That means each insulator string or post insulator must provide over 7 meters of leakage distance along its surface—hence the use of multi-shed insulators.

When designing modern systems, engineers should now refer to: Iec 60071-3

Insulation coordination is the selection of dielectric strength for equipment relative to the voltages expected on the system. Phase-to-phase coordination is uniquely challenging because it involves two varying potentials simultaneously. That means each insulator string or post insulator

: The standard outlined how to ensure system overvoltages (switching or lightning transients) remain below the proven withstand voltages of installed equipment. : The standard outlined how to ensure system

In essence, IEC 60071-3 translates system requirements into equipment specifications. It is the standard that ensures a transformer purchased for a 400 kV grid in Europe is tested to the same rigorous criteria as one purchased for a 400 kV grid in Asia, guaranteeing global interoperability and safety.
