Transformers \u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u20ac\u0153 Dry and Oil<\/h4>\n
Every year. Examine the transformer tank and bushings for evidence of leakage.\u00c3\u201a\u00c2\u00a0 Inspect the bushings, insulators for broken or damaged parts, signs of overheating or arcing, or tracking. Clean all bushings, insulators, and surge arrestors of any dirt or dust accumulation. Tighten all conductor connections in accordance with manufacturer\u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u201e\u00a2s recommendations. If applicable, perform a ground resistance test.<\/p>\n
Maintenance and repair.<\/p>\n
Oil Tests<\/b><\/h4>\n
Insulating liquid samples should be taken annually and screen tested for dielectric breakdown, acidity, color, power factor, and interfacial tension. A Fault gas analysis or a Dissolved Gas-in-Oil (DGA) test conducted by a qualified testing laboratory should be performed annually. The results should be trended to track conditions and schedule maintenance, as necessary.<\/p>\n

Switchgear<\/h4>\n
Every year. During de-energized maintenance, enclosures are to be vacuum cleaned of all loose dirt and debris \u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u20ac\u009d use of compressed air is not recommended since this may cause foreign particles to become embedded in the insulation or damage insulators. Any buildup of dirt or other contaminates that will not come off with vacuuming should be cleaned with lint free rags using cleaning solvents recommended by the manufacturer. Perform a visual inspections, tighten all connections and perform maintenance tests .<\/p>\n
Oil Filtering and Degassing<\/h4>\n
The main purpose is to remove moisture, combustible gases and solid particles from mineral oils as well as natural and synthetic esters. This service is excellent degassing and moisture removal using heating elements and vacuum technology. Filtering and degassing the transformer oil will help to increase the useful life of the equipment.<\/p>\n
