Proyecto de la Segunda Revisión del Reglamento Técnico Ecuatoriano PRTE INEN 012 (2R) "TRANSFORMADORES DE POTENCIA" (Draft second revision (2R) of Ecuadorian Technical Regulation PRTE INEN No. 012 "Power Transformers") (11 pages, in Spanish)

The notified draft Ecuadorian Technical Regulation establishes the requirements to be met by power transformers immersed in PCB (polychlorinated biphenyl)-free insulating fluid and dry-type transformers, prior to the marketing of domestic and imported products, with the aim of protecting human safety and the environment and preventing deceptive practices.

The notified Technical Regulation applies to the following products:

·         Single-phase and three-phase power transformers, immersed in insulating fluid

·         Single-phase and three-phase power transformers, dry type

It does not apply to the following transformers:

·         Single-phase transformers with rated power less than 1 kVA and three-phase transformers less than 5 kVA

·         Transformers which have no windings with rated voltage higher than 1,000 V

·         Instrument transformers

·         Traction transformers mounted on rolling stock

·         Starting transformers

·         Testing transformers

·         Welding transformers

·         Explosion-proof and mining transformers

·         Transformers for deep water (submerged) applications
