Meter wiring considerations
- Direct connect voltage limitsYou can connect the meter’s voltage inputs directly to the phase voltage lines of the power system if the power system’s line-to-line or line-to-neutral voltages do not exceed the meter’s direct connect maximum voltage limits.
- Balanced system considerationsIn situations where you are monitoring a balanced 3-phase load, you may choose to connect only one or two CTs on the phase(s) you want to measure, and then configure the meter so it calculates the current on the unconnected current input(s).
- Neutral and ground currentThe fourth current input (I4) can be used to measure current flow (In) in the neutral conductor, which can then be used to calculate residual current. The meter refers to residual current as ground current (Ig).
