Hertzinno - Model HZ-OLF-100 - Smart Grid-Transmission Line Fault Indication System
The HZ-OLF-100 Smart Grid-Transmission Line Fault Indication System is designed to enhance the reliability and efficiency of power network operations by accurately identifying fault locations and types. Utilizing advanced passive acquisition technology, it effectively minimizes false alarms using current and voltage amplitude along with phase characteristics. Remarkably, the system requires no additional power supply, operating efficiently through solar energy, power induction, and lithium battery options. A standout feature is its ability to form a self-organizing network, allowing ultra-long-distance data transmission without reliance on 4G/5G networks, thereby reducing construction costs. The system boasts high adaptability to extreme outdoor conditions, functioning optimally in temperatures ranging from -25°C to 70°C. It continues to operate effectively even during prolonged periods of overcast and rainy weather. Further technical features include a combination of Gaussian Filtering and Wavelet signal processing for precise fault analysis and location, supported by synchronous fault phasor analysis.
0 False Alarm
- Fault location and fault judgment are realized by using current and voltage amplitude and phase characteristics.
The system adopts advanced passive acquisition technology to avoid the false alarm
No Need For Charging
- With 3 types power supply: Solar energy, Power induction and Lithium battery, for the system does not need additional power supply .
Easy to installation, easy to operation and maintenance.
No Need For Network
- By relying on a self-organizing network system, sensors and collection terminals can form their own networks, enabling ultra-long-distance transmission without the need for additional 4G/5G network signals, thus reducing construction costs.
High Environmental Adaptability
- Adaptable to outdoor environments with high temperature variations and humidity, capable of work in the temperature range from -25°C to 70°C.
Continuous one month of overcast and rainy weather does not affect its normal operation.
Core Technology
- Signal Filtering Method Combining Gaussian Filtering and Wavelet, intelligent analysis and localization of fault types based on global features.
Fault phasor analysis method based on synchronous supported and fault type discrimination based on state transition analysis.
