For the safety of nuclear power plants, the new generation of substation equipment in nuclear power plants needs to monitor milliamperes - level small currents in real-time. Due to strong magnetic field interference, limited installation space, and issues with salt and alkali corrosion in the field environment, SIO has specifically developed core components, improved the sensor winding process, and designed a special skeleton structure. The device has passed multiple dynamic simulation tests and is widely supplied to several nuclear power plants across the country.

Applying cathodic protection current to pipelines provides corrosion protection. However, stray currents from grounding systems near railways or substations may interfere with the cathodic protection current, leading to over-protection or under-protection of certain parts of the pipeline, which can result in corrosion issues. By measuring the cathodic protection current, stray current interference can be detected and addressed in a timely manner, ensuring the safety of the pipeline.

In the field of current sensors, optical fiber current sensors, due to their high precision, strong electromagnetic interference resistance, and excellent insulation performance, can meet the demands of various conventional and extreme environments, demonstrating exceptional adaptability to working conditions. They are widely used in scenarios including power supply current monitoring, electrical switch testing, and experimental centers at universities and research institutes. Additionally, thanks to their compact size and portability, optical fiber current sensors can replace traditional current transformers, simplify later calibration and calibration processes, and enable traceability with tracking reports.

Current calibration of magnetic particle testing machines is essential for ensuring equipment safety, improving detection efficiency, and playing a key role in maintaining equipment performance. SIO Hand-held Fiber Optic Current Meter not only accurately captures current waveforms and reflects magnetization time for current calibration, but also, due to its compact size and portability, allows for on-the-go measurements. It is highly recognized by industry clients.

Traditional current sensors such as current transformers, Hall sensors, and Rogowski coils may experience drift errors and decreased accuracy during long-term daily use. Optical fiber current sensors, with their high precision and interference resistance, can replace standard sources for on-site calibration services. Currently, SIO has established partnerships with multiple calibration and testing organizations, and its products are widely used in the industry. Additionally, the on-site calibration services provided by our company can meet the on-site calibration needs across various industries.
