2LN. 3-phase 4-line Y with 2 voltage transformers
This mode is used in some high voltage 3-phase 4-line Wye systems. It is
supposed that the 3 phases of the power system are in balance. The V2
voltage is calculated from the measured values of V1 and V3.
1LN. 1-phase 2-line
This connection is used for measurement on single phase systems.
