Optical Current Transformer SDO-OCT
ARTECHE’s SDO-OCT is a passive, modular optical current transformer that can be used for any voltage level. The device is based on three elements: an optical current transducer (SDO-ICT), the insulator and the merging unit (SDO MU).
SDO-ICT is a fully passive optical transducer that provides a digital measurement solution for metering and protection applications. The passive interferometric transducer can offer Cl 0.2 accuracy over an unlimited range of primary currents.
The SDO-ICT transducer can be mounted with different types of post-insulator that cover any insulation level that might be required. The post-type insulator uses solid insulation. There is no risk of violent failure modes and it is environmentally friendly.
Maintenance: There is no risk of insulator leakage (no oil or gas is used) and no maintenance is required.
The SDO-ICT can also be used for DC measurement.
