Transmission Line Testing
Correct line parameters are crucial for reliable and selective operation of your distance protection device. It also allows an accurate fault location after an event on the line by evaluating the fault recorder. The set of parameters contains the positive sequence impedance, the zero sequence impedance and the k-factor. For double or multi-circuit lines the mutual coupling impedance is required in addition.
These parameters are often derived from network calculations, which do not represent the actual values due to unknown soil properties, such as different soil resistivities, water pipes or other buried conductors. This leads to a malfunction of your distance protection relay by under- and overreach. This results in outage and loss of grid stability.
With our test solutions, you can determine required line parameters in a quick and safe way.
Transmission Line Monitoring
Electric transmission line condition monitoring solution
The transmission line grow rapidly. So it need more time of line patrol maintenance work of the operators, and master the surrounding environment condition information real-time.
LoRa extreme distance and low power consumption characteristics, solve the data long distance transmission in a complex environment problem, through all kinds of detector and acquisition equipment, etc. installed in the transmission line, digital acquisition of all kinds of information of power line, ensure real time control of the running state of the transmission line to ensure the safe operation of power grid.
Distribution Overhead Line Monitoring & Analytics
Fault Detection, AI-enabled Preventive Grid Analytics
Consisting of overhead line sensor, concentrator and analytics platform, the SNAGS Wireless Overhead-lines System (WOS) collaboration with IWOS helps utilities detect & locate faults, reduce power outage, and move from reactive to preventive maintenance. The WOS is field proven by more than 120,000 line sensors installations by 2019. Leveraging big data analytics and artificial intelligence, the WOS has accumulated more than 28 million waveform data of line events and successfully detected more than 35,000 faults including ground faults, short circuit faults, inrush current, lightning, and more.
