High voltage impulse testing

Most of the main power grids in the world represent power lines on transmission towers. They are largely susceptible to lightning strikes, which can result in a risk of damage to components in electrical substations (PS).
Loss of one or several elements can lead to local loss of tension, and thus cause consumer dissatisfaction and costly repairs. Testing transformers, surge arresters, isolators and switchgear is an important part of the process of quality control and registration of the degree of endurance of the components.
