BCI Test IEC 61000-4-6 Overview
The EMC Shop stocks equipment systems to give customers immediate capability to bring a bulk current injection testing setup in house. Capable of achieving 10Vrms per the IEC/EN 61000-4-6 level 4 test requirement (30V and higher available). Technical support, manuals and video overviews are available to shorten the learning curve and get you up and testing efficiently.
Setup & Procedure BCI Testing to IEC 61000-4-6
When using clamp injection, the AE setup shall present the common mode impedance as closely as possible (see Annex H in IEC 61000-4-6). Each AE used with clamp injection shall represent the functional installation conditions as closely as possible. To approximate the required common mode impedance the following measures need to be taken.
– Each AE, used with clamp injection, shall be placed on an insulating support 0,1 m above the reference ground plane.
– The clamp shall be placed on the cable to be tested. The clamp shall be supplied with the test generator level previously established during the level setting procedure.
– During a test, a ground connection shall be made from the screen of the input port of the current injection clamp or from the earth bar of the EM clamp, to the reference ground plane.
– A decoupling network shall be installed on each cable between the EUT and AE except the cable under test.
– All cables connected to each AE, other than those being connected to the EUT, shall be provided with decoupling networks.
– The decoupling networks connected to each AE (except those on cables between the EUT and AE) shall be applied no further than 0,3 m from the AE (distance: L2). The cable(s) between the AE and the decoupling network(s) or in between the AE and the injection clamp shall not be bundled nor wrapped and shall be kept at a height of 30 mm or more above the reference ground plane (Figure 5).
– At one end of the cable under test is the EUT, and at the opposite end is the AE. Multiple CDNs can be connected to the EUT and to the AE; however, only one CDN on each of the EUT and AE shall be terminated in 50 :. The termination of the CDN shall be chosen according to the priority in 7.5.
– When several clamps are used, the injection is carried out on each cable selected for testing one by one. The cables which are selected for testing with the injection clamp but not actually exercised shall be decoupled.
When using clamp injection, and the common mode impedance requirements cannot be met at the AE side, it is necessary that the common mode impedance of the AE be less than or equal to the common mode impedance of the EUT port being tested. If not, measures shall be taken (e.g. by using a CDN-M1 or 150 : resistor from the AE to ground) at the AE port to satisfy this condition and to prevent resonances. In this procedure, only the relevant differences with those measures mentioned in 7.6 are given.
– Each AE and EUT used with clamp injection shall represent the functional installation conditions as closely as possible, e.g. the EUT shall either be connected to the reference ground plane or placed on an insulating support.
– By means of a current monitoring probe (having low insertion loss), inserted in between the injection clamp and the EUT, the current resulting from the induced voltage shall be monitored.
