On-line condition monitoring and diagnostic system for power transformers, an important component of electric utility, is valuable for preventing damages. The paper focuses on the area of monitoring using wireless condition monitoring systems can be cost effectively implemented in extensive applications that were historically handled by running routes with data collectors. The result would be a lower cost program with more frequent data collection, increased safety, and lower spare parts inventories. Facilities would be able to run leaner because they will have more confidence in their ability to avoid downtime. If we consider the communication range(middle range of 100m or less), data rate (about 100kbps) and power consumption(tens of mA), candidates of wireless communication technologies adequate for power monitoring system narrow down to Bluetooth and Zigbee.
