Voltages:
- U
12
: voltages between phase 1 and phase 2
- U
13
: voltages between phase 1 and phase 3
- U
23
: voltages between phase 2 and phase 2
- U
1N
: voltages between phase 1 and neutral

Others:
- f: frequency
- PF* : three-phase Power Factor
- Temp: internal temperature to the protection unit
* Values shown depends on the current direction (see chapter 7); this setting modifies power
sign and nature of the reactive load (inductive / capacitive).
