Information Application transformer cooling Fans for transformer cooling 06/2017 Application transformer cooling General information As globally important connection points to ensure a reliable electricity supply, power transformers play a key role in society and its infrastructure. This kind of system can be found in electricity plants, substations, solar and wind-driven power stations and in many other areas of energy generation and distribution. During operation, heat losses occur. These are concentrated in what are known as hot spots and significantly inhibit the service life of the transformer....

Information Application transformer cooling Dry transformers In this design, the high-voltage winding is cast in resin, while other solid insulating materials are used in the low-voltage winding. Insulation of the coils from one another and from the core is guaranteed by sufficiently large air gaps. A vertical air flow along the surfaces of the coils and in cooling ducts in the coils ensures dissipation of the heat losses.
