Service Overview

Nearly everything that uses or transmits electrical current gets hot before it fails. Cost effective power management is critical to maintaining the reliability of your electrical and mechanical systems. Today, nobody would argue that infrared thermography is one of the most effective proven predictive maintenance technology available to quickly, accurately and safely locate problems prior to failure. Finding and fixing a poor electrical connection before a component fails can save you the much greater costs associated with manufacturing downtime, production losses, power outages, fires and catastrophic failures. Inspections are carried out under load

Thermal Imaging / Infrared Inspections in Durban, KZN

Thermography is a valuable tool for condition monitoring in electrical systems, leading to:

  • Fewer Failures
  • Reduced down-time and lower fire risks.

High Voltage Installations

Heat is a major factor in high voltage installations. Loosening and corrosion, for example,
will over time cause the resistance of electrical connections to increase. This corresponding increase in temperature
can cause components to fail, resulting in damages, unplanned outages, and even injuries.
When left unchecked the excessive heat can cause connections to melt and break down which could result in fires.

HV inspections will detect:

  • Overheated Connections
  • Incorrectly secured connections
  • Oxidation of HV Switches
  • Insulator defects

Low Voltage Installations

Electrical systems suffer from load imbalances, loose connections, corrosion and increases to
impedance to current. Thermal inspections will help to quickly identify hot spots and determine the
severity of the problem.

LV inspections will detect:

  • Overloaded/overheated circuits
  • Corroded connections
  • Poor connections
  • Internal Circuit Breaker faults
  • Fuse damage

Some examples where our inspections are carried out:

  • Distribution Boards – load imbalances and faulty circuit breakers (inspected for electrical contractors, insurance companies and property owners
  • Powerline – overheated joints, insulator condition (inspected for municipalities and suppliers)
  • Substations – switchgear, transformers, connections etc (inspected for municipalities and suppliers)

Industrial Inspections

Thermal Imaging has become an indispensable tool in ‘Preventative Maintenance’ inspections.
By detecting anomalies usually invisible to the naked eye, thermal imaging allows corrective action to be taken before costly system failures occur. Correct Inspect uses thermal imaging cameras as a unique tool to determine when and where maintenance is needed, for mechanical installations tend to get hot before they fail. By discovering these hot-spots with a thermal imaging camera, preventive action can be taken. This can avoid costly production breakdowns or ultimately, fire.

Our Inspectors use these thermal images combined with temperature data to accurately assess the condition of the inspected equipment. All this information is compiled into report form and used to make informed decisions regarding maintenance and continuity of production.Inspections are carried out whilst the system is under load, without costly shutdowns.

Examples of inspected items:

  • Motors, Pumps and Compressors (overheating bearings, misalignment, windings)
  • Conveyor Systems (bearings)
  • Process Valves (leakage, open/closed)
  • Insulation (complete, sufficient)
  • Storage tanks (levels)
  • Lubrication Issues
