Transformers are components with a history and tradition dating back over 100 years since Hitachi was founded.
These transformers are installed at relay points in the transmission of electricity produced at power stations to consumers (such as households and factories).
These transformers play a vital role in leveraging the properties of electricity, in that less power is lost during transmission as the voltage is increased.
Electricity sent at high voltage is stepped down in stages at the relay point substation (transformer) and distributed at a voltage that is easier to handle.
These transformers respond to the increasing needs for long-distance electricity transmission at high currents from power sources in remote areas with the spread of power demand.
In addition to extra-high voltage (EHV) and high voltage (HV), they offer practical use of ultra-high voltage (UHV) transmission of up to 1000 kV.
Along with their high level of reliability, they make use of the latest technologies such as on-site assembly and gas insulation according to transmission grid issues and applications.
Phase compensating transformers improve the constantly changing power flow, reducing power loss and boosting system stability.
They offer functions to improve system stability and reliability and reduce power loss to improve power flow over the entire system.
