Description
13 Protection and control equipment
The protection equipment and control equipment is designed customer-specifically. T
he devices are installed in the low-voltage compartment or in the low-voltage niche.
Details are given in the respective circuit documentation.
14 Voltage detecting systems
For voltage detection according to IEC 61243-5 and VDE 0682 Part 415 with the following
voltage detecting systems:
• LRM plug-in sockets
• VOIS+, VOIS R+ (option)
• CAPDIS -S1/-S2+ (option)
• WEGA 1.2/2.2 (option)
• -C1: Capacitance integrated into bushing
• -C2: Capacitance of the connection leads and the voltage indicator to earth
