Today’s requirement for an effective maintenance plan has never been more critical due to increasing pressure from our Clients to ensure the faultless operation of their systems.
For many Clients thermal imaging has evolved into one of the most valuable diagnostic tools to be used for Predictive Maintenance (PdM) and by utilising the most modern equipment Metricab is pleased to offer this service to our Clients.
Thermal Imaging (also known as Thermography) is the production of non-contact infrared pictures from which temperature measurements can be made. This system is used to detect anomalies often invisible to the naked eye, even while electrical systems are under load.
When a connection becomes loose there is a resistance to current that can cause an increase in temperature and subsequent failure of components, potentially resulting in unplanned outages and possible injury. In addition, the efficiency of an electrical grid becomes low prior to failure, thus energy is spent generating heat, causing unnecessary losses. If left un-checked heat can rise to a point at which connections will melt and break the circuit, as a result of which fire may occur.
Besides loose connections, electrical systems suffer from load imbalances, corrosion and increased impedance to current. Thermography will quickly locate “hot spots”, determine the severity of the problem and help to determine the urgency of repairs.
Thermography is also particularly useful for inspecting indoor and outdoor components such as Motor Control Centres, Substations, Breaker Panels, Switchgear, Transformers and Circuit Breakers.
Thermography not only detects high temperatures but can also be used to detect temperatures that have fallen below recommended levels, thus providing a very wide range of functions.
All surveys are qualified by a fully comprehensive report detailing our Engineer’s findings and recommendations for the repair of any fault.
