Abstract :
One application for wireless sensor networks (WSN) is the condition monitoring of high voltage power transformers to actively monitor, predict and identify causes of failures. This paper details a prototype design and testing of a hybrid power management system for a wireless sensor mote. The sensor mote, mounted on the outside of a high voltage transformer, utilizes a piezoelectric cantilever to generate electricity from the transformer tank vibration. Together with solar energy harvesting, the system allows for a battery-less self-sustained wireless sensor mote capable of autonomously monitoring its surroundings.
