Failure or malfunctioning of equipment and machinery leads to low production rates in industries. Since low production isn’t a new thing in businesses, experts are working hard to ensure they maintain a continuous work environment in their industries.
An excellent way of maintaining efficient performance of equipment and machines is ensuring there is high power quality in electric systems. But then, how can they achieve this?
And what are the results after obtaining a high power quality in industries? In the article today, readers will understand more about power quality and more about best power quality analyzers.
What is Power Quality?
This refers to the sufficiency and cleanliness of power supplied to electrical equipment and machines. There are several power quality issues that affects power quality, they include power factor, voltage and current instability, harmonics and many others.
All these issues leads to a lot of consequences. In the list is high energy consumption costs, machines or equipment failure, and high costs of maintenance.
What is the Solution to Power Quality Analyzer Issues?
Since the entire power quality issues gives rise to a number of challenges, there is need to address the problem as early as possible. A solution to this issue is energy management.
Most people get themselves busy addressing the high costs of energy at home and in industries. What they forget is that power quality need assessment as part of any energy management issue. This brings us to the question, how can experts address the power quality issue?
Before getting through how to address these issues, we can group power quality issues into three broad categories. They include poor power factor, harmonic currents and voltages and voltage instability. Let’s have a close look at how to address every category of power quality.
Poor Power Factor
Before we address the issue, what is poor power factor? The problem of poor power factor develops when there is excess reactive power circulating in an electrical system.
Excessive reactive power doesn’t do any great thing in the general production activities and increase energy costs. A solution to poor power factor is considering Power Factor Correction to eliminate excessive reactive power in electrical systems.
Harmonic Currents and Voltages
Issues of harmonic current and voltage normally develops from the power end users. The problems are introduced into the system by end user electrical devices. These devices distort the wave form of AC thereby increasing the consumptions rate.
How can you solve harmonic voltages and currents problem? There are two ways you can solve such problems in the system.
Introducing harmonic filters can help to eliminate all harmonics from the system to keep it more effective for use. You can also consider introducing reactors in the system to neutralize harmonics thereby resulting into usage of efficient and cost effective power.
This power quality problem arise by the effect of high and low voltage chipping into the system. Bothe high and low voltages affects equipment and production in different ways.
Low voltage in the system can cause reduced productivity while high voltage deteriorates performance of equipment. A solution to voltage instability is optimizing voltage flowing through the system.
Analyzing Power Quality Readings
Most people in the past days made analysis of power quality readings just through a look at the current and voltage parameters. Things have changed and analysis to buy power quality analyzer data is complicated in a way. Analysis process of data recorded from these devices becomes complicated due to a number of reasons. They include;
- Different sensitivity levels of devices connected to power system
- Varied running durations of equipment connected to the power system
- There are more devices connected to electric systems.
All these aspects and many more makes the analysis process complicated than before. There is need for technicians to consider continuous and close monitoring of systems to record valid data for fast analysis process.
You also require to employ a flexible data analysis system that can handle all the measurements from single phase power quality analyzers. Moreover, the analysis you employ should be capable of maintaining databases to use in carrying out different applications.
Let’s look at an example of few power quality issues like transients and harmonics in this situation. When doing an analysis, we normally characterized by transients by the real or actual waveform. In the analysis, an analyst can create summary descriptors of other parameters to help in the analysis process.
When dealing with the RMS variations, analysts characterize obtained value alongside the minimum voltage magnitude measured in an event. The method works well when dealing with single events. If you deal with the entire system, how will you go about it?
In such situations, you are required to involve all events that might have taken place in a certain period. Lastly, in the analysis process, harmonics get characterized by individual event current and voltage snapshots. Since current and voltage changes keeps varying, they are never represented with a single event but a multiple of snapshots.
When characterizing current and voltage harmonics, statistics and time trends of snapshots are of great importance. For the analysis process of power quality to bore results, parameters in all levels of systems must play a role.
These include data from the power distribution system to the end users. Inclusion of data from all levels is important since portable power quality problems arise within all levels of the system.
Power quality analyzers metering plays an important role in our electric systems. They help in monitoring systems and provide hint whether there is clean and sufficient energy supplied to equipment. In the event of abnormality in the system, data is recorded and used power quality analyzers by technicians to solve the problem.
Since power quality problems develop in all levels of systems, there is need to find them solutions to prevent challenges that might develop afterwards. Learn how to measure and analyze power quality analyzer readings to maintain equipment running effectively all through.
