Auto transformers, unlike power transformers, have an electrically connected primary and secondary circuit.
The primary and secondary circuits therefore have a number of winding turns in common resulting in smaller and lighter weight units than a power transformer for a given rating.
Auto transformers are frequently used in power applications to interconnect systems operating at different voltage classes, for example 132kV to 66kV for transmission.
Ampcontrol’s auto transformers are engineered to provide the most appropriate technical solution to a project including electrical and mechanical aspects of the design, along with ease of installation and maintenance, on-line monitoring and durable corrosion protection.
With a focus on providing maximum reliability, durability and efficiency for our customers Ampcontrol’s transformers are engineered and manufactured within our ISO9001 accredited Australian facility and stringently tested to AS standards in our fully equipped transformer test bay.
