Setting Procedures; Step1: Use Settings [Ch Use_Ch*] - Toshiba GRB200 Instruction Manual

Setting procedures

3
It has been discussed about the settings with regard to bay arrangements in the preceding
chapter, but the user may concern the setting procedures for actual busbar structures.
An example of busbar structure is shown with a single line diagram in Figure 3-1. The figure
illustrates that feeders and couplers are structured with CHs. All CHs can have forward
looking protection-zones, but 'CH4' can have a revers looking one exclusively. We discuss about
the setting examples step by step in this chapter; the user can read the settings by referencing
the models described in
