Principles of Electrical Measurement by S. Tumanski


 

PREFACE to Principles of Electrical Measurement by S. Tumanski:

In libraries and bookshops we are able to discover numerous books on electrical measurements1 . Most of them describe numerous elements of electrical measurements: digital or analogue strategies, sensors, information acquisition, information conversion, and many others.

Nevertheless, it may be tough to discover a guide that features a full information on the strategies utilized in taking electrical measurements.

The rationale for that is moderately apparent –trendy measuring requires data of many interdisciplinary matters akin to pc strategies, electronics, sign processing, micro- and nanotechnology, synthetic intelligence strategies, and many others. It’s virtually unattainable for one writer to know and clarify all these topics.

Due to this fact, there are continuously obtainable books referred to as “Handbook of…” written by dozens of co-authors. Sadly, such books are primarily extra conglomerates of many encyclopaedia entries of unequal ranges than complete and compact educated books.

The opposite facet of this drawback is that the progress in measuring strategies may be very quick, with yearly bringing new developments. It’s actually tough to catch the state of the artwork in measurements.

It’s a lot simpler to assemble data on a specific topic within the kind of a monograph centered on a particular drawback.

However then again, college students and trade engineers search for complete books which might be simple to grasp and most of all embrace current developments, such the pc measuring programs or digital measuring strategies.

I lecture on electrical measurements to college students of electrical engineering, robotics and informatics. To inform the reality I couldn’t discover a appropriate guide on the entire topic and subsequently I made a decision to write down one myself.

Final yr I “examined” this guide on college students and the outcomes have been fairly promising. Most of the scholars understood {the electrical} measurements and what most significantly, they discovered that this topic was attention-grabbing, and even fascinating.

Allow us to have a look at trendy measurement strategies, the current state and the longer term views. There is no such thing as a doubt that the longer term is reserved for pc measuring programs.

It’s no marvel that in the present day, when a easy electrical shaver is supported by a microcontroller that the measuring devices are additionally computerized. Not too long ago, pc measuring programs have turn into major instruments and the topic of analysis.

The result’s that many vital matters, mentioned on this guide as “Traditional Electrical Measurements” are in the present day on the periphery of curiosity. Nevertheless data of these topics is vital to grasp the ideas of trendy measuring devices.

Different consequence of the event of pc and microelectronics supported measuring programs is that they’re now additionally obtainable to nonspecialists.

Right this moment, what was reserved completely in previous, measuring units as prime quality analogue to digital converters or amplifiers, at the moment are obtainable to all at modest costs. Consumer pleasant software program akin to LabVIEW helps within the design of subtle measuring devices.

So-called clever sensors are in the present day designed in “plug and play” know-how, prepared to attach into worldwide pc networks.

Thus at the moment, the measurement approach is open to everybody (together with individuals removed from electrical engineering) and you will need to present them, easy methods to carry out the measurements appropriately.

 

This brings us to the elemental query: which data about measurements is indispensable? After discussing with many college colleagues, training trade engineers and of course college students, the proposal of contents for such indispensable topic was formulated.

However it appeared that to current such topics greater than a thousand pages guide was advisable. Due to this fact, the entire programme was divided into two clearly separated components:

“Principles of Electrical Measurements” and “Software of Electrical Measurements in Science, Business and On a regular basis Life”.

This primary half is offered on this guide. I perceive the “Principles of Electrical Measurements” as the entire data, frequent for all sorts of electrical measurements.

These frequent topics embrace most of all sign processing strategies (digital and as nicely analogue), basic measurement strategies, strategies of estimation of accuracy and uncertainty of measurement outcomes.

Information acquisition and sign conditioning, utility of computer systems and digital sign processors in measurement and digital measurements strategies.

When such topics are understood (for instance, after studying this guide, I hope) it must be less difficult to adapt to the extra sensible topics:

“Software of Electrical Measurements” – sensors, measurements of electrical and non-electrical portions, non-destructive testing and materials analysis, design of measuring devices, and many others.).
