| A power distribution network system is provided. The system includes a plurality of metering devices configured to generate load side data, a plurality of processing subsystems that is in operational communication with at least one of the plurality of metering devices and a central processing subsystem, wherein the plurality of processing subsystems is configured to receive a subset of the load side data from at least one of the plurality of metering devices, receive supervisory controls and supervisory conditions from the central processing subsystem, determine whether one or more of the supervisory conditions are satisfied based upon the received subset of the load side data, and execute one or more of the supervisory controls based upon the determination whether one or more of the supervisory conditions are satisfied, wherein each of the plurality of processing subsystems is located at a load bifurcation point in the power distribution network. | ||||||

| The system and methods of the present invention generally include retrofitting at least one shrouding device that is associated with a meter reading module drive shaft that operates within a meter reading module housing. Including at least one shrouding device about the meter reading module drive shaft substantially reduces rotational wiggle or play of the drive shaft within the housing of the meter reading module during operation by reducing the void between an outer surface of the drive shaft and an inner surface of a drive shaft channel of the housing, and/or by reducing the effects of tapered shafts or drive channels. In one embodiment, the shrouding device includes a sleeve device substantially secured around a portion of the shaft confined within the drive channel during rotational operation. In alternative embodiments, at least one bushing is secured to the shaft at one or more predefined portions of the shaft. | ||||||

| An existing cylindrical housing for a chart recorder is utilized as the housing for a magnetic tape recording unit. The cylindrical housing includes a terminal block, three mounting spacers, six threaded cover plate fastening bosses and a housing cover. The magnetic tape recorder unit is of circular configuration having a size and shape to be received in the housing without requiring the removal of the three mounting spacers, while using one spacer for back support. The unit includes mounting holes oriented with four of the six existing cover plate fastening bosses. A cable assembly connects the tape recorder to the existing terminal block for direct recording of power usage.
