Ofil's daytime corona cameras are used for inspection of high and medium voltage substations. Inspection for corona sources is important throughout the life time of any substation, and in particular during commissioning.

Ofil's daytime corona cameras enable pinpointing sources of corona partial discharge and designate thereby faulty components and components in deteriorating stages.

Using Ofil's systems in substations can prevent outages and flashovers and reduces significantly the maintenance costs.
