Electrical Traction - Railways instrument transformers

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-flamable material and have heavy insulation. They are equipped as standard with EA type mounting brackets.

Current transformers moulded in self extinguishing resin for the measurement of AC current from 200 to 8000A.

This range has an excellent resistance to shocks, vibrations, salt and moisture.

Current transformers moulded in self extinguishing resin for the measurement of AC currents from 50 to 60 000A.

With inner diameters between 106 and 500 mm, these transformers are often used on bushings of power transformers or on generator bushing insulators. 

2 versions, indoor or outdoor, are available. The outdoor version is equipped with a weatherproof terminal box fitted with 2 cable glands.

These ring type current transformers are available for indoor (ORX) or outdoor use (OREX). They have been designed to meet the requirements for measuring:
- line currents
- zero-sequence currents in the neutral of power transformers
- earth fault currents in power transformers.

The secondary terminals are accessible, either directly in the case of indoor equipment (ORX), or through a watertight terminal box in the case of outdoor application (OREX). Several types of terminal boxes are available depending on the required characteristics.

In addition to excellent mecanichal strength, these insulators have a high resistance to corrosive atmospheres and fire. They can be installed in any position.

Moulded case current transformers for the measurement of AC currents up to 3000A, with inner diameters from 25mm up to 60mm.

They are made of a non-flamable plastic material and have heavy insulation. They are equipped as standard with EA mounting brackets.

This range has been designed to meet the demanding requirements of protection relays.

Moulded case current transformers for the measurement of AC currents from 100A to 8000A.

They are made of a non-flamable plastic material and have heavy insulation. This comprehensive and compact range fits most busbars, from 30 to 160mm.

Split-core current transformers moulded in self-extinguishing resin.

This range has been designed to offer an excellent accuracy whatever the location of the primary conductor within the transformer window.

Outdoor current transformers for the measurement of AC currents up to 4000A.

They are moulded in selfextinguishing resin and have heavy insulation as standard. They are equipped with a weatherproof terminal box fitted with 2 cable glands.

This range complies with the European standards EN 50014 and 50019 «enhanced safety».
