Power Transmission Transformer

Power Transmission Transformer

Power transformer is used for the transmission purpose at heavy load, high voltage greater than 33 KV and 100% efficiency. It also having a big in size as compare to distribution transformer, it used in generating station and Transmission substation at high insulation level.
The distribution transformer is used for the distribution of electrical energy at low voltage as less than 33 kV in industrial purpose and 440 – 220 V in domestic purpose. It work at low efficiency at 50-70%, small size, easy in installation, having low magnetic losses & it is not always fully loaded.
