Frequently Asked Questions
What is the difference between a substation and distribution transformer?
Substation transformers are larger (typically 10+ MVA) and handle higher voltages (69kV+) for bulk power transmission. Distribution transformers are smaller and step voltage down for end-user delivery.
What is an auto-transformer?
An auto-transformer uses a single winding with a tap point, sharing part of the winding between primary and secondary. They are more compact and efficient for smaller voltage ratios but provide less isolation than two-winding designs.
Can you provide engineering and installation services?
