Electrical Fault Detection and Repair in Porto – Specialized Service for Businesses and Industries

When an electrical problem arises in commercial, industrial, or large residential properties, finding the exact source of the fault can be a major challenge.

At Servilar, we offer a specialized electrical fault detection and underground cable repair service in Porto, using advanced technology to identify and fix issues without unnecessary excavation.

Common Electrical Issues That Require Fault Detection

In factories, warehouses, large residential properties, and industrial facilities, electrical faults can remain hidden for kilometers of underground cables. If your system is experiencing:

Frequent power outages with no apparent cause
Localized short circuits affecting operations
Overheating of underground electrical cables
Unusual energy consumption or efficiency loss
Lighting failures or industrial electrical system malfunctions

Then, you may have a fracture or fault in your electrical cables, which requires specialized equipment to be precisely located and repaired.

How We Locate Electrical Faults in Underground and Industrial Cables

We use advanced techniques and high-precision tools to detect electrical faults, minimizing downtime for your business:

Time-Domain Reflectometry (TDR) – Precise Cable Fault Location
This method maps the cable’s length and identifies the exact point of failure, detecting short circuits, insulation failures, or hidden physical damage.

Voltage Injection for Hidden Electrical Fault Detection
This method helps us identify current leaks and areas of abnormal resistance within the circuit.

Thermal Imaging and Electroacoustic Inspection
We use thermal cameras to detect overheating spots and electroacoustic sensors to listen for signs of failure inside underground cables.

Underground Cable Tracing Without Digging
We use electrical cable trackers to map the exact route of underground installations, reducing risks and repair costs.

Electrical Cable Repair in Porto – Fast and Efficient Service

Once we have precisely identified the electrical fault, our team performs cable repairs using safe techniques, ensuring your system is fully operational again.

We offer:

  • Repair of fractures and damage in electrical cables
  • Insulation and replacement of compromised cable sections
  • Correction of short circuits and overload failures
  • Post-repair testing to ensure safety and efficiency
