论文摘要
树木表法和三个电压表法用于测量功率。更具体地说，它们用于计算特定负载的功率因数。两种方法均用于萨格勒布应用科学大学电气工程专业研究的电气工程课程的基础知识，以介绍功率和相法算术的测量。两种方法都容易受到测量设备中较小错误引起的准确性问题。在课程中使用的特定情况下，这些准确性问题为学生提供了有关理论及其实际应用的机会。本文研究了我们解决的精度问题的解决方案，并讨论了课程材料和教学方法中所做的变化，以突出理论与实践之间的区别。
The tree ammeter method and the three voltmeter method are used for measurements of power. More specifically, they are used to calculate the power factor of a specific load. Both methods are used on the Fundamentals of electrical engineering course in professional study of electrical engineering at the Zagreb University of Applied Sciences as an introduction to measurements of power and phasor arithmetic. Both methods are susceptible to accuracy problems caused by small errors in measuring devices. These accuracy problems in specific scenarios that were used during the course presented an opportunity to educate students on the difference of theory and its practical application. This paper examines our solution to the perceived accuracy problems and discusses the changes that were made in course material and teaching methods to highlight the difference between theory and practice.
