3.2 Setting and Displaying Locus
Diagram
This section describes how to set the parameters required to display the locus diagram and
display the locus diagram.
《Note for Operation》
● Specify the calculation range from 20.0 ms or later from the beginning of the
waveforms.
● You can select the primary values or the secondary values for the locus diagram.
(→2.1 Setting Parameters for Measurement and Analysis ■Selecting Options)
● The locus diagram function of [Analysis] does not function correctly with models
without 3-phase voltage input. For example, the following models do not have 3-phase
voltage input:
Transformer protection relay GRT100, line differential relay GRL100 model 100 series,
G1-M series relays GRB150, GRC100, GRR100, GRF100 model 100 series and
busbar protection relay GRB100 model 100 series.
《Operating Procedure》
① On the [Set] menu, click the type of plane view that you want to display.
･ R-X Coordinate Impedance locus
･ DGR Coordinate Vector variation of current
② On the [Set] menu, click [Locus Setting].
