supply to a maximum of 240 V (single phase) or 415 V (three phase).

It is clear we shall be lost without them. For a start you wouldn’t be able to see this post. You wouldn’t be able to plug in your outdoor power tools. Hospitals wouldn’t be able to cope unless they have their own generators.

We at TCAD sell panel transformers that cover the following values:

  • 240 V (single phase) to 110 V and 24 V;
  • 415 V (three phase) to 240 V, 110 V, and 24 V.
