Energy metering actual values are displayed here. The S1 PQMII SETUP ÖØ CLEAR DATA ÖØ CLEAR
ENERGY VALUES
setpoint clears these values. The displayed energy values roll over to “0” once
the value “4294967295” (FFFFFFFFh) has been reached.
• 3Φ POS/NEG REAL ENERGY: These messages display the positive/negative watthours
(in kWh) since the
TIME OF LAST RESET date. Real power in the positive direction add to
the
3Φ POS REAL ENERGY value, whereas real power in the negative direction adds to
the
3Φ NEG REAL ENERGY value.
• 3Φ POS/NEG REACT ENERGY: These messages display the positive/negative varhours
(in kvarh) since the
TIME OF LAST RESET date. Reactive power in the positive direction
add to the
3Φ POS REACT ENERGY value, whereas reactive power in the negative
direction adds to the
3Φ NEG REACT ENERGY value.
• 3Φ APPARENT ENERGY: This message displays the accumulated VAhours (in kVAh)
since the
TIME OF LAST RESET date.
• REAL ENERGY LAST 24h: This message displays the accumulated real energy (in kWh)
over the last 24-hour period. The 24-hour period used by the PQMII is started when
