自动电弧闪光能量评估
执行电弧闪光分析并自动评估多个位置的事件能量和电弧闪光损坏点。了解更多
该网络研讨会介绍了用于电弧闪光危险计算的欧洲/德国标准 DGUV-I 203-077。这种方法与 IEEE 1584-2018 一样,在许多欧洲国家都在使用。我们将德国电弧闪光方法与 IEEE 1584-2018 进行比较,并介绍基于此标准可用于电弧闪光计算的 ETAP 工具。将介绍应用示例以及特性和功能。了解更多
建议用于 15 kV 及以上电力系统的电弧闪光分析软件,符合 OSHA 对电力传输、配电、工业和可再生能源系统的要求。了解更多
ETAP 电弧闪光计算器提供了强大的图形工具,用于快速评估多个或批量的“假设”情景。无需构建单线图即可创建电弧闪光警告标签。
通过验证电弧闪光缓解技术来提高安全性并最大限度地减少设备损坏。 了解更多
在本视频中,我们演示了如何使用 ETAP 的雷电风险评估 (LRA) 模块来评估雷击风险和损坏的可能性。了解 ETAP 中使用的 LRA 计算方法以及如何执行 LRA 以符合国际标准 NFPA 780-2020、2014 和 IEC 62305-2:2010.探索雷电风险评估背后的重要原因。从雷电作为电涌的首要原因,到防止损害、火灾和其他对生命和财产的危害,考虑到不可预测的天气模式和资产保护,如建筑物、电力基础设施和人类生命,ETAP 的雷电风险评估模块将计算风险并提出防止对人类和基础设施造成伤害的步骤。

In most cases, SCCAF (Short Circuit Coordination Arc Flash) studies are done by engineering firms, which then submit reports to facility owners. The challenge is that those reports tend to be lengthy (up to 5,000 pages), not engaging, and hard to grasp for facility personnel. ETAP's powerful graphical and presentation tools can help make those reports livelier, informative, and more engaging. This case study will discuss how you can summarize lengthy power studies reports within just a 30-minute interactive meeting, and highlight how the final ETAP model can be used, with its powerful graphical interface and presentation tools, including Data Blocks, Multiple Presentation layers, Sequence of Operations, and Arc flash calculator.
Multiple arc flash incident energy mitigation methods are available, but how does an engineer know which is best for their client? This presentation identifies an approach to follow to pick the method, considering effectiveness, practicality, feasibility, and overall best option for realistic study results. With extensive experience with arc flash studies for many clients of all sizes, Mangan provides a real world demonstration of a project for a refinery client. The interplay between motor starting and arc flash analysis was evaluated, and mitigation recommendations were customized for the system. The challenges encountered during mitigation are identified, and the proposed solution is analyzed using ETAP Load Flow, Short Circuit, Arc Flash and Motor Acceleration Analysis. Safe motor operation, safe motor starting and arc flash protection are provided through customized mitigation methods and thoughtful system design.
