High-Precision Ground Fault Sensor

New Products / New Technology

The high-precision ground‑fault sensor is a core IoT‑based smart distribution‑network monitoring product developed by Shanghai Simliang Electronic Technology. The complete system comprises three key components: the Smart Grid Sensor (SGS), the Busbar Data Concentrator Unit (BDCU) with edge‑computing capabilities, and the Intelligent Analysis Application Software (IAAS). Leveraging an architecture that integrates terminal data acquisition, edge‑level aggregation, and cloud‑based analytics, it enables real-time monitoring of distribution‑line operating conditions, delivering functions such as equipment‑defect early warning, fault detection and location, power‑quality monitoring, real‑time power‑flow calculation, and dynamic line capacity augmentation. It is also well suited to accommodate large‑scale distributed renewable energy integration.

Distributed Fault Location System for Distribution Networks

New Products / New Technology

The distributed fault‑location system for distribution networks, developed by Shanghai Siliang Electronic Technology Co., Ltd., addresses key industry challenges: insufficient accuracy in zero-sequence current synthesis, which leads to frequent false alarms for ground faults, and the high failure rate of conventional pole‑mounted aggregation units. The system is suitable for distribution lines operating at 35 kV and below. It employs the principle of fault‑traveling wave propagation to achieve precise fault location: when a fault occurs on a distribution line, traveling waves are generated and propagate toward both ends. By monitoring and acquiring fault signals and analyzing the time difference between the arrival of these traveling waves at the device, the system can accurately pinpoint the fault location.

AI-Powered Panoramic Dynamic Capacity Enhancement System for Transmission Lines

New Products / New Technology

The AI‑powered panoramic dynamic capacity‑augmentation system for transmission lines, developed by Shanghai Siliang Electronic Technology Co., Ltd., aligns with the policy direction of building a new‑type power system supported by digital and intelligent grids. By integrating advanced technologies such as inductive power harvesting and self‑powering, artificial intelligence, the Internet of Things, multi‑sensor data fusion, and AI‑based visual analytics, it effectively resolves the power‑supply bottleneck of smart, digitized equipment on transmission lines. The system enables intelligent monitoring and early warning for transmission lines while, under the premise of ensuring insulation safety, efficiently unlocking previously underutilized transmission capacity, thereby contributing to the development of a resource‑efficient, digital grid.
