Qualitative Analyzes
Power quality analysis is a topic of growing importance. This evaluation service includes measurements of harmonics, voltage fluctuation, short-term voltage variation (VCTD) and unbalance. Such analyzes make it possible to characterize the power quality at a given point in the electrical system, assess the causes of possible problems, test analyzers, check the immunity of different types of equipment, identify and diagnose consumer or electrical network problems.
However, it is normal for companies to be concerned only with the continuity of electricity, through the service provided by the concessionaires, and with the interruption of supply, generating losses that vary from the stoppage of engines and equipment to the interruption of activities and operations carried out. by employees.
But it is also a fact that companies do not give importance to the quality of electrical energy and even if there is no interruption in the supply of energy, there are several types of disturbances that are detected through energy analysis and that cause excessive heating in electrical circuits and electronics, the consequence of which is to accelerate the burning of electronic components, in addition to partially harming operating systems, with possible crashes and damage to magnetic files.
With this, we can certainly say that the quality of energy is directly related to maintenance costs and loss of productivity.
The “quality of electrical energy” is related to deviations that may occur in the intensity, waveform or frequency of voltage and/or electrical current. And it is also related to permanent or transient interruptions that affect the performance of electrical energy.
We know that, mainly in places where the power supply is provided at low voltage, there are greater problems related to power quality, and one of the causes is the generation of harmonic waves in the installation itself and those received by cogeneration, especially by generator sets. and applications of frequency inverters or no breaks.
-Overheating of equipment such as motors and transformers;
-Malfunction of equipment and reduction of its useful life;
-Low energy efficiency;
-Damage to sensitive devices such as computers and control systems;
-Interferences in electronic communications;
-Increased investments in installations due to the high number of electrical breakdowns;
-Penalties imposed by regulators because of pollution generated by facilities.
Hence the importance of companies investing in managing the quality of electricity. And to measure quality, the power analyzer is essential equipment these days.
This accessory is used by specialized technicians and electricians who provide services in homes, businesses, industries, schools, hospitals, among other establishments that require stricter control over the quality of electricity.
The main differential of an energy analyzer is its ability to analyze the electrical energy parameters, that is, measure the quality of supply, intensity and also any failures that could jeopardize the supply on site. The device also allows capturing voltage events and generating accurate reports on the situation, as well as recording and storing data for long periods. Another differential point for measuring the quality of electricity with an analyzer is the ability to monitor the needs of the network that supplies the location and, therefore, point out any measures to adjust failures. Technicians and electricians can also measure harmonic distortion caused by electronic loads, capture voltage swells and dips, and configure equipment according to waveforms and trends.
Normally, energy analyzers are manufactured with a robust and compact design, precisely to facilitate the work of technicians and electricians and to allow their movement to different sectors of a residence or industry. It is important to emphasize that it is essential that the professional responsible for measuring the power quality has experience in using the equipment, as well as in the performance of the function.
Energy analyzers may contain different accessories depending on the manufacturer, but most have the following complements to the main equipment:
-Flexible suitcase for safe transport;
-Flexible current probes;
-Customized software;
-Tension clamps and auxiliary cables;
-Customized Color Identification Set;
-International standard AC adapter and interface cable;
-Printed and multilingual manual.
However, it is fundamental to analyze the quality of electrical energy in any type of customer, whether it is a residence, a business or industry. The service is fundamental because it punctuates any failure in the system, from installations to equipment.
In addition, he also points out precise and effective solutions to save energy and ensure the proper performance of all equipment installed in the customer’s local electrical network. The general result is the improvement of production costs, generating greater profitability and safety for the system operation.
