ENSURING SAFETY IN OPERATION OF DISTRIBUTION NETWORKS

Abstract

In accordance with the requirements of the current Electrical Code, all facilities receiving electricity from a centralized power supply system must be provided with the necessary reliability of electricity supply. This is particularly true for oil and gas facilities. Disconnecting these objects from the power supply network even for a short period of time can lead to accidents and bring great material and moral damage. Even if the equipment is not directly struck by a lightning, an electromagnetic pulse between the clouds and a distant lightning strike to the ground can still occur. The article presents a lightning protection device — the «Grozozaschita» installation, which is being tested at the Kiengop oil fi eld in the Udmurt Republic and installed on a standalone support in the area of CTS-6/0.4 kV, taking into account the confi guration of the 6 kV electric network at a 110 / 6 kV substation. A «Grozozaschita» installation is usually located on a hill at some remote distance from important infrastructure facilities. The operation principle of the installation is based on creation of an artifi cial lightning discharge zone. The problem with this setup is that it concentrates electric charges induced by various atmospheric phenomena. Therefore, during its operation, higher safety requirements must be observed. The designation of the main components of the lightning protection system and their functional purpose are described. During the operation of the device, no lightnings struck the equipment of the Kiengop oilfi eld and power transmission line, and there were no dangerous eff ects from lightning surges. Thus, protection of all electrical equipment has been enhanced, both against voltage drops and sudden voltage surge and pulses.
