For projects where transformer and distribution functions are procured together with a defined foundation and cable arrangement.
PRODUCT ENGINEERING
Construction & operating functions
DETAIL / 01
Network-topology selection
Ring supply, dual-source supply and terminal supply have different incoming-circuit requirements. Start from the actual network topology when preparing the configuration.
DETAIL / 02
Combined electrical functions
The assembly can be discussed around transformation, metering, compensation and protection. The equipment included in each function must be stated in the supply schedule.
DETAIL / 03
Oil-immersed transformer arrangement
The described combined configuration includes an oil-immersed transformer and associated switching/protection. Cooling and terminal arrangements should be reviewed using the selected assembly drawing.
DETAIL / 04
Coordinated protection scope
Fuse and switching arrangements need to correspond to the transformer and network duty. Protective-device selection forms part of the agreed electrical scheme.
