6 FAQs about [Capacitor lightning test conditions]

Does lightning surge current go through bulk capacitor positive?

As the shown in Figure 3, the lightning surge current may also go through bulk capacitor positive. If the startup cell pin is directly connected to positive directly, the lightning noise will be radiated as transmitter from the PCB track which is connected startup cell with bulk capacitor positive.

What is lightning testing current wave shape?

The lightning testing current wave shape is defined in Figure 1. For an 8x20μs waveform, T1 = 8μs and T2 = 20μs. In general, surge voltage of ±2kV up to ±16kV, with increasing step of ±2kV, is applied across AC line as well as across one of the AC line and the chassis ground of the equipment under test (EUT), ie.

What voltage should be used during a lightning impulse test?

In all circumstances, the voltage appearing during the impulse test at the other line terminals shall not be more than 75 % of their rated lightning impulse withstand voltage for star-connected windings, or 50 % for delta-connected windings. The lowest value of impedance at each terminal needed to achieve the required waveshape shall be used.

What is the standard for lightning surge test?

Currently prevailing standards for the lightning surge test are the European standard IEC61000-4-5 and the Japanese standard JEC210/212. Table 1 shows the differences between the two standards. Output impedance, Z : not defined; some equipments use 6 Ω If the surge voltage is 30kV, it can generate 5kA short-circuit current (30kV/6Ω).

Which external non-linear elements should be disconnected for a voltage test?

What type of capacitor do I need for a surge?

Capacitive Coupling via 9µF (Line to earth) or 18µF (line to line) capacitors is required for coupling surges to AC or DC power mains. These coupling capacitors are typically included as part of a Coupler/Decoupler (C/D) in commercially available Surge simulators.
