The joint at the end of this circuit breaker shows overheating that is caused by a failure in electrical conductivity. The potential causes are: a loose connection, material breaking in the equipment mechanism or even corrosion.
The overheating of this power disconnect caused the deterioration of the mechanical components which hindered its proper functioning. Also, constant overheating started deteriorating wire insulation. The discovery of this problem during a routine inspection allowed the operator to repair the equipment before it caused a production shutdown.
It’s the 360o photography of installations, underground access manholes, or any other element or structure. This technique allows the infrastructure operators to verify the equipment, and to check up on concrete integrity, electrical equipment and the draining system.
