MV Cast resin voltage transformer (outdoor)

This outdoor dry-type current transformer is insulated with cast resin. It can achieve accuracy class of 0.2%-3.0% and/or 5P10-10P20. The Metropolitan Electricity Authority (MEA) of Thailand has been acquiring this range of TME current transformers for use in their metering system since 1998 to substitute imported products.

To date (2009), TME has supplied over 16,000 units of it’s cast resin voltage transformers.
