Regular analysis of the insulating liquid in electrical equipment is an important aspect of meeting BS EN 60422:2013.

The oil in electrical equipment provides three key functions:-

• Cooling: Be it forced or natural circulation the liquid carries heat away from the core to the cooling fins or outer case. Preventing equipment from overheating is an important aspect of equipment maintenance to ensure the longest possible working life of the equipment. Laboratory research found that an increase of just 8 oC halves the working life of a transformer.
• Insulation: Impregnated in solid insulation and circulating freely within the equipment the liquid plays the vital role of providing electrical protection and in the case of switchgear extinguishing arcs. Moisture and particles has a negative impact of the insulation properties of the liquid.
• Information: Data from internal events such as partial discharges, heating and cellulose degradation are all stored in the oil for professional analysis and interpretation.

Listed here are our analysis by post services, upon receipt of an order we will dispatch the required bottles via courier for the customer to fill and return.

In addition to analysis via post we also offer sample extraction kits as well as on-site services for Eden staff to attend and to draw the sample.
