The ARTECHE Optical Current Transformer is presented as an alternative to the existing conventional current transformers, providing an advanced measurement solution for both metering and protection applications, based on a cutting-edge patented optical sensing technology. Some of the main features of the optical current transformer are:
Broad bandwidth, measuring both AC and DC currents up to the 100th harmonic and above.
IEC 60044-8 Class 0.2 accuracy for metering.
Unlimited dynamic range.
IEC 61850-9-2 LE compliant output with no merging unit required.
Smaller size and lighter weight.
No maintenance required and a longer life-span.
Prevents from explosive failure modes or open secondary situations.
Solid insulation. No SF6 gas or oil is required. Environmental friendly.
