Current transformers moulded in self-extinguishing resin for the measurement of AC current from 50 to 60000A.
With inner diameters between 40 and 500 mm, these transformers are often used on bushing of power transformers. Or on generator bushing insulators. 2 versions, indoor or outdoor, are available. The outdoor version is equipped with weatherproof terminal box fitted with 2 cable glands.
