1. A method of generating electrical energy metering quantities in a multi-channel load profile recorder, comprising the steps of:

  • sensing a line current and a line voltage transferred from a line to a load during a first load profile time interval;

    generating at least one first electrical energy metering quantity based on the sensed line current and the sensed line voltage, upon completion of the first load profile time interval;

    storing the first electrical energy metering quantity in a programmable memory portion of the multi-channel load profile recorder;

    transferring the first electrical energy metering quantity from the programmable memory portion of the multi-channel load profile recorder to a storage unit located external to the multi-channel load profile recorder;

    contemporaneously with said first electrical energy metering quantity transferring step, generating, internal to the multi-channel load profile recorder, at least one second electrical energy metering quantity corresponding to the first load profile time interval from the first electrical energy metering quantity; and

    thentransferring the second electrical energy metering quantity from the multi-channel load profile recorder to the storage unit.
