Earthing systems are essential to any electrical installation and lightning protection system. We have the know-how, experience and installation capabilities to perform earthing system in any situation.
A GLPS earthing rod system is generally made with deep-drawn copper wires without any joints to secure resistance stability and long lifetime. The special system provides a very low galvanic corrosion.
Estimated or fixed prices can be given for any application with any resistance requirement. For larger installations, earthing systems are often integrated into the building foundations using the concrete and reinforcement iron in combination with copper wires, special clamps and earthing termination points. A horizontal system, such as this, forms a perfect reference earthing system for a modern installation for achieving good EMC conditions and significantly higher immunity to transient overvoltages and lightning surges.
In areas with high soil resistivity, special methods must be utilised in order to achieve useful resistances and/or impedances. We have the competences to computer simulate the earthing system to determine the best layout - and our installation teams can make it happen in reality.
Standards and codes require equipotential bonding as a fundamental part of any electrical installation. Any extraneous conductive part must be connected to the main bonding system and, depending on the functionality of the installation, building or plant, supplementary bonding may be required.
Hospitals, pharmaceutical or chemical plants, banks and data centres or military installations are just a few examples of installations where equipotential bonding is essential to secure safe and stable operation.
In any lightning protection system, equipotential bonding is key to establishing protection against the indirect effects of lightning as well as securing electromagnetic compatibility (EMC) in the installation
The infield installation department has special knowledge in equipotential bonding from numerous projects, and have the engineering and installation capacity to undertake large project assignments.
Protecting buildings and living beings from lightning strikes is one of our core competences. Our infield installation team has the manpower; the know-how and the tools necessary to perform advanced lightning protection system on complex building and plants.
DS/IEC 62305 is a series of standards describing methods to follow in order to achieve efficient protection.
Any lightning protection system contains the following subsystems:
Any lightning protection system is documented by resistance measurement and regular maintenance is required.
Our specially trained technicians regular perform inspection and maintenance on lightning protection systems. During the inspection, all parts of the systems are visual checked for any loose connection, corrosion or changes in the building requiring adjustments in the lightning protection system. The electrical continuity in the system is measured with low-resistance ohm-meters and documented in inspection forms for comparing change in resistances with previous inspections.
Inspections of earthing system are performed with regular intervals to verify the resistance and functionality.
In areas with anti-static requirements, either due to risk of explosion or protection of sensitive equipment, all tools, ESD-installations earthing systems etc. must be checked annually. Our specialists are capable of performing and document such inspections.
We offer service contracts for inspection and maintenance, which secures that essential inspections are performed as planned and not forgotten. Each inspection is documented electronically and check- sheets are stored and secured. In case of damages to the installation, these damages will either be repaired immediately or reported for later corrective.
In case of lightning strikes to a building, our specialists perform a damage evaluation to define the root cause and to give recommendations for lightning protection measures.
We provide complete lightning solutions design projects that meet the requirements of professional manufacturers and that complies with the newest industrial standards and guidelines. Our engineers have many years of experience in the field of lightning protection and participate actively in international standardisation comity work, ensuring that all solutions follow relevant legislation and are based on good, sound practice.
Based on the project scope, a project team is defined including the necessary competences and ressources to complete the design assignment within the agreed time and budget. A fast way to completion is key to any project manager.
All design projects are managed meticulously following project management methods with transparent resource management and regular progress reporting.
The utilisation of the lightning laboratory is a key advantage. Here we have close access to verification at the early stages of all processes, which secures a high likelihood of a successful final verification and third party certification.
We have developed various design-tools for numerical modelling and simulations. Generally, all electrical or electro/thermal phenomena, such as lightning, can be modelled in different levels of detail in order to predict material behaviour on component level, component behaviour and impact on system level.
The tools are used comprehensively for:
Geometries ranging from varnish layers on machine copper windings (um range) to wind farm topography (km range) have been considered. The tools based on 3D/2D FEM analysis and EMTP models in frequency and time domain have been verified by comprehensive testing, and published in various scientific papers.
Lightning and switching transient analysis
We will model your installations and guide you through a lightning and switching transient analysis in order to ensure that the component voltage level is never exceeded.
We operate the world’s largest test facility for direct lightning effect testing. Here we utilise direct effect testing in accordance with various industrial, military, and aerospace standards. Our test engineers have over the years performed a wide range of verification and certification tests on coupons/panels, sub-systems, and full vehicles like wind turbine nacelles and blades. Nothing is too small and nothing is too large for the application of realistic lightning impacts.
We conduct the following tests:
Buildings, wind turbines and other tall installations are exposed to lightning strikes. Therefore, lightning risk analysis and lightning risk management are key factors in ensuring the safe and reliable operation of these and all mission critical installations. In close collaboration with you, we perform lightning risk assessments on different levels and define the risk management strategy.
The lightning risk analysis includes:
The risk of being struck by lightning is the first thing to consider by exploiting numerical tools (FEM) along with strike density data from lightning location networks. Such analysis can be conducted on entire wind farms or other large installations to identify areas exposed to direct strikes of different amplitudes.
We can arrange and tailor training sessions to your specific needs.
GLPS is performing annual or biannual lightning protection inspections on wind turbines and other complex structures in accordance with IEC 61400-24 and/or IEC 62305-1
Based on an agreed inspection protocol - either developed by GLPS or the Owner, the inspection is performed by visual inspection and resistance measurements.
During the inspection all parts of the lightning protection system is inspected. In case of wear and tear the worn components are replaced. In case of larger issues, this will be reported and the mitigation scheduled.
After any inspection GLPS is submitting a Technical Inspection Report.
The various services can be acquired as individual assignments or as parts of a larger project focusing on tailoring the best lightning protection solution possible.
We have experience in project partnership and can either participate with engineering resources or perform the project management including customer resources. In case of specific assignments, we can take turnkey responsibility for a lightning protection project including installation and documentation.
