Features of line-unit type board
	The independent configuration per line enables the independent blocking (shut-off) of the concerned line, allowing the limitation of the day-time check or maintenance.
	Since the extension is basically made per line unit, the execution of extension or renewal in the future becomes easy.
	The surveillance section composed of S/W sequence contributes to the realization of flexible surveillance function and to the simplification of wiring through connection using the connector.
	With the failure record display attached with time and work guidance in addition to the digital/analog display of measured data made in touch monitor style using color liquid crystal, the comfortable operability gentle to human beings can be realized.
	Because of the standard unit arrangement, it is possible to use a system configuration corresponding to the wired sequence system, the ME system and other various system.

Features compared with the conventional type
	Ease in renewal	Extendibility	Maintainability	Cost performance	Delivery term
New Line-unit distribution board
	Renewable per panel (per line)	Extendable per panel (per line)	Maintenance with limited power-off area	Cost can be reduced through standardization.	Standardization leads to shortening the delivery term.
Conventional Substation-unit distribution board
	Needs a large scale local switching.	Needs a structural plan based on future prospect.	Maintenance is basically carried out after shut down of the entire system.	Individual design per substation is needed.	Individual design per substation is needed.
