A transformer is an electrical equipment that helps in varying the voltage of the electric current. This stepping up and stepping down of the voltage is especially important when a safe amount of electric current is required to be supplied to the end users. In order to ensure continuous and safe transmission of electricity from the power generation plant to the end users, the transformers utilized for this purpose have to be monitored continuously in real time. This is achieved by installing a transformer monitoring system within a transformer housing. Requirement of a transformer monitor is especially important when faults and anomalies within the grid or circuit have to be detected before the complete breakdown of the transformer occurs.
