•Current impulse generator experiments conducted at the test site are described.•Measured current waveforms in the lightning protection system are presented.•Rise time of current waveforms is observed and analyzed.•Frequency-dependent model of the lightning protection system is proposed.•Measured data and simulations of registered impulse currents are compared.
Open air experiments were conducted of impulse current distribution in the lightning protection system, supplying cable and electrical installation of a test house equipped with electrical and electronic household appliances. Impulse currents were injected from the generator into the installation. Current distributions in elements of tested system were measured with multi-channel electro-optical system. To verify the experimental results the simulations of surge current in the test house modeled in ATP-EMTP were conducted. The obtained results show a good agreement between measured and numerically simulated currents and significant influence of frequency dependent parameters of the test house elements on both the amplitude and the shape of current waveforms.
