Specifies general requirements for power frequency 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 short duration, conducted, common and differential mode power frequency disturbances. Is based on IEC 61000-4-16.
