Simulation
FIGURE 4–35: Setpoints Page 5 – Testing / Current/Voltage Simulation
Simulated currents and voltages can be forced instead of the actual currents or voltages
sensed by the external CTs and VTs. This allows for verification of all current and voltage
related relay functions.
• SIMULATION: Enter
ON to switch from actual currents and voltages to the
programmed simulated values. Set this setpoint OFF after simulation is complete.
• SIMULATION ENABLED FOR: Select the desired length of time that simulation will be
enabled. When the programmed time has elapsed, current and voltage simulation will
turn off. If unlimited is selected, simulated currents and voltages will be used until
simulation is turned off via the simulation on/off setpoint or via the serial port or until
control power is removed from the PQM.
• PHASE A/B/C/NEUTRAL CURRENT: Enter the desired phase and neutral currents for
simulation.
• Vax/Vbx/Vcx VOLTAGE: Enter the desired voltages for simulation. The voltages
entered will be line or phase quantities depending upon the VT wiring type selected
with the
S2 SYSTEM SETUP \ CURRENT/VOLTAGE CONFIGURATION \ VT WIRING
setpoint.
