description: The aim of the work is to develop an effective protection system that can mini-mize risks and ensure reliable operation of the transformer substation. To achieve this goal, it is proposed to use a nonlinear surge limiter (OPN), which allows reducing the level of overvoltage to safe values. The main tasks of the work: 1. Analysis of existing security systems 2. Investigation of the principles of operation of a nonlinear OPN 3. Analysis of modern scientific articles on the OPN 4. Development of a TP model and investigation of overvoltageâs arising on it during switching and lightning pulses 5. Selection of the optimal OPN for TP The work uses methods of the theory of electrical circuits, the theory of elec-tromagnetic compatibility and methods of mathematical modeling. The TP is based on a BCTP with two transformers TS-630/10/0.4.Â  As a result of the work, according to the data obtained on the simulation of overvoltageâs on TP and according to the calculation of OPN parameters, the optimal surge limiter of the Tavrida Electric company OPN â PT/TEL 10/10.5 was selected.
