Handheld Guidance for Precise Fault Location
The INSIGHT M701 is a purpose-built handheld device that enhances fault location in challenging network conditions, particularly in compensated and isolated systems. While AIQ’s L700 and M700 systems provide highly accurate distance-to-fault values, interpreting these in real-world scenarios can be difficult when fault signatures are distorted or ambiguous. The M701 complements these systems by offering real-time directional guidance in the field.
Designed for use between two monitored nodes, the device allows operators to physically stand beneath the overhead line, select a reference point, and receive immediate feedback indicating whether the fault lies upstream or downstream. This guided step-by-step process is repeated until the fault is precisely located, reducing diagnostic time and improving restoration response. The M701 is an essential tool for network operators who need clarity, speed, and confidence in the field.
Key Features
Developed as a field companion to AIQ’s monitoring systems, the M701 simplifies the final step in fault tracing. Operators can use the device to test between two known nodes, standing directly beneath the line to determine whether the fault lies upstream or downstream. Repeating the process quickly narrows down the exact fault location, reducing response time and improving restoration efficiency.
Built for the Field
The M701 is lightweight, user-friendly, and purpose-built to guide line crews in narrowing down fault locations during live investigations.
Complex Network Support
Particularly useful in compensated and isolated networks, the M701 complements algorithmic analysis with practical, on-the-ground guidance.
Frequently Asked Questions
The L700 System can detect Phase to Phase Short Circuits, Earth Faults including those of High Resistance (up to 10 kΩ) Sensitive Earth Faults, Cross Country Faults, Open Circuits; permanent, transient and Incipient faults
The L700 and M700 Systems achieve time synchronisation through the use of the GPS timing reference, which enables data synchronicity of 1 micro-second.
Yes, the system has been designed to integrate with SCADA, DMS and ADMS.
Notification of faults and disturbances are communicated to the field team’s smart phones via email and SMS as required and are observable in detail on PC via the graphical user interface which is part of the INSIGHT 7000 system.
The L700 is ideal for rural and hard to reach areas, as it provides the details of fault activity that shows the location of the fault without the teams having the access these remote locations – it removes the guesswork!
