About WEM3080TR

WEM3080TR: WEM3080T+reactive parameters

Reactive parameters includes both Q(KVAR) and KVARh of the three phase.

Q(Kvar): reactive power, positive value means inductive, negative value means capacitive

KVARh: reactive energy, each phase contains two KVARh, KVARh for inductive load and KVARh for capacitor load.

API: reactive measurement

Firmware Version requirements

"i.75.88.66" or higher

Turn on the reactive measurement

Normally, the reactive measurement is closed, it needs to be opened manually.

/api/reactive?x=1

open the reactive measurement

Data format of the "monitorjson" after turn on the reactive measurement

After you open the reactive measurement, there will be an extra "EA" field in the JSON return. There is a "Reactive" field which contains 3 arrays in "EA"

Each element in the three arrays represents the Q value(reactive power), the inductive KVARh value, and the capacitive KVARh value of each phase.
