Monitoring of Step-Down Power Transformer in 33/11kv Distribution Substation Using XBEE with API Mode

Nagham Safaa | Dr. Saad Abdalratha Makki

Abstract: Transformer is the heart of electrical power system and considered a very important and expensive device. Acoording to the importance of this equipment the need of maintain and monitoring them is essential. The transmit of information from transformer in save, fast and less cost is necessary. This paper deals with the design and construction of automatic monitoring system Free Running Sensor Node System (FRSNS) for two step-down power transformers parameters. these parameters are temperature, current, voltage and oil level. This proposal depends on XBEE capability to read sensor values and transmit them periodically. Monitoring terminal received sample data (sensor values), from all node available, this monitoring terminal designed by Matlab program version R 2018 a [9.4.0.813654]. them by using one of the most popular Scada protocol (MODBUS) these values reach to The RTU.
