Voltage Drop Schedule Label Display and Order Dialog Box
See the Common Label and Schedule Information section for more information about using the Move Up and Move Down buttons and the Key, Label, Width, Display, and Schedule Title fields.
Values in the Key column are listed alphabetically below.
Branch Circuit Farthest Device Distance: The distance to the farthest device on the branch circuit.
Branch Circuit Wire Size: The size of the phase conductors on the branch circuit.
Device: The distribution equipment to which the row of fault information corresponds. Devices are listed in the order they are connected, starting at the utility. Devices that are connected to other devices are indented to indicate their relationship. If the names of the devices extend beyond the edge of the column because of the indentation, increase the width of the column.
Feeder Length: The length of the feeder to the device.
Feeder Voltage Drop: The voltage drop on the feeder from the utility to the device.
Feeder Wire Size: The size of the phase conductors on the feeder to the device.
Maximum Branch Circuit Voltage Drop: The highest voltage drop on all of the branch circuits on the device.
Specific Feeder Voltage Drop: The voltage drop on the feeder from the upstream device to the device.
Total Voltage Drop: The Feeder Voltage Drop plus the Maximum Branch Circuit Voltage Drop.
