12Mw resistance furnace power supply
This project comprised of the removal,
transfer and installation of an 11kV 12Mw 100kA transformer
rectifier unit. As part of the project the transformer and rectifier cubicles were
overhauled prior to installation at the new site. The installation
included all new control systems together with all services.
The new control system comprised an Allen
Bradley PLC together with local and remote operator interfaces.
This revised control system gave improved power output control in
a fully automatic cycle together with improved overload protection
and fault diagnostics. A new 11 kV supply together with
a new substation and vacuum switchgear was installed
as part of the project.
