Transformer

The ABB AbilityTM Power Transformer, unveiled at the 2018 Hanover Fair, in Germany, will be the world’s first integrated solution for digitally enabled power transformers, fundamentally changing the transformer paradigm. All power transformers leaving ABB factories will soon come enabled with digital capabilities, enabling remote monitoring and data analytics of its vital parameters in real time. This will enhance reliability and enable higher utilization of grid assets and power networks.

ABB has successfully tested a cost-effective way to replace petroleum-based mineral oil insulating medium with environmentally friendly natural ester fluid in the world's largest sealed 200 megavolt ampere (MVA), 420 kilovolt (kV) single-phase transformer. This significant technology breakthrough pushes the development of environmentally friendly high-voltage (HV) power transformers to a new level.

ABB Low Voltage Dry Type transformers are built to last and are designed with exclusive features. With easy installation and all of the specifications you trust, it’s easy to see why ABB QL dry type transformers are preferred by contractors. Our Type QL transformers meet DOE 2016 efficiency standards. They are available with aluminum or copper windings and in all three temperature rise ratings.

DOE 2016 Efficiency Three Phase (EX)
Square D leveraged 100 years of transformer design and manufacturing with the latest technology in core, coil, and enclosure, to launch the new EX offering.

ABB offers a wide range of current transformers for alternating current and Shunts for direct current.

If current in a circuit is too high to be applied directly to a measuring instrument, a current transformer is used to reduce the current accurately proportional to the current in the circuit, which can be conveniently connected to measuring and recording instruments.
