1. A monitoring arrangement for monitoring power in a current path, comprising:

  • an analysis circuit, which is susceptible to loss of data in the event of a power failure, includinga sensor, disposed adjacent the power line, for sensing at least one power parameter associated with the current path,a microcomputer, responsive to said sensor, for analyzing the sensed power parameter,a non-volatile memory circuit, coupled to the microcomputer, for retaining operational data in the absence of power and for providing said operational data to the microcomputer; and

    data input means, communicatively coupled to the analysis circuit, for generating and sending data to the analysis circuit for storage in the non-volatile memory circuit wherefrom the microcomputer reads the data stored therein and uses the stored data for analyzing the sensed power parameter.
