9. Appendix
9.2. A List of Examples for Incorrect Wiring Display
9.2.1. 3-phase 4-wire System
Note1: The above examples for incorrect wiring are typical. Extreme cases are excluded such as burnout or destruction of the instrument,
VT, or CT caused by voltage application to a current circuit or current application to a voltage circuit.
Note2: The active power polarity may be displayed in reverse depending on the load status (low power factor, unbalanced load) even if the
connection is correct.
