The relay uses three phase power quantities to determine total energy consumption. All
energy quantities can be reset to zero with the
setpoint command. Energy cost is also calculated based on the average

billing rate programmed in the
setpoint. Although billing rate structures are usually more complex, these values provide
approximate costs. Energy quantities auto-range to show units appropriate to the nominal
power.
Power quantities in the positive direction are added to the positive values; power quantities
in the opposite direction are added to the negative values.
The 750/760 is not a revenue class meter and cannot be used for billing purposes.
