Configuration For 120/208 3-Wire Delta System With Two Pts (Two Wattmeter Method), C-Common - GE PACSystems RX3i User Manual

Configuration for 120/208 3-Wire Delta system with Two PTs (Two Wattmeter Method),
C-Common
Grid 1 or Grid 2 Tab
3-38
The following shows a typical hardware configuration for a 3-phase, 3-wire Delta power
monitoring application with the C-Phase used as common. This example shows settings
for Grid 1; all the settings can be applied to the respective Grid 2 parameters. Note that
the offset and gain values were found on the IC694PSM001 module faceplate label and
on the IC694ACC200 terminal assembly label. The Nominal Voltage is the anticipated
Phase-to-Phase voltage in the Delta configuration. Though phase-to-ground is 120VAC,
the PTs will be connected from phase-to-phase, so the range must be set to 600VAC to
accommodate the 208V phase-to-phase.
