Detail of GB/T 43527-2023

Introduction of GB/T 43527-2023

Electrical installations in ships - Electromagnetic compatibility - Optimising of cable installations on ships - Testing method of routing distance 1 Scope This document describes tests methods carried out to determine minimum routing distances in order to avoid crosstalk of fast transients (bursts). The test results may be applied to cable installations according to IEC 60092-352. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60092-352 Electrical installations in ships - Part 352: Choice and installation of electrical cables Note: GB/T 13029.1-2003, Electrical installations in ships - Choice and installation of cables for low-voltage power systems (IEC 60092-352:1997, IDT) IEC 60092-353 Electrical installations in ships - Part 353: Single and multicore non-radial field power cables with extruded solid insulation for rated voltages 1kV and 3 kV Note: GB/T 9331-2008, Single and multicore non-radial field power cables with extruded solid insulation for rated voltages 1 kV and 3 kV (IEC 60092-353:1995, IDT) IEC 60092-370 Electrical installations in ships - Part 370: Guidance on the selection of cables for telecommu-nication and data transfer including radio-frequency cables IEC 60092-376 Electrical installations in ships - Part 376: Cables for control and instrumentation circuits 150/250 V (300 V) IEC 60092-504 Electrical installations in ships - Part 504: Special features - Control and instrumentation IEC 60533:2015 Electrical and electronic installations in ships - Electromagnetic compatibility compatibility(EMC) - Ships with a metallic hull IEC 61000-4-4 Electromagnetic compatibility (EMC) - Part 4-4: Testing and measurement techniques - Electrical fast transient/burst immunity test IEC 61196-1 Coaxial communication cables - Part 1: Generic specification - General, definitions and requirements 3 Terms and definitions For the purposes of this document, the terms and definitions given in IEC 60533 and the following apply. 3.1 cable category classification of a cable depending on the purpose or the kind of voltage (power supply, signal transmission) the cable is intended for Note: Cable categories are shown in IEC 60533:2015, Table B.1 (categories 2 and 4) or in VG 95375-3:2012, Table 2, categories 2 and 5. 3.2 routing distance intermediate free space between cables or bundle of cables of different, i. e. interfering and susceptible, cable categories 3.3 routing height distance of cable or bundle of cables from reference ground (earth) 3.4 signal detector (SD) electronic equipment used for detection and indication of disturbance 4 Principle 4.1 General Electromagnetic compatibility (EMC) of electrical equipment or installations can be optimised by providing a defined distance between interfering and susceptible cable categories on cable routing. On the other hand the special situation aboard may call for such a distance to be as low as possible. With the test described in this technical report, the sufficient separation distance between cables of different categories can be quantified. Definition numbers of the cable categories used in this technical report are stated in Table 1.
