ABB Transformers - Styles and Types
ABB offers a full range of transformer products and solutions for ANSI, IEC and other local standards. ABB is a major transformer
manufacturer throughout the world and offers both liquid-filled and dry-type transformers.
ABB Transformers are passive electrical devices. This means that a combination of static components could multiply a signal by values less than one, they can move the stage of a signal, they can weaken a signal due to the fact that it is not composed of the appropriate frequencies, they could manage complex circuits, however, they could not increase by even more than one because they lack gain. ABB Transformers are designed to transform or "step down" a higher major circuit voltage to a lesser voltage which is then used to operate the command or switching components of the main circuit. ABB has a complete line of Control and Isolation Transformers.
Zurich based ABB specializes in control transformers and other areas of electrification innovation. ABB is a worldwide leader in industrial electronics technology applications of factories, plants and other large operations. ABB technology is reliable and award winning as it is in demand and it has been tried and tested.

ABB Isolation Transformers
ABB Isolation Transformers also known as insulating transformers describes how the transformer is constructed. ABB Isolation
Transformers have separated primary and secondary windings. A common type of Isolation Transformer is the Control Transformer.
Control Transformers often provide stability and regulation. More information on Control Transformers below:
ABB Control Transformers
ABB Control Transformers are designed to provide secondary voltage stability or regulation to a large extent. These ABB
Transformers are also known as Industrial Control Transformers, Machine Tool Transformers, or Control Power Transformers (CPTs).
One of the many benefits of using a control transformer is the inherent security of the voltage supplied from the transformer, as it can manage extreme peaks in demand. When the start button on a motor starter is pushed and the contactor coil energizes, there is an extremely short (normally 30 to 50 nanoseconds) surge in "inrush current". This peak can surpass 10 times the normal existing circulation, and transformers deal with these peaks with more success in comparison to traditional transformer supply.
Using a control transformer to provide power allows a safer and more efficient control circuit voltage to be used in higher functioning voltage applications. The superb inrush current, dealing with characteristics of transformer-provided-power, likewise, creates a more effective power supply.
As an example, in a starter panel designed to start a 500V electric motor, the contactors and relays used to switch the electric motor on or off would typically use electromagnetic coils rated for a reduced voltage.
To provide this current without the demand for a different power supply, power is secured off the inbound 500 volt feed, which then travels through a control transformer. This set-up would certainly provide the reduced control circuit voltage.
Dry-Type and Liquid-filled Transformers
ABB offers a complete line of Dry-Type and Liquid-filled Transformers for applications across the board.
ABB Dry-Type Transformers meet strict parameters with respect to electrical system demands and functioning in areas with extreme climatic conditions. ABB's dry and cast transformers are very low maintenance and are manufactured in accordance with industry and international standards including ISO 9001.
ABB's liquid-filled transformers offer a complete range of power and distribution designed to grant the reliability, durability, and efficiency required in utility, industrial, and commercial applications. ABB's liquid filled transformers are manufactured in accordance with the most demanding industry and international standards. Transformers can be used for indoor or outdoor applications and can be provided with off-load and on-load tap changers.
Transformer Applications
ABB Transformers are generally used in commercial starter circuits where the primary circuit voltage is not appropriate for
use in the control circuit and where a separate control circuit feed would not be sensible.
ABB Transformers range in size and function. A broad assortment of transformer styles are used in electronic and electric power applications. Transformers are essential for the transmission, circulation, and utilization of electrical energy.
