Tate Electricals manufactures wide range of power transformers upto 25 MVA with voltage class of 36 kV. These transformers are generally free breathing type. Oil filled in transformer is PCB free Mineral Oil / Midel 7131 / Silicon Oil / Nynas Nytro, etc. as per customer’s requirements. Wide range of transformers in accordance to above standards with different combinations can be manufactured. The transformers are generally designed and manufactured to comply with the IEC publications 60076.
The Power transformer is a one kind of transformer, that is used to transfer electrical energy in any part of the electrical or electronic circuit between the generator and the distribution primary circuits. These transformers are used in distribution systems to interface step up and step down voltages. The common type of power transformer is liquid immersed and the life span of these transformers is around 30 years. Power transformers can be classified into three types based on the ranges. They are small power transformers, medium power transformers and large power transformers.
- The range of small power transformers can be from 500-7500kVA
- The range of medium power transformers can be from -100MVA
- The range of large power transformers can be from 100MVA & beyond
Power transformers can be designed as either a single phase or a three phase configuration. There are numerous important specifications to identify when searching for power transformers. The specifications of power transformer include a maximum power rating, maximum secondary current rating, maximum voltage rating and o/p type. Power transformer specifications mainly include
- Phase is 3Ø
- Frequency if 60Hz,50Hz
- Primary Voltage is 22.9 kV
- Secondary Voltage is 6.6/3.3 kV
- Tap Voltage 23.9-R22.9-21.9-20.9-19.9kV
- Vector Dd0, Dyn11, etc.
