Active power: P = Ai × (PT1 / PT2) × (CT1 / CT2), Ai signed integers,
unit:W.
Reactive power: Q = Ai × (PT1 / PT2) × (CT1 / CT2), Ai signed
integers, unit:var.
Apparent power: S = Ai × (PT1 / PT2) × (CT1 / CT2), Ai signed
integers, unit:VA.
Power factor: PF = Ai / 1000, Ai signed integers, no unit.
Frequency: F = Ai / 100, Ai as an unsigned integer, unit:Hz.

Note: The above correspondence between the 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.
