Electrical Network Management instrument transformers

This CT range is in cast resin, with excellent withstand to severe environment in terms of temperature, vibrations, salt, moisture and contaminants.

Secondary terminal connections are flying leads, to avoid any potential risk of loosening connections, or vibration resonance that may break terminals. TR33xy and TR66xy are designed to adapt to various busbar sizes, and accommodate large cores and windings to match demanding requirements in protection and accuracy classes. Fixing is performed tightening 2 horse shoe-shape clips on amagnetic support plate, enabling very strong hold on busbar.

Moulded case current transformer for the measurement of AC currents up to 150 A.

This current transformer has been designed to meet the most demanding requirements, especially for protection relays.

Spacers can be inserted. Then rivets are replaced with screws.

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.

Current transformers moulded in self-extinguishing resin for the measurement of AC currents from 150 to 15 000A.

This range has high performance characteristics, and demonstrates an excellent resistance to shocks, vibrations, salt and moisture.

It is approved by the french Navy.

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.

The change to newer, faster and more selective protective system makes it necessary to replace existing current transformers with different output, class, ratio, number of secondaries to suit the needs of the new protection.

The best solution is to use split-core current transformers on insulated cables or outside single phase metalclad units. This solution is very economical because:

- It is not necessary to dismantle and remake the cable sealing ends on the metalclad units.

- There is no need to recommission and test the main equipment.

- It reduces the risk of damage and the length of outages at reduced costs.

These current transformers are avalaible for indoor use (CR) or outdoor use (CRE).

Current transformers vacuum moulded in self extinguishing epoxy resin for the measurement of AC up to 800A.

This range is particularly suitable when primary connection using bars is required.

Current transformers for the measurement of AC currents from 40 to 8 000A.

This low cost range couples a low voltage current transformer and an insulating epoxy tube.

Current transformers vacuum moulded in self extinguishing epoxy resin for the measure of AC currents from 0 up to 2500A - 36kV.

This comprehensive and compact range of current transformers has been designed to meet the requirements of MV switchgear manufacturers. It allows double ratios up to 600-1200 A, and offers up to 4 independent cores.

Double pole voltage transformer vacuum moulded in self extinguishing epoxy resin for the measure of AC voltages between phases up to 36 000 V, with rated outputs up to 100 VA cl0,2 or 150 VA cl0,5.

This range is also suitable for the power supply of auxiliaries up to 2 500VA clA.

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 measure of AC currents from 50 up to 5000A.

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

Current transformers moulded in self extinguishing resin for the measure of AC currents from 50 up to 5000A.

With inner diameters from 200 to 400 mm, these transformers are often used on power transformers bushings or on generator bus bars. Two versions, indoor or outdoor, are available. The outdoor version is equipped with a weatherproof terminal box fitted with two 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.

The change to newer, faster and more selective protective system makes it necessary to replace existing current transformers with different output, class, ratio, number of secondaries to suit the needs of the new protection.

The best solution is to use split-core current transformers on insulated cables or outside single phase metalclad units. This solution is very economical because:

- There is no need to recommission and test the main equipment.

- It reduces the risk of damage and the length of outages at reduced costs.

These current transformers are avalaible for indoor use (CRF) or outdoor use (CRFE).

Current transformers vacuum moulded in self extinguishing epoxy resin for the measurement of AC currents from 50 to 12 000A.

This range is particularly suitable for the measurement of high currents.

Current transformers vacuum moulded in self extinguising epoxy resin for the measurement of AC currents up to 3000A.

This comprehensive and compact range of current transformers has been designed to meet the requirements of MV switchgear manufacturers. It offers a very low level of partial discharges. It allows double-ratio up to 600-1200A by primary coupling, as well as up to 5 independant secondary windings.

Current transformers vacuum moulded in self extinguishing epoxy resin for the measure of AC currents from 0 up to 2500A - 24kV.

This comprehensive and compact range of current transformers has been designed to meet the requirements of MV switchgear manufacturers. It allows double ratios up to 600-1200A, and offers up to 4 independent cores.
