This work describes a device, locator of breaks in transmission networks based on the Stochastic Additional A/D converter. An algorithm has been used for detection does the complete analysis of circuits within the break and locates the location of the break BEFORE the protection reacts. The time needed for this is 40-80 ms. The algorithm for calculation requires data about the type of the network, characteristic values of its parameters and values of some harmonics of signals of the voltage and electricity that are measured. They are ON-LINE extracted at every 10 ms. The stochastic additional A/D converter (SAADK) is used for the extraction of these harmonics. Simulations of the work of the device have been done on generated readings of electricity and voltage, and on real images of the break. Special attention has been paid to the analysis of accuracy of the work of the device. A theoretical error is also given in the values realized from simulations.
