Rated VoltageInsulating MediaDegree of ProtectionCompartments, Accessibility and Service ContinuityIAC (Internal Arc Classified) SwitchgearThe rated values for the insulation level of a switchgear installation must be selected on the basis of the requirements of the system at the installation site from the selection tables in IEC 62271-1. Table 1 shows the selection values for the range of rated voltages up to 52 kV. The voltage values “over the isolating distance” only apply for switching devices with which the safety requirements for the open contacts of disconnecters must be met. Table 1 lists two value pairs that can be selected for the rated lightning impulse voltage level for almost all rated voltages. Table 1 – Rated voltages and insulation levels in the medium voltage range Go back to Contents Table ↑ When making the selection, the degree of danger from lightning and switching overvoltages, the type of neutral treatment and, if applicable, the type of overvoltage protection should be considered.
