BS IEC 62003:2020 pdf download.Nuclear power plants一Instrumention, control and electrical power systems一Requirements for electromagnetic compatibility testing
1 Scope
This document establishes requirements for electromagnetic compatibility testing of instrumentation, control, and electrical equipment supplied for use in systems important to safety at nuclear power plants and other nuclear facilities. The document lists the applicable IEC standards (principally the IEC 61000 series) which define the general test methods, and provides the necessary application-specific parameters and criteria to ensure that nuclear safety requirements are met.
The normative part of this document is limited to the testing of equipment prior to installation in a nuclear power plant to demonstrate immunity to electromagnetic disturbances and to demonstrate that the equipment does not generate excessive emissions. T esting for the generation of excessive emissions is also applicable to non-safety equipment. This document includes informative annexes which provide additional guidance and describes approaches to maintaining electromagnetic compatibility for installed equipment. The intent of this document is to provide guidance for conducting the electromagnetic compatibility (EMC) qualification testing of the equipment and does not provide guidance for the installation of the equipment to prevent electromagnetic and radio frequency interference ( EMI/RFI). However, the configuration of the equipment under test during EMC qualification testing is representative of the intended installation in a nuclear facility.
Protection against a high altitude electromagnetic pulse (HEMP) and intentional electromagnetic interference (IEMI) are outside of the scope of this document, but information can be found in IEC 61000-4-23，IEC 61000-4-24，and IEC 61000-4-25 (HEMP) and IEC 61000-4-36 (IEMI) to address these phenomena.
5 EMC test requirements
Nuclear instrumentation, control, and electrical equipment important to the safety of a nuclear plant (as defined in the IEC/IEEE 60780-323 standard) shall satisfy the requirements for emissions generated by the equipment and immunity to electromagnetic interference as documented in this document. Controlling the emissions from all types of equipment (important to safety
and non-safety equipment) is necessary to ensure that the electromagnetic environment is bounded by the test levels recommended in this standard.
Table 1 contains a list and description of the EMC immunity and emissions tests applicable to nuclear I&C and electrical equipment important to safety to be installed into a nuclear facility.These tests address the main types of electromagnetic disturbances found in a typical nuclear power plant environment and not all types of tests may be applicable for a particular piece of equipment or installation. Adequate technical justification for the elimination of particular tests should be provided in the EMC purchase specification, test plan, and/or test report. Further guidance regarding the applicability of the various tests, test levels, and frequency ranges can be found in IEC 61000-6-5 (immunity for power station equipment) and IEC 61000-6-7 (immunity for safety-related system in industrial locations).
In the case of existing and installed equipment inside nuclear power plants, the requirements defined in this document may be aligned according to the state-of-the-art for EMC qualification testing valid during the time of installation. For such equipment, operational experience may be taken into account.BS IEC 62003 pdf download.
