The standard is not a light read—its tables, annexes, and formulas require careful study. But the investment pays off the first time an insulator string withstands a salt-storm that would have tripped a non-compliant design. The standard is not a light read—its tables,
Insulation co-ordination is the process of selecting the dielectric strength of equipment in relation to the voltages that can appear on the system, taking into account the characteristics of protective devices. For AC systems, IEC 60071-1 and IEC 60071-2 are well-established. However, HVDC converter stations exhibit fundamentally different stress characteristics: For AC systems, IEC 60071-1 and IEC 60071-2
