"The world doesn't have enough power generation capacity to meet its needs."
Preventative maintenance can reduce blackouts and power loss on high voltage equipment, which results in minimizing power losses and hence increased power available for sale and revenues.
Under high load on transmission and distribution infrastructure, localised hot spots limit capacity and can cause black-outs due to failure.
One of the other "Power Loss" causes, which can be minimized through inspection to verify lines are installed as designed and preventative maintenance inspections to find lightening and other in-service physical damage.
This Power Loss is due to Corona - which has insignificant heat, but does have UV light emission.
Corona occurs where high local electrical field strength ionises air, resulting in Ozone and Nitric acid formation, audible noise, RF interference and UV emissions - all of which are destructive to electrical infrastructure or surrounding equipment.
When the elecrical field intensity exceeds the insulation (air, oil, solid) breakdown strength between two electrodes, sparking can occur which will generate UV emissions and very slight heating of the terminal points and or surface.
When the insulation strength is broken down power arcing occurs, this is a plasma of the air or insulating material with destructive heat (as hot as the sun).
The Corona UV emissions can be visualised with daylight or low-light Corona imaging cameras.
The Heat and Light emissions of Power Arcing, can be seen with a corona and infrared imaging camera.
