Abstract
Apparatus and methods are provided for handling the heating resulting from the operation of a self-powered power sensor (SPPS). The SPPS periodically switches between a sense mode and a harvest mode, each contributing to power dissipation that translates into heat, which may become a safety hazard. A duty cycle that is the ratio between the period in which sensing take place and the total time elapsed between sensing periods defines the duty cycle of the SPPS. In order to prevent overheating of the SPPS it is configured to provide a dynamic duty cycle that is higher for lower currents in the primary power wire and lower, for higher primary currents. This allows for better power dissipation of the SPPS and removing it from operation in unfavorable or dangerous conditions.
