The list of commissioning operations and checks is shown in Table 15 below. Initial state of VCB components
before checks: ISM - open, CM - deenergized. Main circuits of ISM shall be disconnected/isolated from the main
circuits of substation to avoid high voltage being applied to the ISM before the commissioning procedure
completion. Commissioning and maintenance is only permitted for qualified and trained personnel.
