The research results proving that it is possible to use two values of contact resistance in the calculation of the emergency modes of the 0,38 kV feeders are presented in the article. In the metal short circuits 0,1 Ohms, and in short circuits through contact resistance 50 Ohms. The obtained data will be necessary for the experts in those cases when transient resistance isn't known precisely.
