With more than 35 years of experience and more than 100.000 units installed, Tesar has given its contribution to distribute electrical energy all over the world. From the hottest Middle-East Regions to the coldest Siberian town, Tesar distribution transformers are proven suitable for any kind of environment and climate. Tesar standard production line for distribution Transformers ranges from 100 kVA to 3.150 kVA with rated voltage up to 52 kV.
Power transformers with rated power up to 20 MVA complete the offer of transformers dedicated to energy distribution. Mostly required with MV/MV rated voltage, power transformers are meant for applications such as interconnection between distribution grids or to realize an internal distribution grid in big power plants.
A number of industrial and civil applications require specific transformers designed to supply non-linear loads which may introduce a significant harmonic content. Tesar is specialized in design and manufacturing of converter transformers suitable for various applications which may involve equipment such as variable speed drives, frequency converters or generator excitation systems. Rectifier transformers are manufactured with single and multiple secondary windings for 6-pulse, 12-pulse, 18-pulse and 24-pulse rectifier systems.
After the Kyoto protocol, EU focused on an ambitious goal: the so called climate energy package 20-20-20, which aims to reduce the greenhouse gas emission by 20%, to rise up 20% the energy produced by renewable sources and to finally reach the target 20% to get energy saving: all within 2020.
Tesar manufactures special transformer for Hydro Power Plant, Photovoltaic Plants and Wind Farms, supporting the always increasing necessity of a sustainable energy generation.
Since the very beginning of its history, Tesar started developing transformers dedicated for railway & subways electrification. DC motor actuated trains are supplied through a rectification system composed by transformer and rectifier. On the base of the specific system, Tesar is capable to supply 6-pulse , 12-pulse , 18-pulse and 24-pulse rectifier transformers, in double-storey or interleaved configuration, suitable for the specific duty cycle required according with IEC 60146 and EN 50329 standard.
