CENTRON® Polyphase Meter Technical Reference Guide 63
The PC-PRO+ Advanced software lets the user retrieve Toolbox information (the same
information available by accessing the display list through the use of a magnet and magnetic
switch) on an instantaneous basis with a graphical vector diagram.
To best understand the values on the Toolbox display, one should graphically plot this
information. Before starting to manually plot the Toolbox
data, two basic definitions must
be understood about the SiteScan system.
Definition 1: The per-phase information displayed in the Toolbox
Mode is
referenced to the internal voltage and current sensors of the meter.
The meter will designate each phase by the elements. The table
below defines each element.
Phase Notation in Display
Element Used in Meter Defined Phase Phase Notation in Toolbox Display
Left-hand Element Phase A PhA
Center Element Phase B PhB
Right-hand Element Phase C PhC
The figure below shows how the wiring of each element determines the phase notation used
by the meter. (socket view)
