Abstract

This study performed comparative analysis on 37.5 kVA Cu-Cu and 37.5 kVA Cu-A1 transformer. Current density, winding resistance, losses, efficiency, weight, dimension and cost for both transformers are compared which are based on the data specifications provided by FIrst Philec Inc. The bases for comparison are from National Electrification Administration (NEA) and IEEE Standard PC57.123-2002. The current density of both transformers are within the maximum allowable current density limit for transformers. Also, the difference between the efficiency of the transformers compared is 0.0096% which is negligible. Moreover, the windings of Cu-A1 transformer is 30.13% lighter and 43.70% cheaper than the windings of Cu-Cu transformer. The coil-to-core and coil-to-tank clearances for both transformers are above the minimum clearance requirement of 5mm. Overall, the Cu-A1 transformer is significantly cheaper and lighter and has approximately the same electrical performance when compared to the Cu-Cu transformer. As the conductor size in the high voltage (HV) side of both transformers is increased, the current density, resistance, and losses decreased. Consequently, the resulting efficiency and winding costs of both transformers increased.
