In this letter, approximations of the kernel are proposed, which do not use any special function, and, hence, are able to simplify the numerical evaluation in view of lightning-induced voltages calculations.Approximated kernelsCooray-Rubinstein formulalightningOn the Kernel of the Cooray–Rubinstein Formula in the Time Domaintext::journal::journal article::research article
