5.2.6 EN 61000-4-5, Power Line Conducted Surge Susceptibility

The test sample was connected to the test equipment, as shown in Figure 5.2.6, and monitored for

performance. The test level was set and the test signal was applied between one side of the line (L1) and

ground. When an error occurs, the test level is reduced until the error recovers and then increased until the

threshold level is reached. This threshold and the error conditions were noted. If no error was detected, the

injected voltage was increased to the next test level. This procedure was then repeated while injecting into

line 2 (L2). The pulse was then applied between L1 and L2 and again in common mode from both lines-to-

ground.

Five pulses in each polarity (+), at each voltage level (0.5, 1, 2 kV) were applied in each configuration (L1-

PE, L2-PE, L1/L2-GND) and voltage level (0.5, and 1 kV were applied in L1-L2 configuration. Each pulse

was spaced approximately 30 seconds apart.
