Power transformers are used for transmission of electrical power typically from a generator or as inter-connecting transformers between an electrical grid and power station with capacities ranging from few hundred KVA to MVA. These are bulk power devices and in general operate at a near constant load.These transformers are designed to utilize the
core to maximum and will operate very much near to the knee
point of B-H curve.
Distribution transformers on the other hand are used in distribution stations.They will operate under different load conditions such as peak and low loads.All-day efficiency of a distribution transformer will be considered while designing them.Typically their capacity will be in the order of few hundreds of KVA.
