Distribution transformer is a component in distributing electricity from distribution substations to consumers.
Damage to distribution transformer causes continuity of customer service to be disrupted. The length of the PLN
electricity network requires a transformer to distribute electricity to serve consumers. The curves of daily peak loads
for housing, shops and factories / industries vary. The 200 kVA distribution transformer load cannot serve housing,
shops and factories / industries. The method used is the replacement of a distribution transformer with a capacity of
one stage greater or the replacement of a distribution transformer with a capacity of two levels larger. The distribution
transformer carried out by the research is a capacity of 200 kVA replaced by 250 kVA. The ability of a distribution
transformer cannot accommodate a load which will increase as an area is advanced. Observations made by calculating
the age of the transformer by assuming the annual load growth (r) = 3% = 0.3. Annual peak load (P) = 1.8 p, u increase
in oil temperature at peak load (θo = 96.21 0C; 84.16 0C). The increase in the hottest temperature above the oil cover,
the increase in the temperature of the hottest place above the oil (θg = 20 0C; 20 0C). The ratio of the load loss to the
nominal load excitation loss (Q = 3; 30). By assuming the values of these methods it can be estimated that the life of a
distribution transformer is 20 kV, a capacity of 200 kVA is 18 years | en_US |
