Lightning Impulse Testing

RWFE, LLC can perform two types of lightning impulse testing. The first is conducted impulse testing which utilizes an impulse current generator (low output impedance <1ohm) with output current capability exceeding 200kA. This is a standard test that simulates a lightning strike impulse directly onto the HV bus. A range of applied currents (and pulse energy) from a few kA to >200kA can be used in this testing. Our laboratory is fully equipped to provide the equipment (high voltage probes, high current transducers, Marx banks, high voltage power supplies and high voltage capacitors) and expertise required to perform and interpret the results.

The second type of testing is radiated EMI susceptibility. This testing utilizes a pulsed power type of impulse generator that produces strong radiated EMI emissions similar to a nearby cloud to ground lightning strike. This type of testing is useful for evaluating solid-state circuit susceptibility to electronic upset. Again, our laboratory is fully equipped to provide accurate field measurements at the DUT and to record such events using calibrated B-Dot and D-Dot probes.

The estimated costs for these tests are $5000/day.
