What does a transformer do?

A transformer changes electrical voltage to a higher or lower level so power can be safely and efficiently used by different types of equipment.

Does a transformer waste a lot of power?

No. Well-designed transformers are highly efficient. Most of the power going in comes out on the other side, with only small losses.

Why are transformers important in power systems?

They allow electricity to be transmitted over long distances efficiently and then safely reduced to usable levels for homes, businesses, and industrial equipment.

Why does voltage sometimes drop when a transformer is under heavy load?

When more power is being drawn, current increases, which creates small internal losses and causes a slight drop in output voltage. This is normal and accounted for in design.

What is the difference between a primary and secondary winding?

The primary winding receives power from the source. The secondary winding delivers the transformed voltage to the load or equipment

What is voltage regulation?

Voltage regulation refers to how much the output voltage changes between no load and full load conditions. Lower regulation means more stable voltage.

What should I consider when selecting a transformer?

The main factors are required voltage, power rating (kVA), environment (indoor or outdoor), and the conditions where it will be installed.

What are transformer taps used for?

Taps allow small voltage adjustments to compensate for variations in the incoming supply, helping maintain consistent output voltage.

Besides transformers, what other equipment does TTW Energy manufacture?

TTW Energy also designs and manufactures substations, switchgear, and integrated power distribution systems to support complete electrical infrastructure projects.

Why choose TTW Energy over other manufacturers?

We offer flexible manufacturing for custom or standard designs, competitive pricing, shorter lead times than most competitors, and a broad product range under one roof.
