Tesla Transformers Ltd.

Govind Pura, Bhopal, Madhya Pradesh

Dry type Transformers, class 'H' insulated, have insulating materials which are with high dielectric strength and are capable to withstand high temperatures. The temperatures are generally made to comply with IEC-60076/IS-2026/IS-1171. Range upto 1600 KVA and 11 KV Class.   Available versions :   Open type execution for installation in an existing panel or enclosure. Well ventilated enclosure with lip-cut louvers & baffles for outdoor installation. Non ventilated enclosure for outdoor installation. Advantages :   Use of non-biodegradable materials makes these suitable for strict environmental   conditions. No fire or explosion hazards because of use of nonflammable materials & absence of any liquid insulation. Non-requirement of oil sump makes these ideally suitable for installation near   load centers thus reducing cabling costs and improving voltage regulation.

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.   Features Rating upto 3 MVA HV Voltage 11, 22 & 33 or as per customer requirement.
