Electrical substations are a part of an electricity generation, transmission and distribution system where voltage is transformed from high to low or in reverse using transformers. The general functions of a substation may include:
There are various kinds of substations namely: Transmission substations, distribution substations, collector substations, switching substations and other. Their design can vary vastly though all use similar components, all of which are prone to corona and arcing activity, that include:
The integrity of conductors’ conditions, buswork and hardware conditions, porcelain post, pin as well as bell insulators conditions, polymer insulators’ conditions, switch gears, transformers etc., can be checked with Ofil’s corona cameras. In fact, Ofil’s corona cameras can efficiently identify many of the most common failure modes of those components without outages.
Inspection for corona sources is important throughout the life time of substations, 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.
Ofil develops and manufactures UV Bi-spectral optical and digital inspection systems with embedded proprietary patented Solar Blind technology. Ofil aims at providing precise solutions for science, industry and environmental wellness. Ofil owns the brand name DayCor® that stands for Daytime Corona detection.
