Outlines general requirements for a radiated electromagnetic field disturbance test of static measuring relays and protection equipment with or without output contacts. Gives experience with the three tests described in IEC 801-3. The tests are to confirm that the EUT (equipment under test) will operate correctly when energised and subjected to an electromagnetic field from a radiation source operating within the frequency range 80 MHz to 1 000 MHz. The specified requirement in this standard are applicable to measuring relays and protection equipment in an unused condition, and all tests defined are type tests only.
