A Three Phase Totally Enclosed Non-Ventilated (TENV) transformer is a specific type of electrical transformer designed for three-phase power systems. It shares many characteristics with single-phase TENV transformers but is optimized for three-phase applications, which are commonly used in industrial and commercial settings.

Here are the key features of a Three Phase TENV Transformer:

  1. Enclosure: Like other TENV transformers, the enclosure of a Three Phase TENV transformer is fully enclosed and sealed, preventing the ingress of contaminants like dust, dirt, and moisture. This level of protection is essential in environments where cleanliness and environmental protection are crucial.
  2. Cooling: These transformers use natural convection or radiation for cooling, just like their single-phase counterparts. Heat generated during operation is dissipated through the enclosure walls, and there are no external fans or ventilation openings.
  3. Three-Phase Power: A Three Phase TENV transformer is designed to handle three-phase power, which involves three alternating currents that are out of phase with each other. Three-phase power is commonly used in industrial and commercial applications due to its efficiency and ability to power heavy machinery and equipment.
  4. Applications: Three Phase TENV transformers are commonly used in industrial settings where protection against environmental factors and efficient power distribution are important. They might be found in factories, manufacturing plants, data centers, and other large-scale facilities.
  5. Efficiency: Similar to single-phase TENV transformers, Three Phase TENV transformers offer protection against contaminants but might have slightly lower efficiency compared to transformers with active cooling mechanisms.
