Damping reactors are designed to be installed in series with a shunt connected capacitor bank. Their function is to limit inrush currents occurring during switching, to limit outrush currents due to close-in faults, and to control the resonant frequency of the system due to the addition of capacitor banks.
During normal operation, the capacitor rated current flows through the damping reactor. The maximum permissible (overload) current of the damping reactor is equal to the corresponding value of the capacitor bank, which, according to IEC Publication 70 is 1.3 times the current obtained with rated sinusoidal voltage across the capacitor.
With regard to installation, these devices may be identified as:
Single phase or three phase
Cast resin dry type, conventional dry type or oil immersed
With or without magnetic shield
For indoor or outdoor installation
With or without enclosure
With fixed or variable reactance

TMC has been a leading enterprise in the field of transformer design and manufacture since 1937.
A wholly owned Australian company with its head office in Victoria, TMC excels at providing high quality induction equipment to the electrical power industry, with an emphasis on meeting exacting specifications and standards, while minimising cost.
TMC is fully accredited to the international quality standard ISO9001, and continues to build on a tradition of product excellence and customer focus.
Research and Development
The TMC Research and Development department developed TMC’s own cast resin transformer technology which has gained wide acceptance in the mining and building construction industries.
TMC’s cast resin transformers are exported to the Middle East and Asian markets and TMC casting technology is licensed to companies in Asia.
The TMC Research and Development department routinely studies cast resin electro-mechanical phenomena providing TMC with the best possible understanding of all aspects of cast resin transformer technology
TMC now offers a comprehensive range of technology products and services.
