Why is it important to measure?

As article 2 of European Directive 374 of 25 July 1985 states that ‘also electricity’ is a ‘product’, equating it with any other type of ‘movable goods’, the first, immediate answer is: to be able to market the product elctricity.

Using a more sophisticated argument, even if it is limited to the management aspects of a power plant (thus ignoring all the technical and scientific questions), there is a clear need in today’s market to contain and reduce costs and ensure continuity of service.

It has thus become vital to thoroughly familiarise oneself with the operation of an electric plant in order to be able to optimise:

  • Consumption,
  • Load curves,
  • Harmonic interference,
  • Voltage disturbances,
  • etc, i.e. all the elements that contribute to increase efficiency, improving competetitivity, and, an important factor today, reducing harmful emissions in the environment.
Lastly, still from the management point of view, measuring and monitoring electrical quantities enable fault prevention to be optimised and maintenance to be scheduled owing to early identification of problems that results in greater protection not only of the plants but also of the objects connected to them.

Applicational contexts

An efficient system of measuring and monitoring electrical quantities is important for ensuring the success of all initiatives that require:

  • Energy costs to be contained;
  • Quality energy supplies;
  • Continuity of service of the plants.

Specifically, achieving the above objectives requires the activities to be implemented that are set out in the flow chart in Fig. 1.1.

    i. I want to measure the harmonic generated in power system at home,where should I place my harmonic meter.Will be after the service meter or at the input terminal of the distribution board(DB)

    ii. If I want to measure the harmonic effect of on the grid due to my dc rectifier where should I connect the harmonic meter

    iii. Please I need a book to read on power quality measurement

    Thanks
