Busbar components

For 8DA10 switchgear, there are the following busbar components:
• Plug-in, metal-enclosed busbar voltage transformers, with or without three-position
disconnector
• Busbar current transformers
• Busbar connection with cable plug, with or without three-position disconnector
• Busbar connection with solid-insulated bar connection, with or without three-position
disconnector
• Busbar connection with gas-insulated bar connection, with or without three-position
disconnector
• Busbar earthing switch
• Make-proof busbar earthing switch
• Capacitive voltage detecting system according to IEC 61243-5 or IEC 61958
• Top-mounted bus sectionalizer
This chapter describes the basic assembly operations for busbar components by means of
several examples.
Example: Busbar voltage transformer
Depending on the design option of the switchgear, the voltage transformer is available with
or without three-position disconnector.
