Recently, the project "Key Technologies for Efficient Ground Fault Handling in Arc Suppression Coil Grounding Systems to Prevent Cable Trench Fires", jointly developed by the Company and Shaanxi Electric Power Research Institute, was awarded the Second Prize for Scientific and Technological Progress by State Grid Corporation of China in 2023.
Notably, the pre-adjusted phase-controlled arc suppression coil complete equipment proposed and successfully developed by the Company features high compensation accuracy (residual current at fault point less than 2.5A) and rapid compensation current stabilization time (under 60ms). This innovative solution can more effectively suppress ground arc energy while significantly improving the sensitivity of single-phase ground protection devices.
