IEC 60255-22-1 Measuring Relays and Protection Equipment - Part 22-1: Electrical Disturbance Tests - 1 MHz Burst Immunity Tests - Withdrawn

This part of IEC 60255 is based on IEC 61000-4-18, referring to that publication where applicable, and specifies the general requirements for 1 MHz oscillatory wave immunity tests for measuring relays and protection equipment for power system protection, including the control, monitoring and process interface equipment used with the relays and protection equipment.

The objective of the tests is to confirm that the equipment under test will operate correctly when energized 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 standard 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 state:

 	
definition of terms used
 	
test severity levels
 	
test equipment
 	
test set-up
 	
test procedure
 	
criteria for acceptance
 	
test report

Note: this standard has been replaced by IEC 60255-26
