4.2.2 Energy Measurements
The PMC-340 provides Energy measurements for active energy (kWh), reactive energy (kvarh) and
apparent energy (kVAh) with a resolution of 0.01 kxh and maximum value of 10,000,000.00. When
the maximum value is reached, the energy registers will automatically roll over to zero. The energy
can be reset manually through the front panel or communication.
The PMC-340 provides the following energy measurements:
3-Phase Energy
kWh Import/Export/Net/Total
kWh Import/Export of Tariff 1/2/3/4
kvarh Import/Export/Net/Total
kvarh Import/Export of Tariff 1/2/3/4
kvarh of Q1/Q2/Q3/Q4
kVAh Total
Per-Phase Energy
(Phase A/B/C):

4.2.3 Demand Measurements
Demand is defined as the average power consumption over a fixed interval (usually 15 minutes)
based on the sliding window method. The PMC-340 provides the following Demand and Peak
Demand measurements:
