ELECTROMAGNETIC RADIATION

Electromagnetic radiation is any form of energy-carrying radiation created by the interaction of electric and magnetic fields. It comes in many different types, although the differences between them are quantitative rather than qualitative. This book lists the different types that are generally recognised. Electromagnetic radiation is a wave, so has a wavelength λ and a frequency ν. It is also composed of particles called photons, and each photon has an energy E. These three quantities are related, and any of them may be used to define the type of radiation. The properties of electromagnetic radiation were first investigated by James Clerk Maxwell in 1864. He realised that in a vacuum they would travel at the speed of light, and he correctly deduced that light is radiation of this form.

Voltage and Current Profile

Voltage and Current Profile Improvement of a PV-integrated Grid system employing Sinusoidal Current Control Strategy based Unified Power Quality Conditioner Abstract- The basic aim of the electric power sector is to produce power as when required at the suitable sites, then transmitting and distributing to various load centres retaining the quality and fidelity of supply with economical tariff. This paper focuses on mitigation of power quality (PQ) issues in a PV-integrated grid system by implementing constant Sinusoidal current control strategy (SCCS) based simulation of UPQC (Unified Power Quality Conditioner) using MATLAB R2016a in association with various loads.

DIGITAL VOLTMETER

What is a digital voltmeter? A voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit; digital voltmeters give a numerical display of voltage by use of an analog-to-digital converter

MEASUREMENT OF NON ELECTRICAL QUANTIES

Mostly quantities to be measured are non-electrical such as temperature, pressure, displacement, humidity, fluid flow, speed etc., but these quantities cannot be measured directly. ... The function of converting non-electrical quantity into electrical one is accomplished by a device called the electrical transducer.

TRANSDUCERS

A transducer is any device used to convert energy from one form to another - typically when converting input energy into output energy. For transduction to occur, a change from one form of energy must also take place, such as a conversion from mechanical to electrical energy or vice versa.
