• EXTRACT FUNDAMENTAL: The PQM can be programmed to calculate all metering
quantities using true RMS values or the fundamental component of the sampled data.
When this setpoint is set to
nd
the 32 harmonic, when making metering calculations. When this setpoint is set to
, the PQM will extract the fundamental contribution of the sampled data only
ENABLE
and use this contribution to calculate all metering quantities. Many utilities base their
metering upon fundamental, or displacement, values. Using the fundamental
contribution allows one to compare the quantities measured by the PQM with the
local utility meter.
