ABB SAFT103 is a high-precision fiber optic current transformer (FOCT) designed for medium and high-voltage power systems. Engineered to deliver reliable current measurement and protection, SAFT103 utilizes optical fiber technology to eliminate issues like magnetic saturation and insulation degradation found in traditional electromagnetic current transformers (CTs). This makes it ideal for smart grids, digital substations, and renewable energy applications where accuracy, reliability, and immunity to electromagnetic interference (EMI) are critical. ABB SAFT103 supports seamless integration with IEC 61850-based substation automation systems, providing digital current signals for protection, metering, and control. Its compact design and long lifespan make it a cost-effective solution for modern power infrastructure.

4. Application Areas and Application Cases
Industry Applications:
Power Generation/Distribution: Digital substations, renewable energy (solar/wind) grid integration.
Industrial Manufacturing: High-voltage motor control, arc furnace protection.
Transportation: Railway electrification, electric vehicle (EV) charging infrastructure.
Case Study: A major utility company deployed ABB SAFT103 in a 220 kV smart substation to replace outdated electromagnetic CTs. The FOCT’s digital output (IEC 61850 protocol) enabled real-time fault detection and reduced relay response time to <10 ms, improving grid stability and cutting annual maintenance costs by $50,000.
5. Competitive Comparison
Compared to traditional electromagnetic CTs, ABB SAFT103 eliminates 铁芯 (iron core) saturation and oil-based insulation risks, offering a 30-year lifespan without degradation. Unlike some competitors’ FOCT models, it provides built-in waveform recording and GOOSE trip signal support, simplifying system integration. Its wide temperature range and seismic resistance also make it preferable for extreme environmental applications.

6. Selection Recommendations
Current Range: Choose a rated current 20% higher than the maximum load to accommodate inrush currents (e.g., motor starting).
Communication Protocol: Prioritize IEC 61850 compatibility for digital substations; use FT3 converters for legacy systems.
Environment: Opt for IP67-rated models for outdoor/harsh environments; IP54 for indoor setups.
Scalability: Ensure the FOCT supports parallel operation if future current upgrades are planned.
7. Precautions
Installation: Avoid bending fiber optic cables beyond a 30 mm radius; use armored cabling for outdoor installations.
Grounding: Properly ground the FOCT’s metallic housing to prevent electrostatic discharge (ESD).
Maintenance: Regularly clean fiber connectors with alcohol swabs to maintain light transmission efficiency.
Firmware Updates: Use ABB’s dedicated software to update firmware and validate self-diagnostic reports quarterly.
