“…Accurate measurement of the PF for electrical energy is becoming a developing topic among researchers since it distributes electrical energy at an acceptable cost. The cost of electrical energy rises as a result of power losses in transformers, transmission lines, and loads [1,2]. Due to its versatile features and rich library functionalities, the Arduino is gaining traction in this field (i.e., measurement devices and monitoring systems).…”

The power factor (PF) is an important measurement in an AC electrical system that indicates how much power ‎is utilized to accomplish productive work by a load and how much power is consumed. As a result, it's one of ‎the primary causes of excessive energy costs and power outages. This paper aims to present a simple, cost-‎effective, and accurate PF metering and monitoring system implemented using an Arduino microcontroller with ‎a novel methodology different from other papers. The proposed method is to design the software code instead ‎of using external components of Zero-Crossing Detectors (Z-CDs) for both voltage (V) and current (I) signals, and ‎instead of using Exclusive-OR (X-OR) gates also. Determining the phase-angle and PF in an efficient manner ‎can be useful in many approaches to electrical systems: 1-for synchronization of parallel connections of ‎alternators; 2-for directional protection systems; 3-for PF correction and load management; and 4-for designing ‎watt/energy meters. Using the Proteus 8 Professional (ISIS program), the proposed designed circuit was ‎simulated for more verification. The simulation and experimental findings are presented to validate the ‎proposed metering system's effectiveness.‎

This paper depicts a remote vision-based manual motion control of five degrees of freedom (DoF) articulated industrial robotic arm intended for teleoperation. Remotely operated robot arms are now involved in handling heavy loads, detrimental materials or to explore uninhabitable spaces. In this light, a robotic system is developed in this paper to administrate this manipulation tasks from a distance in order to improve job safety and to alleviate the function of professionals. The proposed system carries a modular mechanical design for simplifying the function and maximizing the performance of the robot arm. The kinematic design of the 5 DOF robotic arm is carried out first to develop a sophisticated model that reflects the motion in the real world. The verification of the kinematic model is performed by observing the output response obtained from the simulation study. The robotic system considered in this study is a fixed base robotic system where the position of the robotic manipulator is determined by the operator. Before conveying the developed system to the real world, the computer-aided design is accomplished. Thereafter, the Live camera feeds are taken by a wide-angle camera, and the data bits are transmitted to a base station. A human operator then manipulates the robot arm using a controller according to the received camera feeds. An IEEE 802.11 standard communication technique is adopted to establish a three-way communication path. The paper presents the mechanical design along with the kinematic analysis, simulation studies and its application to real world explicates the comprehensive control over its performance.

Upper harmonics that occur in electrical installations due to the use of semiconductor components increases the angle of phase difference between the voltage and the current of a phase. Following this, the power factor decreases, which necessitate, then, installations to compensate for it - to reduce or cancel the upper harmonics. In this work we present a case study on how upper harmonics influence the power factor. This work has been supported by Project CNFIS-FDI-2018-0282.
