TEGG Service Old

Tegg Banner

We want to test the electrical infrastructure of your building without operational downtime. 

The introduction of our TEGG service means we can compile comprehensive compliance reports, using specialist non-intrusive equipment, without operational interruption on your energised system.

Combining this service with Lantei’s specialist electrical testing service, forms the optimal compliance solution.


Asset Management

A digital reference image and thermal image is taken for each individual component as well as issuing a unique reference number in the software. To this, the full component name plate data is recorded, enabling quick reference for site location and spares ordering through the asset management software’s search facility.

Visual Inspection

The entire component will be inspected, determining adjustments to be made and to ensure it is operating within its specified limits. Our engineer will identify areas of corrosion, safety hazards and regulation violations throughout their inspection process.

Ultrasonic Testing

Measures sound waves and/or vibrations that are above audible sound (16-18 KHZ). Supplementary to Thermal Imagining, this process discovers arcing, vibrations and tracking if present within the electrical system.

Infrared Technology

Measures and identifies spiking temperatures that exceed the limit for that specific electrical source. High resistance electrical connections, current overload, defective circuit breakers and/or defective insulator conditions. This service is used to reduce the risk of component failure.

Voltage & Current Analysis

Captures Total Harmonic Distortion-Voltage (THDV) and Total Harmonic Distortion-Current (THDC) that exceed IET recommendations. This service determines whether your harmonic distortion is within tolerance levels. This analysis minimises the risk of damage to microelectronic equipment, transformers, circuit breakers, and motors.

Energised & De-energised Maintenance

It is recommended that a Preventative Maintenance Programme is reviewed and carried out regularly, while the electrical distribution system is energised under normal load. This provides a more accurate representation of how the electrical system operates while being used.


  • Using TEGG software, we compile a complimentary asset register, identifying every electrical component.
  • All switchgear is thermally imaged and ultrasonically tested followed by a power quality analysis.
  • Electrical testing is carried out with no operational downtime. The report is uploaded to the portal.
  • A bespoke planned maintenance programme is tailored to your site requirements and budget.


  • Testing without shutdown
  • The service includes an Asset Register
  • Prevent electrical & IT systems failures
  • Prevent business outages
  • Prevent electrical fires
  • Prevent early failure of equipment
  • Reduce utility costs
  • Provide a safe and healthy working environment
