The underlying physics of IEC 60437 revolve around the generation and measurement of high-frequency currents produced by corona discharges. The Mechanism of Corona Generation
IEC 60437 is an international standard that defines the precise procedures for measuring the radio interference characteristics of high-voltage insulators. It applies to insulators used on AC overhead power lines and substations operating at voltages above 1,000 V. iec 60437 pdf
