Energy Measurements

Energy measurements include:

active energy Ep
reactive energy Eq
apparent energy Es
active energy counted positively (EpIn) or negatively (EpOut), according to the configuration of register 3316 Power Flow Sign
reactive energy counted positively (EqIn) or negatively (EqOut), according to the configuration of register 3316 Power Flow Sign
active energy and reactive energy are accumulated according to the configuration of register 3324 (absolute mode by factory setting) Energy Accumulation Mode

The reset minimum/maximum command (command code = 46728) can reset the content of the energy measurement registers.

(1) Total active energy and total reactive energy are always counted positively with MicroLogic E trip unit.

NOTE:

The MicroLogic E trip unit screen displays positive values (only) up to 999 999 999 kWh. Over this value, MicroLogic E trip unit screen displays 999 999 999 kWh.
The MicroLogic P trip unit screen displays positive values up to 99 999 999 kWh. Over this value, MicroLogic P trip unit screen displays 0 and then 1 kWh.
The MicroLogic P trip unit screen displays negative values up to -99 999 999 kWh. Over this value, MicroLogic P trip unit screen displays 0 and then -1 kWh.
MOD10000 format is explained in the data type description.

The behavior is the same for reactive energy and apparent energy.
