INFRARED THERMOGRAPHY

Capture.png
  • Most problems go undetected until there is an operating failure. Electrical thermography is useful as there is no other preventative maintenance technology or technique that can identify defects such as poorconnections, over loaded cables and faulty electrical equipment as safely and as quickly, whilst causing no interruption to the normal operation of your business.

  • What Electrical Distribution Equipment should have Thermographic Inspections?

  • Substations, Transformers, Feed Poles, Power Distribution Systems, Main Switchboards,  Disconnects, Service Disconnects for Motors, Machine Control Panels
