I have measured kW on each phase of my circuits in a panelboard. How do I determine the kW total on one 3 phase circuit?
Do I sum the three phases readings together? or average them?
Example:
So what would my breaker kW total be for breaker 2 for example? 9kW or 3kW?
Do I sum the three phases readings together? or average them?
Example:
Phase Reading | Breaker | Breaker | Phase Reading |
A:3, B:4, C:3 | 1 | 2 | A:3, B:3, C:3 |
A: 5, B:5, C:5 | 3 | 4 | A:3, B:4, C:3 |
A:1, B:1, C:0 | 5 | 6 | A:3, B:4, C:3 |
A:1, B:1, C:1 | 7 | 8 | A: 5, B:5, C:5 |
All zero | 9 | 10 | All zero |
