Centrale électrique hybride à hydrogène

ENERTRAG AG

Le projet pilote de centrale hybride à Prenzlau constitue le point culminant de ce paysage relativement plat. C'est donc une cible pour la foudre. Comme tout l'intérieur du hall est classé en zone Ex, la protection conventionnelle contre la foudre ne serait pas suffisante.

Le concept de protection retenu comprend donc un système de terminaison d'air isolé, monté à distance des structures et des installations.

Gazoduc exposée à une tension alternative

Gazoduc ENSO NETZ GmbH

Le gazoduc d'ENSO NETZ GmbH est exposée à une tension alternative causée par une ligne de chemin de fer parallèle à la sienne. Cette tension alternative doit être limitée pour éviter la corrosion alternative et les dommages aux appareils électroniques causés par une surtension transitoire.

Le dispositif de découplage intelligent VCSD décharge la tension alternative temporaire et de longue durée vers une terre à faible impédance. Cela protège également les personnes contre des tensions de contact élevées inadmissibles.

Energy recovery plant

Energy recovery plant Taimeralm

Europe's most important oil pipeline uses an energy recovery plant which produces about 12% of the Austrian TAL pump stations' energy consumption.
The plant is extremely vulnerable to lightning strikes due to its location in the mountains, where the ground is stony and the soil resistivity poor. Therefore, a holistic view was taken of the lightning protection and the protection of the sensitive terminal devices.

The lightning protection concept comprises isolated external lightning protection using HVI technology, a closed meshed earthing system, meshed equipotential bonding and surge protection for the power supply, measuring, control and regulation (MSR) technology, and the telecontrol system.

Storage facilities for crude oil products

The CLH Group is a leading company on the Spanish market for the transportation and storage of crude oil products with a pipeline network of more than 4,000 kilometres and 38 storage facilities. CLH is mainly engaged in the receipt of crude oil products in the company’s facilities, their transportation and storage as well as delivery to final customers via tanker vehicles.

Permanent availability of the facilities is of utmost importance to ensure reliable fuel supply for petrol stations.
Due to the exposed location of these facilities, it is vital to install surge protective devices.

bayernets GmbH

bayernets GmbH in Munich transmits natural gas via a 1,412 km long high-pressure pipeline network in Bavaria. With a network area of 32,000 km², the company is one of the largest network operators in Germany. As part of the gas network development plan, the MONACO natural gas pipeline will increase the security of supply in the south of Germany and Austria whilst also improving network stability and flexibility. The underground pipeline with a total length of about 87 km runs from the German-Austrian border in Burghausen to Finsing near Munich. There the natural gas is taken from the high-pressure network at the “Finsing 2” transfer station and fed into the downstream supply network at reduced pressure.

BAYERNOIL

The BAYERNOIL Raffineriegesellschaft mbH with sites in Neustadt and Vohburg is the biggest refinery in Southern Germany.

BAYERNOIL puts its trust in intelligent surge protection with space-saving DIN rail-mounted devices by DEHN. 600 BLITZDUCTOR XT arresters have been installed here.

The condition monitoring system continually controls the status of arresters in order to detect imminent overload as early as possible. The necessary service measures are taken in good time, in line with the high demands BAYERNOIL has on occupational, process and plant safety.
70 DRC MCM condition monitoring systems are in use here.

Open Grid Europe - Planning

Open Grid Europe GmbH (OGE) is Germany’s leading natural gas transmitter with a gas pipeline network of roughly 12,000 km. One of the most important hubs in the natural gas grid is the OGE compressor station in Werne: here 13 pipelines come together from different directions.

Open Grid Europe relies on DEHN’s 3D planning service to integrate the lightning protection concept in the complex architecture of the site (incl. ex areas!). This guarantees the efficient configuration of air-termination devices under consideration of all parts of the facility.

Open Grid Europe - Realisation

About a quarter of Germany’s natural gas consumption flows through the Werne compressor station. The expansion of the location as a central point in the gas supply grid is also part of the grid development plan.

The lightning protection concept with a highly efficient configuration of the air-termination devices and down conductors was successfully implemented in all areas (including ex areas) using certified system components by DEHN. The preparatory 3D planning and resulting detailed drawings made huge savings on installation resources, time and costs possible.

Gascade - North Stream Pipeline

As the operator, GASCADE Gastransport GmbH is responsible for the safe and reliable operation of the natural gas receiving station in Lubmin near Greifswald.

All possible risks were assessed and economically viable lightning and surge protection measures determined as part of a risk analysis in compliance with IEC 62305-2. Conducted interference impulse could be led in from the outside via the many interfaces and cause considerable damage to the PCS.
