PROTECTION OF MV AND LV NETWORKS AGAINST LIGHTNING, PART I: Common Topics
This brochure presents basic information and principles related to lightning protection of Medium Voltage (MV) and (LV) networks. The present material constitutes the first part of a 3-part guide. Parts 2 and 3, to be published later, will deal specifically with the application to MV (Part 2) and LV (Part 3) networks. This part provides first a survey of different sources of overvoltages, as well as a review of the most widely accepted and well established methods of evaluating the expected rate of direct lightning strokes and induced lightning overvoltages. The document describes in addition the characteristics of lightning overvoltages, general characteristics of surge protective devices, and earthing systems
Protection of Medium Voltage and Low Voltage Networks Against Lightning Part 2: Lightning protection of Medium Voltage networks
Overvoltages due to direct and indirect lightning events depend on several factors and are characterized by complex wave shapes. For this reason numerical codes have been developed, aiming at the
evaluation of the lightning overvoltages on realistic distribution line configurations. These tools are of fundamental help in the protection scheme design and the insulation coordination of actual distribution
systems, as well as in evaluating the overvoltages transferred through distribution transformers to the low voltage part of the system.
The basic information for designers of lightning protection of MV and LV networks has been presented in the part 1 of this guide. This second part presents an application of the basic information to the lightning protection of MV networks containing overhead lines3.
This part of the guide applies primarily to MV networks with system voltage in the range from 1 kV to 36 kV. It is relevant for higher system voltages as well, but it becomes gradually less relevant when
the system voltage increases. It is thus not possible to specify an upper limit for the system voltage, but the guide should not be used for system voltages above 50 kV
