Description
The system was developed by Siemens, and the Polish plant carries out the assembly and outfitting of the sections according to the project. The devices in the sections of one board can have different versions, fixed, withdrawable or plug-in based on 3NJ4/3NJ6. The switchgear combines incomers, outgoing feeders, motor starter sections and reactive power compensation units of up to 600 kvar. The withdrawable version suits feeders that must be replaced quickly without a long outage, and the plug-in 3NJ4/3NJ6 suits compact groups of fused outgoing feeders. The peak withstand current of 330 kA makes it possible to install the board directly next to powerful transformers or several parallel incomers.
How to choose
The Sivacon S8 is chosen when the busbar current exceeds the capability of the ZR-W with its 6300 A, or a peak withstand current above 231 kA is required. For a typical substation rated 1250–2000 A the RN-W is enough, and for small automation boards with busbars of 250–1600 A the INSTAL-BLOK is more convenient. Within the Sivacon S8 itself, the choice depends on the version of the devices and the set of functional sections.
