The paper considers the problem of accidental destruction of power lines due to external factors, which led to the de-energization of large areas for a long time. Breakdowns can be caused by both mechanical damage and natural disasters - floods and earthquakes and more. As a rule, as a result of an emergency situation, the level of energy supply of large areas decreases. An important methodological aspect in studying the quality of the electrical network is the allocation of hierarchical levels of consideration. Thus, the authors consider the lowest level of functioning of the electrical network, namely the power supply of the emergency response system. Such circumstances, in turn, can lead to the emergence and development of emergencies that lead to significant casualties and destruction. It has been established that some accidents have led to power outages for more than one day. The analysis of features of work of emergency counteraction systems which are used on objects in the conditions of damage of electric networks is carried out. Devices of emergency counteraction of domestic production which have found wide application on objects and continue to be improved and let out are considered in work. Approaches to the use of imported emergency response devices, in terms of operation and installation, are almost the same, as they must meet the requirements of those regulations that are used in Ukraine. It is established that redundancy of power supply of such systems at the expense of rechargeable batteries allows to carry out their uninterrupted work no more than 24 hours. That is, if the power supply of emergency response systems from the traditional power supply network is not restored within 24 hours, such systems will stop working, which may lead to an emergency becoming an emergency. Thus, the further work of the authors will be aimed at finding a way to back up emergency response systems in the event of a power outage from the traditional power grid for a time exceeding the possibility of power supply from the battery. Keywords: emergency destruction, emergency, power grid, emergency response systems, backup power supply.
