The Accuracy Comparison of Oscilloscope and Voltmeter Utilizated in Getting Dielectric Constant Values
Proceeding The 1st IBSC: Towards The Extended Use Of Basic Science For Enhancing Health, Environment, Energy And Biotechnology 211 ISBN: 978-602-60569-5-5 The Accuracy Comparison of Oscilloscope and Voltmeter Utilizated in Getting Dielectric Constant Values Bowo Eko Cahyono1, Misto1, Rofiatun1 1 Physics Departement of MIPA Faculty, Jember University, Jember – Indonesia, e-mail: [email protected] Abstract— Parallel plate capacitor is widely used as a sensor for many purposes. Researches which have used parallel plate capacitor were investigation of dielectric properties of soil in various temperature [1], characterization if cement’s dielectric [2], and measuring the dielectric constant of material in various thickness [3]. In the investigation the changing of dielectric constant, indirect method can be applied to get the dielectric constant number by measuring the voltage of input and output of the utilized circuit [4]. Oscilloscope is able to measure the voltage value although the common tool for that measurement is voltmeter. This research aims to investigate the accuracy of voltage measurement by using oscilloscope and voltmeter which leads to the accuracy of values of dielectric constant. The experiment is carried out by an electric circuit consisting of ceramic capacitor and sensor of parallel plate capacitor, function generator as a current source, oscilloscope, and voltmeters. Sensor of parallel plate capacitor is filled up with cooking oil in various concentrations, and the output voltage of the circuit is measured by using oscilloscope and also voltmeter as well. The resulted voltage values are then applied to the equation to get dielectric constant values. Finally the plot is made for dielectric constant values along the changing of cooking oil concentration. -
A Rapid Inductance Estimation Technique by Frequency Manipulation
Latest Trends in Circuits, Control and Signal Processing A Rapid Inductance Estimation Technique By Frequency Manipulation LUM KIN YUN, TAN TIAN SWEE Medical Implant Technology Group, Materials and Manufacturing Research Alliance, Faculty of Biosciences and Medical Engineering, Universiti Teknologi Malaysia, Skudai 81310, Johor, Malaysia [email protected]; [email protected] Abstract:- Inductors or coils are one of the basic electronics elements. Measurement of the inductance values does play an important role in circuit designing and evaluation process. However, the inductance cannot be measured easily like resistor or capacitor. Thus, here would like to introduce an inductance estimation technique which can estimate the inductance value in a short time interval. No complex and expensive equipment are involved throughout the measurement. Instead, it just required the oscilloscope and function generator that is commonly available in most electronic laboratory. The governed theory and methods are being stated. The limitation of the method is being discussed alongside with the principles and computer simulation. From the experiment, the error in measurement is within 10%. This method does provide promising result given the series resistance of the inductor is small and being measured using proper frequency. Key-Words: -Inductor, Inductance measurement, phasor, series resistance, phase difference, impedance. • Current and voltage method which is based on the determination of impedance. 1 Introduction • Bridge and differential method which is based on the relativity of the voltages and There are many inductors being used in electronics currents between the measured and reference circuits.

They are typically mounted in cases that are 10 to 20 cm on a I. Introduction side with large connectors, and are not easily incorporated into a programmableimpedance standard. To overcome this problem, chip Commercial digital impedance meters, often referred to as LCR components were evaluated as possible impedance standards and it meters, are used much like digital multimeters (DMMs) as diagnostic was discovered that some of these chips are approaching the quality and quality control tools in engineering and manufacturing. Like the of the older laboratory standards. For example, I of ceramic chip best DMMs, the accuracies of the best LCR meters are approaching capacitors are available with temperature coefficients of 30 ppml°C those of the standards that support them. The standards are 2- to 4- compared to 5 ppml°C for gas capacitors. -
Part 2 - Condenser Testers and Testing Correctly Part1 Condenser Testers and Testing Correctly.Doc Rev
Part 2 - Condenser Testers and Testing Correctly Part1_Condenser_Testers_And_Testing_Correctly.doc Rev. 2.0 W. Mohat 16/04/2020 By: Bill Mohat / AOMCI Western Reserve Chapter If you have read Part 1 of this Technical Series on Condensers, you will know that the overwhelming majority of your condenser failures are due to breakdown of the insulating plastic film insulating layers inside the condenser. This allows the high voltages created by the “arcing” across your breaker points to jump through holes in the insulating film, causing your ignition system to short out. These failures, unfortunately, only happen at high voltages (often 200 to 500Volts AC)….which means that the majority of “capacitor testers" and "capacitor test techniques" will NOT find this failure mode, which is the MAJORITY of the condenser failure you are likely to encounter. Bottom line is, to test a condenser COMPLETELY, you must test it in three stages: 1) Check with a ohmmeter, or a capacitance meter, to see if the condenser is shorted or not. 2) Assuming your condenser is not shorted, use a capacitance meter to make sure it has the expected VALUE of capacitance that your motor needs. 3) Assuming you pass these first two step2, you then need to test your condenser on piece of test equipment that SPECIFICALLY tests for insulation breakdown under high voltages. (As mentioned earlier, you ohmmeter and capacitance meter only put about one volt across a capacitor when testing it. You need to put perhaps 300 or 400 times that amount of voltage across the condenser, to see if it’s insulation has failed, allowing electricity to “arc across" between the metal plates when under high voltage stress. -
Lab 5 AC Concepts and Measurements II: Capacitors and RC Time-Constant
Sonoma State University Department of Engineering Science Fall 2017 EE110 Laboratory Introduction to Engineering & Laboratory Experience Lab 5 AC Concepts and Measurements II: Capacitors and RC Time-Constant Capacitors Capacitors are devices that can store electric charge similar to a battery (but with major differences). In its simplest form we can think of a capacitor to consist of two metallic plates separated by air or some other insulating material. The capacitance of a capacitor is referred to by C (in units of Farad, F) and indicates the ratio of electric charge Q accumulated on its plates to the voltage V across it (C = Q/V). The unit of electric charge is Coulomb. Therefore: 1 F = 1 Coulomb/1 Volt). Farad is a huge unit and the capacitance of capacitors is usually described in small fractions of a Farad. The capacitance itself is strictly a function of the geometry of the device and the type of insulating material that fills the gap between its plates. For a parallel plate capacitor, with the plate area of A and plate separation of d, C = (ε A)/d, where ε is the permittivity of the material in the gap. The formula is more complicated for cylindrical and other geometries. However, it is clear that the capacitance is large when the area of the plates are large and they are closely spaced. In order to create a large capacitance, we can increase the surface area of the plates by rolling them into cylindrical layers as shown in the diagram above. Note that if the space between plates is filled with air, then C = (ε0 A)/d, where ε0 is the permittivity of free space. -

Capacitance and Dissipation Factor Measurementst from 1 kHz to 10 MHz " Presenter: A. D. Koffman NIST, 220/B162, Gaithersburg, MD 20899 (301) 975-4518 Paper Authors A. D. Koffman, B. C. Waltrip, N. M. Oldham National Institute of Standards and TechnologY: Gaithersburg, MD S. Avramov-Zamurovic U.S. Naval Academy Annapolis, MD Abstract: A measurement technique developed by K. Yokoi et al. at Hewlett-Packard Japan, Ltd. has been duplicated and evaluated at the National Institute of Standards and Technology (NIST) to characterize four-tenninal pair capacitors. The technique is based on an accurate three-terminal measurement made at 1 kHz using a capacitance bridge and wideband single-port measurementsmadebetween30MHzand200 MHz usinga networkanalyzer. The measurement data are fitted to the four-tenninal pair admittance model defmed by R. Cutkosky to compute capacitance and dissipation factor at any frequency up to 10 MHz. Capacitors characterized using this technique will be used as impedance reference standards for a general- purpose digital impedance bridge recently developed at NIST to calibrate inductors and ac resistors. The technique could also lead to a future NIST Special Test for dissipation factor. INTRODUCTION Recent efforts by the Electricity Division at the National Institute of Standards and Technology (NIST) to develop improved impedance comparison methods from 20 Hz to 1 MHz (1)have made it necessary to fmd a means to evaluate the reference impedances used in such comparisons. The impedance-characterization method discussed in this paper is described by Suzuki, et al. (2)and is based on the four-tenninal pair impedance work of Cutkosky (3)and Jones (4,5) The four-terminal pair impedance, Z4tp'of a device is defined as a combination of its real component, R, and its imaginary component, X: Z41p= R+ jX. -

EE 462G Laboratory #1 Measuring Capacitance Drs. A.V. Radun and K.D. Donohue (1/24/07) Revised by Samaneh Esfandiarpour and Dr. David Chen (9/17/2019) Department of Electrical and Computer Engineering University of Kentucky Lexington, KY 40506 I. Instructional Objectives Introduce lab instrumentation with linear circuit elements Introduce lab report format Develop and analyze measurement procedures based on two theoretical models Introduce automated lab measurement and data analysis II. Background A circuit design requires a capacitor. The value of an available capacitor cannot be determined from its markings, so the value must be measured; however a capacitance meter is not available. The only available resources are different valued resistors, a variable frequency signal generator, a digital multi-meter (DMM), and an oscilloscope. Two possible ways of measuring the capacitor’s value are described in the following paragraphs. For this experiment, the student needs to select resistors and frequencies that are convenient and feasible for the required measurements and instrumentation. Be sure to use the digital multi-meter (DMM) to measure and record the actual resistance values used in each measurement procedure. III. Pre-Laboratory Exercise Step Response Model 1. For a series circuit consisting of a voltage source v(t), resistor R, and capacitor C, derive (show all steps) the complete solution for the capacitor voltage vc(t) when the source is a step with amplitude A and the initial capacitor voltage is 0. 2. Assume the source v(t) is a function generator, where the source voltage can only be measured after the 50 Ω internal resistance. -
