一家造纸和纸浆公司。
挑战
造纸和纸浆行业正在将智能高科技机器与高效生产线连接起来。更高功率的直流和交流电机驱动器执行自动化任务。每一种对安装的可靠性和安全性产生负面影响的干扰都可能导致生产停机，从而导致重大的经济损失。交流和直流电机驱动器是所谓的非线性负载，因为它们从电网汲取非正弦电流。由此产生的电流和电压谐波会干扰附近用户的运行并使电力基础设施过载。在此特定应用中，驱动器的负载循环通常会由于干扰耦合到现场总线系统中而导致生产过程中断。
解决方案
夏弗纳总补偿电流为 150A 的有源谐波滤波器解决了这些特殊问题。为了确保最大可用性，三个 FN 3420-50-480-3 滤波器并联安装，并与 480/525V 匹配变压器一起运行。滤波器的增量连接导致与电能质量相关的中断明显且可验证地减少。对整个装置的这个相对较小部分的补偿已经导致电压失真 THVD 降低了 1.3 个百分点。

Case Study
Wireless Improves Efficiency in Compressed Air Systems
Hollingsworth and Vose wanted to improve the efficiency of their compressed air system, lower the electricity expense component of manufacturing cost in their commodity industry, and conserve energy leading to lowered greenhouse gas emissions. Compressed air systems degrade over time and become leaky and inefficient. Hollingsworth and Vose wanted to increase the frequency of system inspections without paying the high cost of manual labor.

Process Predictive Analysis in Pulp and Paper Mill
Common paper breaks consequently lead up to 60 minutes of downtime, delaying a potential $10K per hour of production value process. Thus, defective products cause financial and damage company's reputation. Improving quality and reducing defect rates can generate millions of dollars of revenue per year for your company.
Case Study
Industrial Video Monitoring for Security and Regulatory Compliance
Because of the Stevenson mill’s proximity to the Tennessee River, WestRock was required by the USCG to comply with the Maritime Security 33CFR (MARSEC) regulations. WestRock needed a video security system but wanted to add other applications not required by the government, such as video process monitoring, condition monitoring, and wireless network management. WestRock needed a reliable video solution to avoid the compliance fines and possible security risks – but the solution needed to be implemented in the most cost-effective manner possible.

Covantis Case Study: Modernizing Global Supply Chains with ConsenSys Blockchain Solutions
The global agricultural trade industry has been grappling with outdated and inefficient processes. The industry has not seen significant technological innovation since the mass adoption of email 30 years ago, making global supply chain management increasingly challenging. The need to track more partners, suppliers, and endpoints has become more complex, and post-trade execution remains highly manual, repetitive, costly, and time-consuming. The industry is heavily reliant on paper-based processes and email exchanges, with over 275 million emails exchanged annually to process an estimated 11,000 worldwide shipments of grain. Paper-based certificates and bills of lading are not easily exchanged among multiple parties, and replacing them if misplaced is costly. The COVID-19 pandemic has further disrupted supply chains due to interruptions to paper document deliveries and the increasing necessity to work from home, accelerating the need for digital transformation.
