condition of all of them ranges from very good to good, whichwas to be expected because these transformers are fairly new.The health condition of one transformer that was installed in1970 is very bad because it is fairly old. The installation datesof the remaining two transformers are unknown.Transformers that are in very bad condition are likely to failbefore very long because the DP is below 200 units. Thesetransformers should be replaced immediately. Transformersin bad condition have a high probability of failure but not assoon as those in very bad condition. The replacement of thesetransformers should be planned in the near future. Transformersin moderate condition do not need to be replaced in the shortterm; however, their condition does not allow them to be leftwithout any treatment. Testing of these transformers shouldbe repeated within the next few years. New transformers inmoderate condition should be investigated in order to discoverany unusual internal faults that could accelerate the aging.Since the probability of failure is very low, transformers in verygood or good condition do not require any special care beyondregular maintenance.
