CT RINGS
Current Transformers
To feed the earth unit of our protection relays, a large choice of CT rings is available, either open and closed type.
Moulded case current transformers for the measurement of AC currents up to 3000A, with inner diameters from 15 to 80 mm.
They are made of a non-flammable material and have heavy insulation.
They are equipped as standard with EA type mounting brackets.
Moulded case current transformers for the measurement of AC currents up to 3000A, with inner diameters from 15 to 80 mm.
They are made of a non-flammable material and have heavy insulation.
They are equipped as standard with EA type mounting brackets.
Current transformers moulded in selfextinguishing resin for the measurement of AC currents from 50 to 60000A.
With inner diameters between 106 and 500 mm, these transformers are often used on bushings of power transformers or on generator bushing insulators.
Two versions, indoor or outdoor, are available. The outdoor version is equipped with a weatherproof terminal box fitted with 2 cable glands.
Customized solutions are also available, please contact us.
