Overview Dimensions Documentation
Overview

The Concentrator is the communication bridge between the core sensing units and main station of InHand Wireless Overhead Line System. By adopting hybrid networking of short and long range wireless connection, the system supports channel monitoring and switching, fault alarming, system diagnosing and self-recovery, and breakpoint resuming of transmission. High reliability power supply system of solar energy and maintenance-free accumulator ensures stable operation of the system, allowing the utility operators to keep track of the operation and fault status of overhead lines. And, with big-data based comprehensive analysis of the status of distribution network overhead lines, including line faults, line losses, energy quality and etc., the InHand Wireless Overhead Line System can provide comprehensive and solid data support for the structural optimization of distribution networks. 


Features
Flexible Networking, Safe Data Transmission

The concentrators build short range wireless networks in-between, supporting star topology; and establish communication with the main station monitoring platform through 2.5G/3G/4G cellular network based utility VPN to upload data to main station, realizing monitoring of faults and operation status of the distribution network.  

           

Precision GPS Timing Based Precise Timescale

The Concentrator is embedded with GPS Timing module* and installed with high gain active antenna, precision of time service reaching 1us. By time service from the Concentrator through short-range wireless connection, the Overhead Line Sensors can acquire a high precision absolute timescale with precision of ±100us. (Note: Embedded *GPS Timing module of the Concentrator is an optional part.)  

                   

Synthesize Zero Sequence Current and Electric Field Signal

The concentrator acquires transient zero sequence current and electric field signal by three-phase synthesis to realize accurate on-site detection and locating of ground faults. It can also upload the waveform of the faulty moment recorded by Overhead Line Sensors to the main station for fault analyzing, retracing and sourcing.

                     

Reliable and Stable Communications

Reliable industrial-grade design, adopted industrial-grade cellular communication chip of major international manufacturer. Support channel monitoring, channel switching and fault alarming; system diagnosing and self-recovery; and transmission breakpoint resuming when communication recovers from interruption, to avoid loss of data.  


Ultra-low Power Consumption

Adopted low power consumption CPU and industrial-grade cellular module on the motherboard, and with special programming technology, the concentrator supports real-time two-way communication with the monitoring platform software and Overhead Line Sensors on ultra-low power consumption.  


High Reliability Power Supply System

The concentrator uses solar panel as main power supply, and a maintenance-free long service life chargeable accumulator as backup when the solar energy supply is unavailable. The backup accumulator can supply for continuous operation for 15 days of the Concentrator (depending on the selected capacity of backup battery).  The embedded high-performance processor will switch between solar panel and accumulator according to the result of real-time detection.


Remote Maintenance and Upgrade

Safe and convenient remote maintenance and upgrade, support batch and one-by-one auto maintenance or upgrade of multiple terminals. Support text message management.

      

Solid Shell, Dustproof, Waterproof, and Anti-rust

Solid anti-rust shell combined with sealing ring and waterproof joints, passes IP55 protection rating, ensuring long hours of safe and stable operation in outdoor environments.
