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:

- 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 (CRF) or outdoor use (CRFE).
