As an Engineer you have been contracted by a power distribution company to investigate the causes of frequent transformer failures in its network. In the course of your investigation you came across the following: The Transformer installed in urban area failed within the warrant period of 3 years; the diagnostic results showed failure of one phase of the High Voltage (HV), It was further observed that this failure was causes by Overheating and overloading of that phase which caused burning of both HV and Low Voltage (LV). Explain what could be the cause(s) of this overload and the implications it could have on other equipment in the Transformer
