SONEL_UNDERGROUND UTILITY LOCATOR

Introduction: 

The Sonel LKZ series underground cable route tracer and infrastructure locator provides comprehensive support for earthworks and infrastructure projects across a wide range of industries, including energy, electrical installation, construction, railways, telecommunications, water and sanitation, heating and geodesy. The system consists of the LKN transmitter, LKD detector and LKR,  A-Frame detector. The LKN introduces a locating signal into an underground object, while the LKD traces the signal along the object to determine its route. The LKR, A-Frame enables the detection and precise location of underground cable grounding points and faults. The position and route of the traced object or fault can be determined by monitoring compass readings and detected signal strength. Combined with the Sonel LKZ Mobile application, the system allows users to trace cables, record routes, mark fault locations and document measurements directly in the field. The Sonel LKZ Mobile application works with the Sonel LKD and LKR detectors. It provides a convenient way to record traced routes on a mobile device, including GPS positions of way points and additional measurement data. The application offers: Live positioning and route preview, Measurement of the distance to a selected waypoint, Recording and storage of traced routes, Export and sharing of routes with other mobile devices and users, Reading previously recorded routes from the device memory, Preview of all recorded measurement parameters, Merging of multiple routes , Adding notes and attachments to routes and measurement points,  Recording and sharing of fault locations and field documentation. 

The Sonel LKZ system can operate in both passive mode, without the LKN transmitter and active mode, using the transmitter for enhanced and controlled signal tracing.

In active mode, the tracing signal can be introduced in three ways:

• Galvanic: Direct connection to the traced object using crocodile clips and test leads 
• Clamp: Inductive signal injection using a dedicated clamp 
• Inductive: Contactless signal injection using the transmitter’s internal antenna 

The system can be used to locate and trace a wide range of underground infrastructure, including:

• Power cables and power cords 
• Control and telecommunications cables 
• Underground lightning protection systems 
• Cathodic protection systems 
• Water and sewage networks 
• Fuel and gas pipelines 
• Heating systems and pre-insulated pipes 

When used with the LKR A-Frame, the system also enables:

• Precise location of cable grounding points 
• Detection and localization of cable damage 
• Identification of faults along the indicated azimuth 

Overall, the Sonel LKZ series combines reliable underground infrastructure detection with digital route documentation, making it a practical solution for locating, tracing, fault detection, and field reporting across a wide range of underground utility applications.
