IM300 Intelligent Power Monitoring Instrument
Phase voltage Uan (valid in 3-phase,4-wire system)
Phase voltage Ubn (valid in 3-phase,4-wire system)
Phase voltage Ucn (valid in 3-phase,4-wire system)
Total reactive energy(Eq)
Note 1: In the 3-phase 3-wire system, the data in 42009~40011 are
invalid and value is 0.
Note 2: The correspondence between the above data (Ai) and the
actual value is:
Voltage: U = (Ai / 10) × (PT1 / PT2), Ai is an unsigned integer, unit:V.
Current: I = (Ai / 1000) × (CT1 / CT2), Ai is an unsigned integer,
unit:A.
Zero-sequence current: In = (Ai / 1000) × (CT01 / CT02), Ai is an
unsigned integer, unit:A.
Active power: P = Ai × (PT1 / PT2) × (CT1 / CT2), Ai signed integers,
unit:W.
