به دلیل عملکرد رله ارت فالت می باید تست و بازدیدهای لازم از ترانس بعمل آید. در زیر برخی توصیه های معمول در این زمینه آمده است. 1- Insulation resistance-dielectric absorption testlng. The insulation resistance test is probably the best known and most often used electrical test for insulation. It is used primarily to detect low resistance paths to ground or between windings that result from carbonization, deterioration, or the presence of moisture or dirt. It will not indicate the actual quality of the insulsion, but when conducted under controlled condltions, with the data compiled for a number of service intervals, trending data can be developed, and definite conclusions can be drawn as to the insulation
