Basic Categories of Energy Meters There are many basic types of Energy Meters that it is not an easy task to categorize them. Still I will try my best to sort out different types of energy meters in some simple manner. First, look at this hierarchy chart, it will give a brief idea about the […]

## Objectives of Energy Meters

Objectives of Energy Meters With the advancement of technology, objectives of energy meters are not merely to measure energy units. Objectives went far behind from just giving energy readings of some specific consumer. Also, these objectives are not constant, they are increasing day by day with the increase in advancement in energy sector. Let’s discuss […]

## Basics of Energy Meters

What is Energy Meter? A device which captures the “units of energy” is called as Energy Meter. This is the basic definition of an Energy Meters. The only difficult part in this definition is “units of energy”. Let’s describe this part in more detail. What are Units of Energy? To understand about the units of […]

## Transformer Design Turns per Volts

Transformer Design Turns per Volts In previous article, we derived a formula for turns per volts of transformer winding for transformer design. That formula has core area involved in it. Now, we are going to derive a formula for transformer design turns per volts according to transformer ratings and depending upon type of transformer and […]

## Optical Mark Recognition using MATLAB

Optical Marking Recognition (OMR) Optical Marking Recognition using MATLAB Software is for marking tests or extract data from documents such as survey. This software obtained marked data from specific sheet designed for this, called as OMR sheet. Basically, this recognition software falls in category of image processing. We are going to write our own code […]

## Turns per Volts Derivation Transformer Design

Derivation of Formula for Calculation of Turns per Volts of Transformer Design For designing a transformer, we need certain number of turns on each side for a specific rating transformer. Voltages on each side have direct relation with number of turns. So, we are interested in finding voltage per turn and for designing, turns per voltage. […]
