Thermography

Thermographic Inspection is the most powerful, remote, non-contact, on-line inspection technique available today for establishing the integrity and safety of all electrical installations. In fact, in many developed countries around the world this technique is now a mandatory procedure.

Thermography involves the measurement of infra red energy radiated from a surface to determine the temperature of the surface. This allows testing without removing equipment from service.Thermography is particularly beneficial in detecting electrical faults, however Vipac also use thermography to identify mechanical issues with rotating machinery and apply customised solutions to a broad range of problems.

Many electrical installations are only inspected once a year. This typically involves a visual inspection and tightening specific connection points such as a cable to busbar connection. In some cases electrical inspections are not even carried out until there is a failure, which is usually revealed by a power outage or even worse by an overheated component catching fire.

By utilizing Thermography on a regular basis, usually twice a year depending upon the installation, we provide a complete thermal picture of the total installation. Thus identifying existing defects  and any developing problems, enabling their early and economic rectification. This will prevent power failures or the consequences of an electrical fire.

We can thermally resolve temperature variations as small as 0.08°C and spatially to 1 milli-radian.

Areas to monitor should include:

  • Low Voltage Transformer Units
  • Low Voltage Switchboards
  • Capacitor Banks
  • MCCB Panels
  • MCB BD Panels
  • Busduct Riser Mains

Vipac’s certified thermographic inspections team provides independent analysis of systems giving building managers better control over  electrical maintenance operations.

Thermographic inspections can be scheduled to coincide with the provision of services requiring other site visits.
