A patented modal filter (MF) with coupling conductors featuring a large number of strongly coupled signal and reference conductors is considered. For the first time, the conductive excitation of electrostatic discharge (ESD) current flowing through the circuit ground conductors of the new modal filter are modeled using quasi-static analysis in the TUSUR.EMC system. Considering the excitation of ESD in the circuit ground of the MF filter with coupling conductors. Quasi-static modeling of the time response in the frequency domain using a modified nodal method and a method of moments to calculate the matrices of per-unit-length parameters of a multiconductor transmission line. Voltage waveforms in the active and passive conductors of a MF with length of 0.5 m are presented. It is shown that, ignoring losses, the level of crosstalk in signal conductors reaches 53% of half the amplitude of the electromotive force of the ESD, while excitations of different conductors and its combinations result in different magnitudes and even polarities of crosstalk, giving the crosstalk level between conductors of 88,6%. It is reasonable to recognize a threat of such excitations to similar structures and to study it in more details.
