Indication of electric energy, reactive energy and periodic energy
- Indication format
The indication format of electric energy, reactive energy and periodic energy is as follows depending on the full load power:
*1: VT primary voltage in single-phase 3-wire system is regarded as 110V.
*2: Using direct connection, replace VT primary voltage with direct voltage in calculation above.
*3: In three-phase 4-wire system, replace VT primary voltage or direct voltage with phase voltage in calculation above.
