Power Quality Measurement and Analysis Basics
The study of the power distribution parameters is considered by many as complicated work in engineering. However, calculation of the power quality analysis in UAE is so important for mechanics, electrical engineers, and technicians, who fix problems with the machinery today — and for contractors maintaining electrical systems once built — like the use of the clamp ammeter to figure out why the overloaded circuits are constantly running.
It is time to investigate the matter, figure out the cause, and undertake corrective steps in the absence of any electrical grid. It is designed to facilitate the proper operation of loads by an electrical delivery grid. If a load does not work properly it should be considered that the efficiency of the electric power in the device is one potential reason. The measurement analysis of electric device parameters was called power quality evaluation, regardless of whether it is used for troubleshooting or to collect baseline data.
Measurement Tools
For power quality evaluation, many measuring tools are available. Power quality analyzers are the most common instruments for observing readings in real-time and gathering information to be downloaded for review. Although some are permanently mounted on the delivery system, handheld analyzers, particularly troubleshooting, are required for many applications.
Handheld power efficiency analyzers (usually 4 lb – 5 lb) are reasonably lightweight and test a range of parameters. The most popular ones are: voltage, amperage and frequency, dips and swells, the factor of power, harmonic currents, the resultant factor for distortion and crest, power and electricity, voltage and current unbalance, intruding current values, and light flicker. If the analyzer tests and tracks those fundamental criteria, you can deal with most issues related to power efficiency.
Process
● Planning continues with the execution of a power content survey. Identify the purpose and write it in a notebook or binder which is used for the organization and preservation of the data during the whole process. Begin with a decent one-line diagram of the delivery structure of the building.
● If a general energy efficiency survey is carried out to collect benchmark data for potential comparisons — or to help spot any latent issues around the delivery of electricity that might occur — track the point of services as closely as possible. However, cautious calculation close to the operation usually requires significant quantities of usable fault current.
● In the factory, the delivery system starts to “drill” according to the one-line diagram. Get data at each system’s root separately extracted. For eg, after the transformer is 480V to 208Y120V, take recordings on the first panel or switchboard. Make sure your sketches are labelled and take lots of notes.
● Digital cameras are working well for quick recording of name site data and later for precise positions of contacts. Notice the conditions of the plant and all operational machinery. Print digital pictures and hold in the notebook binder all survey data. These notes are useful as details are analyzed and further studies were undertaken.
Analyzing the Data
The perception of power efficiency parameters and their features must be taken into account, be they the observation of real-time values on the analyzer color screen or the power quality analysis of downloaded data on the laptop back to the store. IEEE power quality requirements and NFPA 70B are ideal guides to consider terminology, challenges, and disciplinary measures in terms of power quality. Every vendor suppliers software for their individual test equipment to help analyze the results.
Final Words
Performance in three main fields can be related to success in the calculation and study of power output. Set priorities and prepare the survey by analyzing diagrams in a line to define monitoring points. Learn how and how to use the features of the test equipment to collect the values needed. Finally, know what to do when observing data if it is downloaded to the device in the field or afterward. Obviously, it is a crucial step in addressing energy efficiency problems to learn how to measure electrical parameters effectively associated with the accurate operation of machinery.
