Title
Measuring relays and protection equipment – Part 22-1: Electrical disturbance tests – 1 MHz burst immunity tests
Relais de mesure et dispositifs de protection – Partie 22-1: Essais d’influence électrique – Essais d’immunité à l’onde oscillatoire amortie 1 MHz

Scope:
This part of IEC 60255 is based on IEC 61000-4-12, referring to that publication where applicable, and specifies the general requirements for 1 MHz burst immunity tests for measuring relays and protection equipment for power system protection, including the control, monitoring and process interface equipment used with those systems.
The objective of the tests is to confirm that the equipment under test will operate correctly when energised and subjected to repetitive damped oscillatory waves such as those originating from closing or opening circuit breakers or disconnectors in high voltage substations or power plants.
The requirements specified in this part of IEC 60255 are applicable to measuring relays and protection equipment in a new condition and all tests specified are type tests only.
The object of this standard is to establish:
– definitions of terms used;
– test severity levels;
– test equipment;
– test set-up;
– test procedure;
– criteria for acceptance;
– test report.
