	View of arc shutes of a large amperage circuit breaker The heat pattern indicates that there is no internal problem, however the temperature difference between the red phase and other phases indicates a problem. This could be due to busbar connections or an unbalanced load. The image would need to be analyzed closely to determine the source of this temperature difference.
	Top of a breaker faulty lug crimp on the white phase Common cause of burnt cables as this is on the busbar (live) side of the breaker. Maintenance is not carried out this point as frequently as areas where the equipment can be isolated. That means that the live side is more susceptible to failure. By identifying this problem at a temperature of 65* C repairs could be undertaken before damage was caused to the breaker and cable due to a annealing of the copper or damage to the breaker material.
	Internal fault on a circuit breaker Another example of an internal fault developing. If this was not identified by thermography and if left to develop further there is a high risk of electrical fire and damage to adjacent equipment.
	Back view of Panel mounted CT An example of abnormal heating inside a CT, this potential fire hazard has averted by early identification of this fire risk.
