Today’s Overhead Line Fault Detection Needs–With Tomorrow’s Smart Grid Capabilities
Intelligent Overhead Line Sensing up to 138kV
- Smart adaptive sensing of events, load, voltage and temperatures
- Intelligent algorithms to provide highly accurate, configuration-free overhead line fault detection
- Provision of data that allows you to calculate distance to fault to within 200 ft.
- True voltage measurement enables detection of load imbalance and provides data for volt/VAR reduction
- Dynamic rating of lines using ambient and conductor temperature readings
- Tested in accordance with the IEEE 495-2007 standard for faulted circuit indicators
There is no more flexible overhead line fault indicator and monitoring solution than LineIQ. No other provides advanced fault detection out of the box, and allows you to upgrade to more intelligent monitoring capabilities via simple firmware download.
For utilities, quickly detecting faults, correcting them, and restoring power to customers is paramount. Most fault current indicators show a flag or light upon detecting a fault. Some provide fault phase and magnitude with a waveform and communications back to SCADA.
From T&D World Magazine: Baltimore Gas & Electric optimizes placement of fault circuit indicators utilizing monitoring devices from GridSense and one other provider. (pdf).
LineIQ does more than just fault detection
LineIQ monitors overhead network lines up to 138kV, letting you quickly determine fault location and cause, and quickly restore power even as you prevent future outages.
At the system’s heart is an innovative, self-powered sensor easily installed on energized lines. The sensor enables continuous capture of critical performance data, including:
- True voltage measurement+
- Fault direction
- Fault waveform
- Load profile
- Power factor
- Line status and condition
- Ambient and conductor temperature
- Time-stamped event recordings
Retrieve data locally or remotely
On your laptop, retrieve data onsite via wireless connection with the GridSense LocalLink (range up to 150ft [50m]).
The GridSense Communications Gateway supports both solicited and unsolicited reporting, and allows wireless, remote data retrieval via cellular, Ethernet, mesh radio, Wi-Fi and more. Supported messaging protocols include DNP3 and IEC 61850*.
