Power Holding Company of Nigeria (PHCN) has made use of transformers in various ways to supply electricity. But most of these transformers do pack-up after a period of time due to poor maintenance, lack of testing instruments, lack of protective devices, etc which lead to various faults in transformers. Most of these problems have been solved in generation and transmission levels, but much is yet to be done in the distribution level since most of the consumers know little about electricity. Overloading of transformers, accident on poles & lines, back feeding of lines, bad connections etc result in possible transformer failures. Tests and maintenance are performed to put a transformer back in operation but it requires much period of time that will put the affected consumers off. PHCN needs to replace the faulty transformer in order to give continuous supply pending the repair of the faulty one.
