This was a hallmark day for the Hinterland Electric distribution team. They had finally started receiving the equipment that would be used to automate major circuits on their distribution system. Frank and Bruce, Hinterland’s most senior linemen, were all set to get started on the first 20 circuits until they reviewed the installation specification provided by Hinterland’s distribution planner, I. M. Nuts.
The specification indicated 1/4 of the installs would be reclosers for sectionalizing the circuits, 1/2 would be wireless 3G and 4G modems for feeder intelligent electronic device (IED) communications, 1/8 would be substation transformer loadtap changer (LTC) controls and the remaining 20 would be the relocation of existing non-telemetered switches. Frank and Bruce knew all substations were not receiving new LTCs. How many LTC control units do they have to pick from the warehouse to complete Mr. Nuts’ specification?
