The Power System setpoints path is:
\ SETPOINTS \ S2 SYSTEM SETUP \ POWER SYSTEM
NOMINAL FREQUENCY:
60 Hz
Range: 25 to 60 in steps of 1 Hz
Enter the nominal power system frequency. This value is used as a default to
set the optimal digital sampling rate if the system frequency cannot be mea-
sured as there is no voltage available at the bus voltage phase A input termi-
nals.
PHASE SEQUENCE
ABC
Range: ABC, ACB
Enter the phase sequence of the power system.
COST OF ENERGY:
5.0 ¢/kWh
Range: 1.0 to 25.0 in steps of 0.1 ¢/kWh
Kilowatt hour power usage is converted to a cost of energy using this setpoint.
The cost of energy charged by a utility is usually a variable rate depending on
total energy consumed or other factors. Enter an estimated average cost in
cents per kWh. Approximate energy cost will be determined by the relay, pro-
viding a value useful for budgeting purposes.
