GB/T 14598.19-2007 Electrical relays Part 22-7: Electrical disturbance tests for measuring relays and protection equipment Power frequency immunity test (English Version)
This standard is based on the concepts described in IEC 61000-4-16, referring to the applicable parts of this publication, and specifies the general requirements for power frequency immunity tests. These tests apply to measuring relays and protective devices used for power system protection, including control, monitoring and process interface equipment used with these devices. The purpose of the test is to verify that the device under test is excited at its rated frequency (such as 16 2/3Hz, 50Hz and 60Hz) and is subjected to short-term, conductive common-mode and differential-mode power frequency disturbances applied to the DC state quantity input. can work correctly. This standard does not include tests on conductors arranged between substations. The requirements specified in this standard apply to new measuring relays and protective devices. The tests specified are type tests only. The purpose of this standard is to specify: — terminology used; — test severity levels; — test equipment; — test configuration; — test procedures; — acceptance criteria; — test reports.
