Abstract
U niskonaponskim (NN) instalacijama zaštitni uređaji diferencijalne struje (engl. Residual Current Device, RCD) su obavezna zaštitna mjera. Pravilnim izborom osigurava se sigurnost rada i pravovremeni isklop u slučaju kvara. Razlika potencijala koju čovjek može premostiti ovisi o uvjetima u pogonu, neposrednom okolišu te otporu na koji struja nailazi pri prolasku kroz čovjeka na putu prema zemlji. RCD uređaji moraju zadovoljiti propisane zahtjeve kako bi se smatrali ispravnim. Provedena mjerenja polučila su rezultate kojima se utvrđuje ispravnost djelovanja RCD uređaja pri različitim impedancijama petlje kvara. Primjenom zaštitnih uređaja diferencijalne struje čovjek se štiti od direktnog dodira dijelova pod naponom. Ovaj tip zaštite koristi se kao dopunska mjera zaštite pri jednopolnim direktnim dodirima. Ispitivanjem RCD uređaja potvrđuje se kako ispravnost i točnost uređaja, spojenih komponenti i zaštitnog voda utječe na sigurnost čovjeka u elektroenergetskom okruženju.
Abstract (english)
In low-voltage (LV) installations, protective residual current devices (residual current devices, RCDs) are a mandatory protective measure. The correct choice ensures operational safety and timely shutdown in the event of a malfunction. The potential difference that a person can overcome depends on the operating conditions, the immediate environment and the resistance that the current encounters when passing through the person on its way to the ground. RCD devices must meet the prescribed requirements in order to be considered correct. The conducted measurements yielded results that determine the correct operation of the RCD device at different impedances of the fault loop. By using differential current protective devices, people are protected from direct contact with live parts. This type of protection is used as a supplementary protection measure for single-pole direct contacts. By testing the RCD device, it is confirmed that the correctness and accuracy of the device, the connected components and the protective cable affect the safety of people in the electrical environment.
