Setting And Displaying Locus Diagram - Toshiba RSM 100 Instruction Manual

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
･ DGR Coordinate
② On the [Set] menu, click [Locus Setting].
