GB/T 17626.19-2022 Electromagnetic compatibility—Testing and measurement techniques—Part 19:Test for immunity to conducted,differential mode disturbances and signaling in the frequency range 2 kHz to 150 kHz at a.c. power ports
Abstract
This document specifies the immunity requirements and test methods for electrical and electronic equipment against differential-mode conducted interference and communication signals from AC power ports in the frequency range of 2 kHz to 150 kHz.
The purpose of this document is to establish common and reproducible criteria for testing the immunity of electrical and electronic equipment to differential-mode conducted interference and communication signals from AC power ports. This document specifies:
—— Test waveforms;
—— Test level ranges;
—— Test equipment;
—— Test setup;
—— Test procedures;
—— Verification procedures.
The provisions of this document are intended to confirm the immunity of electrical and electronic equipment to differential-mode conducted interference from sources such as power electronics and power line communication systems (PLC) when operating under a supply voltage of not more than 220 V (phase-neutral; or phase-ground if no neutral line is present) and a frequency of 50 Hz.
The differential-mode immunity of AC power ports to harmonics, interharmonics, and carrier communications up to 2 kHz is in accordance with GB/T 17626.13.
Emissions in the frequency range of 2 kHz to 150 kHz typically include both differential-mode and common-mode components. This document only specifies immunity tests for differential-mode interference and communication signals. For common-mode tests, see IEC 61000-4-16.
