Eaton Expands LED range for Efficient Lighting in Industrial Buildings Linergy LED
Eaton Expands LED range for Efficient Lighting in Industrial Buildings
DONCASTER … Power management company Eaton is aiming to improve the quality and efficiency of lighting in industrial buildings by expanding its range of robust LED luminaires. The new additions to Eaton’s comprehensive lighting portfolio are the Tufflite and Linergy LED luminaires. Additionally, its existing Litex family of products has been updated with the addition of next-generation LED technology.
Andy Gallacher, lighting product manager at Eaton, said: “There is huge potential for industrial buildings to increase energy efficiency by switching from older fluorescent or high intensity discharge luminaires to the latest LED technology. This can not only reduce running costs but also saves on maintenance due to its longer lifespan. In warehouses, for example, lighting can account for up to 70 per cent of energy usage, while the figure is around 35 per cent for manufacturing sites. However, while the potential savings are significant, there’s also an urgent need to improve the quality of lighting in many industrial buildings, which have traditionally suffered from poor performance in this regard. Better lighting can have a major impact on the general wellbeing, productivity and safety of building occupants. Eaton’s latest Linergy, Tufflite and Litex LED luminaires have been purpose-designed to help those responsible for industrial buildings meet these objectives.”
Linergy LED follows in the tradition of Eaton’s highly efficient large-space luminaires which have the performance and flexibility for today’s multi-use and multi-occupancy locations. Incorporating the latest LED light engine technology, the luminaire delivers high lumen outputs and class-leading efficacies of up to 115 lumens per circuit watt (Llm/cW). When combined with the integral occupancy and daylight sensors, this can offer substantial energy savings for the end user.
The versatile Tufflite LED luminaires, with IP66 rated ingress protection, are suitable for areas where protection of the luminaire from environmental effects is vital. Offering a comprehensive range of lumen outputs across three lengths, the versatile LEDs are ideal for new and retrofit applications in warehouses, car parks, assembly areas and loading and storage spaces.
Additionally, Eaton has added new-generation LED options to its Litex range to improve the luminaires’ versatility and performance in industrial and warehouse environments. The enhanced Litex LEDs offer a 15 per cent rise in lumen (lm) output and are available with a choice of lumen packages controlled by open area, rack aisle or narrow distribution reflector options. Additionally, the new luminaires are designed to accommodate different mounting heights and installation methods, resulting in a solution that can be tailored to diverse applications.

Safety Above The Standard
Safety Above The Standard
We must do more to guard against electrical safety risks
For power-critical commercial buildings such as process plants, industrial infrastructure, data centres as well as for hospitals, airports and tunnels a continuous supply of electrical power is essential. The provision of reliable power in such buildings is reliant upon the low-voltage distribution panels that lie at the heart of the electrical installation. The demands placed upon these panels, particularly as operations and infrastructure expand over time, leaves them intensely vulnerable to arc faults. In this article, Bernhard Gegenbauer, power distribution product manager at Eaton, explores the consequences of arc faults and questions whether organisations are doing all they can to minimise the risk.
An arc fault in an electrical distribution panel is difficult to ignore. A massive build-up of pressure within the panel, rising to 25 tonnes per square metre, leads to what can only be described as an explosion, sending components flying through the air, destroying the installation and threatening the life of anyone nearby. If that initial blast is not damaging enough, the aftermath brings further risks, with the prospect of lengthy downtime.
New research commissioned by Eaton estimates that, for a typical food industry plant, the cost of production downtime alone could escalate to €40,000 in 24 hours. Then there is the cost of replacement switchgear, potential legal action and reputational damage on top of that. In short, people, property and business continuity are all put at serious risk both in the immediate timeframe and the longer term.
Despite these palpable dangers, electrical distribution panels are easy to overlook in a safety analysis of commercial building infrastructure. The equipment is generally tucked out of sight and the prevailing view is that switchgear is absolutely safe as long as it conforms with the requirements of the (International Electrotechnical Commission’s) IEC/EN 61439 standard.
However, research by Eaton suggests that compliance with the standard may not be sufficient to maximise protection. Eaton suggests that a higher level of safety can be achieved with the implementation of new technologies. As a result, it’s possible to further reduce the risk of a catastrophic arc fault and its costly aftermath.
Low-voltage electrical distribution panels are the beating heart in the supply of electrical power. Building owners and managers have a legal obligation to ensure that the switchgear assembly that drives processes meets the requirements set by the IEC, the international standards and conformity assessment body for all fields of electrotechnology. Business must ensure by law that equipment is planned, built and tested to the relevant version of the IEC/EN 61439 as well as other relevant standards.
In a whitepaper commissioned by Eaton, Safety and Risk in Electrical Low-voltage Installations, electrotechnical safety expert Alfred Mörx, explains “the purpose of the planning and execution of low-voltage installations is to achieve safety while excluding risks”.
What this means is that building owners and managers must ensure that any risk that remains after protective measures have been put in place must be as low as possible and does not exceed “the highest acceptable risk”.
However, even businesses that meet their legal duties are not immune from the risk of arc faults. Over time, energy intensive companies may expand operations, adding new installations on to existing systems. The end result is that the risk of an arc fault occurring increases., not only destroying valuable property and assets, including the installation, but also severely disrupting business continuity and potentially endangering lives.
Arc faults can also be triggered during maintenance or expansion projects when by accident conductive parts drop on the busbars while working on the panel. This is a life threatening scenario for any personnel in the vicinity of the incident. However, it is also possible for a devastating arc fault to be triggered by something as simple as a small animal crawling into the panel, and there are documented cases to prove it.
Partial or complete destruction to the power distribution system will inevitably lead to business interruptions, which can last days, weeks or even months. The key point to make is that the consequential damages (the costs that arise during business interruptions) increase significantly the longer the interruption.
Commercial buildings with critical power needs are especially vulnerable to power failures. System reliability and continuity of power supply are vital. After all, the sudden loss of power midway through an industrial process could mean that valuable resources and products can no longer be used. It wouldn’t take long for the cost of the original fault to mount significantly, and there could be environmental outcomes too if hazardous substances or materials need urgent disposal.
The whitepaper provides a detailed economic assessment of the total costs that businesses can face in the event of an arc flash incident, represented in an estimated costing per hour of downtime for typical applications. The total consequential damages for a 24-hour period, including loss of profits, cleaning and restart costs and additional costs such as penalties for failing to keep delivery dates, could amount to €40,000.
The calculation is based on an average production or filling facility in the food industry, and shows how the costs rise exponentially hour by hour.
It’s also worth bearing in mind that the typical replacement cost for a panel quickly reaches the few hundred thousand Euro mark, while sourcing and installing replacement parts can easily take a few days up to weeks. During that time, the facility is effectively out of action.
While businesses need only meet the minimum requirements set out in IEC 61439, Article 6 (2) of the EU Directive 89/391/EEC stresses that employers should consider ‘state of the art’ technology to create safe working conditions. According to Mörx, ‘state of the art’ technology such as arc fault protection is a key measure that employers can take to reduce possible consequential damages and enhance employee protection while also going beyond the minimum requirements.
According to Mörx: “Switchgear assemblies that only fulfil the minimum requirements are very likely to fall below the highest acceptable risk in the direction of hazard when an event occurs. If additional action is taken, the extend of damage in the installations and/or business interruptions with considerable consequential damages can be reduced. The same applies to any health impairments of employees that work in or near plants. The low-voltage switchgear assemblies equipped with additional measures have some kind of ‘safety reserve’.”
To maximise safety, two of the most effective strategies are firstly to monitor for unusual temperature rises that could indicate an imminent fault and secondly to ensure that, in the event of an arc fault, the event is identified in real-time in order to rapidly shut down the switchgear and minimise damage to the panel itself and also any connected equipment.
In temperature monitoring, the traditional use of thermal imaging provides a limited snapshot that doesn’t necessarily cover all of the main areas of the panel, including in some cases the crucial bus bars. However, new technology from Eaton continuously monitors temperature trends at critical points and sends data wirelessly to a separate controller, enabling engineers to analyse heat levels of a selected period of time and conduct further investigations or preventative maintenance work accordingly.
Eaton’s long-established expertise in switchgear safety is further demonstrated by its Arcon arc fault protection system, which shuts down the panel within a market-leading time of two milliseconds in order to minimise damage. By reacting significantly faster than the widely-accepted timeframe of 20 to 50 milliseconds, the system limits the level of damage.
In order to ascertain the level of risk and respond accordingly, Eaton recommends that relevant stakeholders in power-critical commercial buildings ask themselves a series of searching questions:
• What are the technical impacts of a failure to the switchgear assembly?
• How high are the consequential damages?
• What are the possible effects of a failure of the switchgear aseembly on the employees ensuring servicing?
• How heavy is the damage to the company’s image because delivery times cannot be kept?
• What are the impacts of a failure of a switchgear assembly on the environment?

Eaton has helped enhance electrical reliability, safety and personnel protection at Airbus’ largest production facility in Germany by upgrading a part of its low-voltage power distribution unit to state-of-the-art standards. The power management company was called upon to provide a complete solution including switchgear monitoring, continuous temperature monitoring at critical points within the cabinets as well as an arc fault protection system.
The installation, in hall nine of Airbus’ Hamburg-Finkenwerder site, provides the company’s maintenance and energy team with unprecedented insight into the performance of the low-voltage power distribution system so that potential problems such as over-current, under-voltage, overload or arc faults can be quickly detected, viewed and corrected. This helps to ensure the maximum reliability of the power supply, as well as protecting employees from any incidence of arc fault.
The site, which specialises in the final assembly of the A320 programme, is operational 24/7 and depends upon maximum technical system reliability.
Eaton’s diagnostic system for temperature monitoring allows the temperature of critical areas of the switchgear to be monitored continuously for the first time. The system is based on a diagnostic controller and autonomous temperature sensors for monitoring all bus bars and connection points, as well as versatile temperature sensors for all other measurement points. As part of the project, almost 80 temperature sensors were installed in the switchgear for hall 9. In the event of deviations, the system either generates a warning about the present error or triggers an alarm if certain thresholds are exceeded.
In order to enhance the main distribution unit in terms of personnel safety, Eaton’s Arcon arc fault protection system was also fitted.
