Abstract

Summary form only given. This paper has two sections. In the first section, a description of many details, and of many small but important items, introduced in the electronic circuitry of power and energy meters, is given. Also, the explanation is presented of how the reduction is achieved to voltage and current. The second sections deals with power and energy calibrators and with very accurate instruments built for national and other high precision measurement laboratories. The first section deals primarily with the analog electronic circuitry and the description of the systematic and other error origins. The second section describes the implementation of the digital circuitry and digital computation in the calibration of high precision instruments. As everyone is aware, the calibrators are instruments in which the control problems are essential. In this paper, the author explains his recent views regarding the feedback, error feedforward and error feedback methods, and compares the analog and digital approaches in the realization of these control strategies.<>
电能表及其校准
只提供摘要形式。本文分为两部分。在第一节中,对电能表电子电路中的许多细节和许多小而重要的项目进行了描述。此外,还解释了如何实现电压和电流的降低。第二部分涉及电力和能源校准器以及为国家和其他高精度测量实验室建造的非常精确的仪器。第一部分主要讨论模拟电子电路以及系统误差和其他误差来源的描述。第二部分介绍了数字电路和数字计算在高精度仪器标定中的实现。大家都知道,校准器是控制问题至关重要的仪器。本文阐述了他最近对反馈、误差前馈和误差反馈方法的看法,并比较了实现这些控制策略的模拟和数字方法。
