description: In this work, we analyze the lightning protection of substations from incoming waves from incoming lines from the point of view of installing protective devices such as nonlinear surge arresters. The results of the study are compared with the recommendations of the rules for the installation of electrical installations, focused mainly on the use of valve arresters, which are outdated.
An analysis of the lightning protection of substations was performed for voltage classes 110 kV, 220 kV using the example of standard open switchgear circuits: âTransformer-line blockâ (110 kV and 220 kV), âBridgeâ (110 kV and 220 kV). For this, on the basis of the above mentioned schemes, equivalent circuits were compiled taking into account the pulse capacities of each equipment, the parameters of the volt second insulation characteristics for the overhead line 110 kV, 220 kV, 500 kV were calculated, which were used further in the Minsk software package ". With the help of this program, indicators of lightning protection reliability, depending on various factors, are determined for dead-end and pass-through schemes of substations, namely, the grounding resistance of the supports, the distance between the protected object and the protective device, the length of the protected approach.
