Optical Transformers

GK Power presents its Optical Current Transformer 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 our optical current transformer are:

• Broad bandwidth, capable of measuring both AC and DC currents up to the 100th harmonic and above.
• IEC 60044-8 Class 0.2 metering accuracy.
• Unlimited dynamic range.
• IEC 61850-9-2 LE compliant output with no merging unit required.
• Smaller size and lighter weight.
• Maintenance-free and longer life-span.
• Provides explosive failure mode prevention and open secondary protection.
• Solid insulation. No SF6 gas or oil is required. Environmentally-friendly.
