The utility company, Kenya Power, loses an average of three hundred distribution transformers in a month. This has a negative economic impact on both the supplier and the customers. It has been observed that the three transformer workshops of Kenya Power have an average output of one hundred and fifty transformers per month. Hence it takes several days to return the affected customers back to supply
The main aim of this project is to monitor, control and protect distribution transformers from malfunctioning due to faults caused by overheating, overloading, fall in oil level, and voltage surges. This will help Kenya Power by ensuring that their distribution transformer faults are immediately realized and reported to the concern department, hence being able to maintain and repair a transformer before total breakdown and thus reducing the total number of transformer failures. This will ensure that the number and duration of power interruptions to the customer is decreased, maintenance cost reduced and also save time.
This system will be implemented using microcontroller and global system for mobile (GSM) communication technology which are very efficient and cost effective. The microcontroller will interact with sensors to continuously monitor the voltage, load current, temperature and oil level of the transformer. As the values of current, voltage, temperature and oil level of the transformer increase from the preset values, the microcontroller through GSM will inform the repair and maintenance personnel for appropriate action to be taken. The voltage, current and temperature values will be displayed on an LCD display and the kind of the fault will be indicated using LED indicators .An increase in temperature above the benchmark will turn a fan to cool the transformer. The microcontroller will also send appropriate control signal to appropriate circuit breakers that will disconnect the transformer in case of acute faults such as a short-circuits or excessive fall in oil level and initiate an alarm.
