The primary power system voltage is sometimes different than the PT Primary setup register value; i.e.
when the PT Primary is used to indicate winding ratio rather than
primary voltage.
when the PT Primary is used to indicate winding ratio rather than
primary voltage.
Nom Volts must be set to enable Power Quality functions. Most applications are
served by the default values entered into the module’s registers, but if you want to
fine-tune Sag/Swell detection, try adjusting the Swell Lim and Sag Lim values.

If the Sag/Swell module’s
Nom Volts
setup register is set to zero, all Power Quality functions of the 9350
meter are disabled. That is why Nom Volts is typically set when the meter is put into service. If
Nom Volts
has not been set, enter a value for your power system’s nominal voltage (for example, 120, 277 or 347).
Data Logging Setup
The data recording frameworks contain Data Recorder modules, Waveform
Recorder modules, and Periodic Timer modules. Data Recorder and Waveform
Recorder modules are responsible for logging the power system data. The Periodic
Timer modules control the recording frequency of the recorder modules to which
they are linked.
