Power substations Early consultation with the local Electricity Distributor is essential for agreement on a mutually approved MV/LV substation
It is a high-voltage substation used to step down voltage from transmission levels to distribution levels, typically converting 220 kV to 110 kV, 66 kV, or lower voltages.
Under the lightning overvoltage condition, through modeling and analyzing the electric field potential distribution of high-voltage components of EMU, understand
Establish the three-dimensional model of high-voltage box and its internal main electrical equipment of EMU. Under the lightning overvoltage condition, through
Network layout design needs to consider distribution of the field devices, possible cable routes, placement of the linking devices, voltage drops, potential sources of noise to be avoided, together
The one line diagram is probably the single most important document, and should contain specific design information. Sometimes this drawing is separated into two documents:
The primary systems are the high voltage, civil and structural and building elements. The secondary systems are the protection, communication and control, auxiliary supplies and the automation
