5.2.3 EN 61000-4-4, Conducted Transients Susceptibility

The test sample was connected to the test equipment, as shown in Figure 5.2.3, and monitored for

performance. The test level was set, and the test signal was applied for the required time to one side of the line

(L). When an error occurred, the test level was reduced until the error recovered and then increased until the

threshold level was reached. This threshold and the error conditions were noted. This procedure was then

repeated while injecting into Neutral (N) ground and then to L and N together. Using a capacitive coupling

plate, as called out in EN 61000-4-4, the procedure was then repeated on signal and I/O lines whenever this

was applicable.
