Wind energy (or wind power) is the process by which wind is used to generate electricity.  Wind turbines convert the energy in wind to electricity by rotating the propeller, like blades around a rotor. The rotor turns the drive shaft, which turns an electric generator.

Transformers play a key role in the power transformation of Wind Energy.

They serve as Generator Step Up (GSU) to step up the voltages at different stages. All wind generators need a pad mount transformer at its base or Nacelle for the first stage step up and then collectively thru rings feeds a collector main power transformer that finally boosts the voltage to connect with the transmission grid. VTC and GTC make both the liquid filled pad mount and power transformers that are powering several wind farms effectively. The pad mounts are custom designed and built to suit the unique dynamic and harmonic loads of the wind energy characteristics and assure against gassing. In fact VTC assures a 3 year warranty against gassing on all its Pad Mount designs.

Power collector transformers right up to 400 MVA / 345 kV serve the sub stations at many wind farms.

When you think of Renewable Energy, think of Reliable Transformers – Think VTC & GTC.


The energy the Earth receives from the sun, primarily as visible light and other forms of electromagnetic radiation is a powerful source of energy. The technologies that are utilized in this segment are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties and designing spaces that naturally circulate air.

A photovoltaic power station, also known as a solar park is a large-scale photovoltaic system (PV system) designed for the supply of merchant power into the electricity grid. They are differentiated from most building-mounted and other decentralized solar power applications because they supply power at the utility level, rather than to a local user or users.

Utility scale solar field thru solar panel arrays harness the solar energy and thru Photovoltaic cells and invertor, generate electricity that needs to be boosted in voltage levels to make them useful for transmission. This is where VTC and GTC design and manufacture to the onerous harmonic loads of the solar energy segment. VTC’s pad mount transformers serve as inverter step up (ISU) to step up the voltages from solar panel arrays that finally feed a collector power transformer at the substation. Here again, VTC and GTC design and supply large power transformers that boost the voltage levels to synchronize with the Grid Voltages.
