Maximum single-phase 2-wire
current
demand
single-phase 3-wire
three-phase 3-wire
Minimum single-phase 2-wire
current
demand single-phase 3-wire
three-phase 3-wire
Maximum single-phase 2-wire
voltage
single-phase 3-wire
three-phase 3-wire
Minimum single-phase 2-wire
voltage
single-phase 3-wire
three-phase 3-wire
Average current = 1-phase current
Average current = (1-phase current + 3-phase current) / 2
Average voltage = voltage V12
Average voltage = (voltage V12 + voltage V23) / 2
Maximum value of 1-phase current demand
(The highest value after the max./min. value was reset.)
Highest value of either 1-phase current demand or 3-phase current
demand
(The highest value after the max./min. value was reset.)
Highest value among 1-phase current demand, 2-phase current
demand, or 3-phase current demand
(The highest value after the max./min. value was reset.)
Minimum value of 1-phase current demand
(The lowest value after the max./min. value was reset.)
Lowest value of either 1-phase current demand or 3-phase current
demand
(The lowest value after the max./min. value was reset.)
Lowest value among 1-phase current demand, 2-phase current
demand, or 3-phase current demand
(The lowest value after the max./min. value was reset.)
Highest value of the 1 - 2 line voltage
(The highest value after the max./min. value was reset.)
Highest value of either the 1 - 2 line voltage or the 2 - 3 line voltage
(The highest value after the max./min. value was reset.)
Highest value among the 1 - 2 line voltage, the 2 - 3 line voltage, or 3
- 1 line voltage
(The highest value after the max./min. value was reset.)
Lowest value of the 1 - 2 line voltage
(The lowest value after the max./min. value was reset.)
Lowest value of either the 1 - 2 line voltage or the 2 - 3 line voltage
(The lowest value after the max./min. value was reset.)
Lowest value among the 1 - 2 line voltage, the 2 - 3 line voltage, or 3
- 1 line voltage
(The lowest value after the max./min. value was reset.)
