Solar Transformers

Transformers are critical components in solar energy production and distribution. Historically, transformers have “stepped-up” or “stepped-down” energy from non-renewable sources. There are different types of solar transformers including distribution, substation, pad mounted and grounding. All solar transformers have specialized needs that impact costs. Normally these type of transformers are accommodated by devices that measure heat related volume variations. Gas cushion is used to compensate the volume variation due to heat. Normally the gas is nitrogen. This gas is thermally uncoupled from the dielectric liquid.

Solar Applications

Tesla understands the needs of the solar developers and has successfully designed and shipped transformers for power distribution applications in a solar farm using PV modules in India and throughout Asia-Africa continental. We have been successfully meeting the stringent specifications of customers and have a design which precisely fits these applications. The transformers are specially designed with low losses but high efficiency standards to meet the industry's stringent demands.
