2.3.7 Interconnected Mesh Corners Arrangement
An interconnected mesh corners scheme gives maximum security against
busbar faults (see Fig. 2.13).
2.4 LOAD BREAK SWITCHES
In distribution systems, up to 33 kV are used to switch on loads under nor-
mal operating conditions. These switches can be used to make on short cir-
cuit current but do not brake on short circuit currents.
