The core objective of IEC 60060-1 is to define how to structurally stress an insulation system to verify its dielectric integrity. Rather than evaluating operational efficiency, it validates whether a component can survive unexpected overvoltages like lightning strikes, switching surges, or sustained power-frequency rises.
Modern versions of IEC 60060-1 include updated math regarding measurement uncertainties and the calibration of voltage dividers and oscilloscopes.
