How to evaluate protection reliability based on statistical methodology and zones

How to evaluate protection reliability based on statistical methodology and zones

This note's origin is not quite ordinary, and it is worth explaining in order to avoid surprising the reader without a good reason — especially since we've talked about the method of choosing lightning arresters based on protection zones multiple times during our webinars.

Why is a compensator necessary for lightning protection?

Why is a compensator necessary for lightning protection?

Lightning protection is a system that is operated in fairly harsh conditions. The components on the roof that defend against lightning may easily reach 70 degrees or more in the summer, while negative thirty degrees is quite common in the winter. The thermal expansion effect of metals becomes evident within a temperature range of 100 degrees Celsius. Such a significant temperature change can cause an increase when hot and a decrease when cold in the running length of the lightning grid's or current collector's conductor. Temperature fluctuations will be approximately 11-12 cm for every 100 meters of zinc-plated or copper-plated steel conductor. This increases the possibility of harm to the roofing's firmly fixed lightning protection equipment.

Lightning protection of a traction substation in the Novosibirsk region

According to RD 34.21.122-87 "Instructions for lightning protection of buildings and structures" (hereinafter RD), the probability of a lightning breakthrough is a parameter characterizing the failure of a lightning rod as a protective device. It equals the number of lightning discharges into the protected structure divided by the total number of lightning discharges into the lightning rod and the protected structure. The standard degrees of reliability are 0.95 and 0.99.

A brief analysis of the requirements of the SP RK 2.04-103-2013 (Code of Regulations of Republic of Kazakhstan 2.04-103-2013) to lightning protection in Kazakhstan

A brief analysis of the requirements of the SP RK 2.04-103-2013 (Code of Regulations of Republic of Kazakhstan 2.04-103-2013) to lightning protection in Kazakhstan

Like many other countries, Kazakhstan has a set of regulations outlining the process and safeguards against lightning strikes. After reviewing it and taking into account our experience using the Russian Federation's comparable standards, we have chosen to share with you some of the features of this document. When studyingSP RK 2.04-103-2013 “Lightning protection device for buildings and structures” it becomes obvious that the document attempts to link together many European standards. The attempt is of great interest, let's take a closer look at it.

An instance of figuring out how to protect an acetone warehouse and filtration pumping station in the Samara area from lightning

As long as it creates the necessary zone of protection, a single lightning arrester (single lightning protection system) can be used to protect many structures on the property from lightning strikes. A free-standing lightning mast that has the necessary height is one of the best kinds of lightning receivers in these situations. The mast is installed into the ground using a concrete foundation. Its design accounts for the environmental loads (temperature, wind, snow, and earthquake) that the mast would encounter while in operation to ensure dependable and reliable service. The Technical Center ZANDZ.com has suggested a lightning receiver of a similar kind to safeguard an item made up of two buildings.

Lightning Protection for an Oxygen Gas Station in Krasnoyarsk

The ZANDZ.com Technical Center has participated in designing lightning protection and grounding systems for numerous medical institutions. You can see this by tags medical center and hospital. These designs usually employ the lightning protection to protect a main facility or a building of a medical institution. However, today we are going to discuss the calculation of the lightning protection made for a "non-residential," although very important, medical facility, i.e., the oxygen gas station. The ZANDZ technical specialists made the calculation in 2023.

Grounding for an Anti-Drone Grid

Grounding for an Anti-Drone Grid

It is now critical to defend vital energy and fuel industry installations against drone attacks. There are various methods for creating it, but all require a massive metal object: a grid support or the grid itself when it is made of metal. As soon as the anti-drone grid is elevated above existing lightning arrestors, it becomes very attractive for a lightning discharge.

According to the explosive zone classification in the IEC, a room located beyond the explosive zone should be considered non-explosive if there are no other factors exist that may result in explosion in the room. Lightning protection of such facilities is made according to Category II of RD 34.21.122-87 (RD). Let's consider an example of calculation of the lightning protection for this facility.

Why Increasing the Lightning Rod's Height?

Why Increasing the Lightning Rod's Height?

When developing lightning protection, sometimes, disputes arise regarding pros and cons of a higher lightning rod over the lower one. Note that we are talking about the same protected facility and the same lightning rod locations on it.
One may think that the higher the lightning arrester, the better it is for the lightning protection. But the situation is not as simple as it seems.
