A system includes power harvesting circuitry in combination with energy storage and conversion circuitry. The power harvesting circuitry may be configured to respond to energy generated by rotary machinery having at least condition being monitored by at least one component having at least one electronic circuit, and provide harvested power. The energy storage and conversion circuitry may be configured to respond to the harvested power provided from the power harvesting circuitry, and provide stored and converted power to the at least one component for monitoring the least one condition of the rotary machinery.

A protection relay is disclosed that generates a trip signal to operate a circuit breaker in case of a fault condition. A first module provides measurement and analysis of power parameters of the power line connecting the power equipment that is being protected, the protection being provided by generating a first trip signal for operating a circuit breaker connected in the power line. One or more second modules can boost performance of the protection relay by measurement and analysis of power parameters-to generate a second trip signal for operating a circuit breaker connected in the power line. The first trip signal and the second trip signal are logically combined to generate a trip signal that operates the circuit breaker.
