Research has shown that a massive 85% of disruptive failures in HV and MV equipment are linked to PD damage.

Substation failure can be devastating. Apart from creating outages, halting production and other day-to-day activity, it could cause a reportable health and safety incident. In a worst-case scenario, the outcome could even be injury or fatality.

There are two main constituents to the High Voltage (HV) grid: cables and switchgear. Gradually, over time, their insulation deteriorates until they reach one of two outcomes: replacement or failure.
