MV Cast resin voltage transformer (indoor)

This indoor dry-type voltage (potential) transformer is insulated with cast resin. It can achieve accuracy class of 0.2% - 0.3% and/or 3P or 6P. Typically or installation inside electrical cabinets or indoor areas with limited space. Can be substituted with imported products.

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