According to the Carbon Trust, cash savings of up to 20 per cent can be achieved through energy efficiency measures such as installing variable-speed drives (VSD) for fans, pumps, and other motor driven systems. But, a one size fits all approach to energy savings just won’t do. Here, John Mitchell, global sales & marketing director at supply, installation and repair specialist CP Automation, explains how plants should measure their energy usage to find the best energy saving opportunities.

The ISO 50001 standard requires organisations to establish, implement, maintain and improve an energy management system. To make energy savings, a plant manager must first understand their facility’s energy usage. It sounds obvious, but in reality, achieving energy control and crucial ongoing energy savings requires a strategized approach. The first step is to measure your energy usage.

Many modern distribution and energy management systems already incorporate energy monitoring and logging facilities. However, they may only have a limited amount of memory and are unable to store results over an extended period. In addition, many integrated monitors only store summarised data that do not provide the level of detail needed for effective energy optimisation.

Portable power and energy loggers (PELs) provide a convenient and cost-effective alternative, with far superior capabilities. These PELs, from Chauvin Arnoux for example, can be installed in several different locations, with data from different processes or equipment available on a single screen. A real benefit of these modern devices is that equipment doesn’t need to be turned off and isolated during the installation process.

The next step is carrying out an energy audit. The data from the PEL will show where the most energy is being used in your plant and consequently where the most potential for energy savings can be found. The results from this report will inform the type of improvements to implement and crucially where they should be implemented.

Energy saving opportunities can fall into two broad categories, those that relate to the workplace environment and technical aspects of the electricity supply. For example, a plant could improve the efficiency of the workplace environment by cutting down on unnecessary out-of-hours usage by switching to LED lighting with occupancy sensors. On the other hand, an energy audit may find that a motor is consuming a high amount of wattless or useless power. In this instance, power factor correction would need to be installed to reduce this wastage, without compromising the performance of the equipment.

It’s one thing implementing energy savings, but it’s also important to continually monitor your system to ensure you’re getting ongoing energy improvements. Plants should also formulate a metering plan to measure and analyse energy usage over an extended period of time. This will assess whether the chosen energy efficiency measures have been effective or whether further improvements can be made.

Plants may choose to implement energy efficiency schemes for a range of reasons. While there are several universal energy saving fixes, it’s important that facilities use a targeted approach, which accurately monitors their systems to achieve the most effective energy and cost saving potential.

All Happening Live: the Eplan Virtual Fair

Rittal and EplanLast year Eplan welcomed around 1,400 attendees from 73 countries to its international Virtual Fair. Impressive figures – and that in times before such virtual formats had become the standard almost everywhere. This year the interest in new, innovative Leadership Talks, practice-oriented webcasts and worldwide chats for talking shop with other users is likely to increase again.

This year’s Eplan Virtual Fair has a full sixteen-hour programme planned. This year marks the fifth edition of the global “trade show on the net”, which has enjoyed a continually growing number of visitors from all around the world. The fair will be broadcasting, presenting and chatting live from 6.00 am to 10.00 pm (CEST).

Safety Scanner or Safety Mat? How to Choose the Right Safeguarding Device.

 

Omron Safety ScannerYou've done your risk assessment, and now it's time to implement a risk reduction strategy using engineering control measures. Since physical barriers can be costly and impractical, many manufacturers opt for what are known as presence sensing devices, a category that includes technologies like safety light curtains, safety laser scanners, and safety mats.

Because they don’t physically prevent an operator from reaching the hazard zone, presence sensing devices only work for machines that can be stopped anywhere in their cycle. Each device must be positioned far enough away from the machine that it’s extremely unlikely for anyone to be able to reach the danger area after triggering the safety response.

Pandemic Creates New Job Roles and Fosters Automation Investment

Pandemic Job RolesBy Pat McGibbon, Chief Knowledge Officer, AMT

Those who cannot remember the past are condemned to repeat it.” This observation was made by philosopher George Santayana in 1905, but can help manufacturers today avoid mistakes in responding to the impacts of the pandemic. History shows that there are two likely outcomes of the current crisis which relate to manufacturing.

First, automation and digital manufacturing technologies will expand sooner and faster than the manufacturing technology market as a whole over the next two years. Second, this growth spurt will lead to changes in the manufacturing workforce throughout the recovery.

Albesol Looks to Build off Schneider Electric Premset Medium Voltage Switchgear Partnership in Canada

 

AlbesolBy Sarah Pickard

As a Premset Medium Voltage Switchgear and modular system electrical cabinets manufacturer and service provider, Albesol INC is the first licensed partner on the Premset offer for Schneider Electric in Canada. Albesol’s Canadian operations were founded in 2018 when the company expanded its operations from Albania, where they worked primarily in the energy and power sector.

The Canadian arm of the company is centered around Premset Switchgear, which is applicable across a number of industry segments: mining, data centres, commercial, industrial and institutional buildings, as well as portable substations.

Condition Monitoring Sensor With Integrated Data Preprocessing

Condition Monitoring SensorUnscheduled stops and faults in the production process can be avoided using our new multi-functional condition monitoring sensor. This intelligent sensor provides you with condition information which you can use for automating costintensive manual inspections. This condition data is also an essential component for implementing smart and flexible manufacturing – a key to IIoT.
