LV Cast resin window / ring type current transformer (single phase) (indoor/outdoor)

This low voltage (LV) window/ring dry-type current transformer is insulated with cast resin. It can achieve accuracy class of 0.6. It is typically installed inside metering cabinets or indoor/outdoor areas with limited space. The Metropolitan Electricity Authority (MEA) of Thailand has been acquiring this range of TME current transformers for use in their metering system since 2003 to substitute imported products.

To date (2024), TME has supplied over 49,600 units.
