1 generating insight | edition 5 Foreword Welcome to the 5th edition of Generating Insight. Already three quarters of the way through 2014, the economic outlook looks extremely different than 12-18 months ago. While the economic environment has strengthened significantly over the past 12 months, demand is still highly variable in different markets, which presents us all with some ongoing challenges. It is therefore our duty to continue to develop world class solutions for our customers, improving our quality, cost-effectiveness, flexibility and responsiveness. Sharing the knowledge of our...

2 generating insight | edition 5 New Product Selector available on our website A new Product Selector tool to enable our alternators to be matched against customer power requirements has been developed and launched on the Cummins Generator Technologies website. During the introduction of the Product Selector we have updated our data to include STAMFORD P80 and AvK product information. The Product Selector will select an alternator based on the customer's power requirements and enable them to download the following material:■■ Product Guide – overview of product features and options ■■...

3 generating insight | edition 5 Cummins Receives Funding To Develop New Stop-Start Technology Cummins has been successful in its application for funding to support the development of new stop-start engine capabilities, improving commercial vehicle fuel efficiency and reducing CO² emissions. The UK’s innovation agency, the Technology Strategy Board is awarding £4.9 million of a total £9.9 million project to a Cummins led consortium to introduce this technology. The funding supports the Advanced Propulsion Centre’s initiative to build UK manufacturing strength in low carbon vehicles. Named...

4 generating insight | edition 5 Ian Melton, Castlet Managing Director commented “Castlet Ltd is delighted to be given the opportunity to work alongside Cummins on such an exciting new project and to be able to contribute towards the development of FIRST, which will make a huge difference to transport as we know it.” Prof. Neil Brown concluded “We are planning on developing an engine centric hybrid solution that is interchangeable with existing engine platforms at very low cost. The aim of project FIRST™ is to break down technology cost barriers by using a unique technical approach that...

5 generating insight | edition 5 Test Cell Upgrade At the Cummins Generator Technologies plant in Ryhall Road, Stamford the test facility has recently been upgraded from a no load production test cell to a full load test facility. It now has the capability to carry out full prototype testing on the STAMFORD P80 range of alternators, some P7 and up to the AvK DIG 142h/4 range which is produced in Craiova, Romania. The test cell was developed and built for production testing in 2008 and commissioned in 2009. When designing the test cell it was decided to “future proof” it, by putting in the...

6 generating insight | edition 5 The “back to back” method of loading involves mechanically and electrically coupling the load machine and test machines together and then load can be applied by rotating the stator of the load machine (independently of it’s rotor). By adjusting the excitation on the rotor of the load machine the power factor can be varied to obtain the rated power factor. Leading power factor can also be achieved. This circulating load test method, is very energy efficient with only the losses of the test machine, load machine and the prime mover having to be supplied. Phase...

7 generating insight | edition 5 Data Centre Power Requirements In today's culture, many of us carry electronic devices. Whether it is a smart phone, music player, tablet or laptop computer, at some point the device is connecting to the internet. There are applications on these devices that require data that is stored remotely, which means somewhere there is a data centre holding this data. These data centres have become commonplace, but are often invisible. Data centres can be in remote locations, such as the countryside of North Carolina; industrial parks in Hamburg; and even inside...

8 generating insight | edition 5 For example, the capacitive load of a server can push the operating limits of the alternator, so clear understanding of the load demands is required when selecting the alternator to be applied. Gen N Mech System Example of 2(N+1) redundant capacity with multiple power paths. Tier IV compliant. Facility loads for lighting, climate control, telecommunications, and security systems are more conventional, and often are supported through dedicated generator sets sized for purpose. Facility design may incorporate room for expansion, and space claim considerations...

9 generating insight | edition 5 UL Certification Underwriters Laboratories (UL) is an independent organisation that certifies, tests, inspects and audits for product compliance. UL is chiefly concerned with the safety aspects of products. Major Insulation includes materials that are relied upon to prevent a risk of electric shock or fire. These materials are used between the magnet wire and ground or between different phases of the windings. Manufacturers submit products to UL for testing and safety certification on a voluntary basis. There are no laws specifying that a UL mark must be...

10 generating insight | edition 5 The total time to complete a sealed tube test takes several months due to time taken for collecting samples from all plants. For alternators to be UL 1004 recognized the insulation system is required to be UL 1446 compliant. A product investigation by UL typically involves testing of product samples. Through the UL witness test data programme, performance tests are conducted at Cummins Generator Technologies test facilities under the supervision of UL personnel. A product technical file is established to include all the product construction features in...
