This is an independent voltage input that has all the capabilities of the other voltage inputs (recording, triggering, trending, etc.). A typical use would be in synchronizing a line closure. With the Nexus® meter connected to one side of a breaker, the VAUX can be connected to the other side of the breaker, and using the real time phasor display of the meter, watch the VAUX phasor relationship to the other inputs. Another application would be to use the Aux voltage to provide you the potential from neutral to ground. This enables a user to test the grounding system of a substation or facility.
