Energy
Meter supports excellent energy metering functions as follows
：
·Bi-direction energy metering
·Four-quadrant reactive energy metering
·Tariff energy metering (TOU)
·Spare energy metering
All the values of energy are calculated on the basis of secondary value,
minimum resolution of which is 1Wh of 1varh. Provided the external PT or CT
is connected, the value of primary energy increases or decreases by
1Wh(1varh) multiple rate.
The maximum value of saved secondary energy is 2147483647 Wh, and the
maximum value of displayed primary energy is 99999999999 kWh (99.9
billion kilowatt). Users can manually reset the energy data as per the specific
needs.
Spare Energy
Signal coming from a Generator. when the main line is cut off and a
generator gives the power to the installation. The meters must measure and
