Transformers are one of the indispensable components of any electrical application and their primary function is to facilitate the flow of energy from one point to another. Their reliability and durability are mainly a function of maintenance regimes of which transformer fluid analysis is central.
By doing so, it also assists in determining the potential problems affecting the transformer before they become severe. In this article, the author discusses the roles of transformer fluid analysis, the various approaches, and the advantages of having the longest operational transformers.
Understanding Transformer Fluid: The Lifeblood of Electrical Systems
Transformer fluid also known as dielectric oil plays a very vital role, especially in transformer systems. It also serves as an insulating layer, facets heat, and shields interior parts from contaminants in the surrounding environment. The material can also denature over time due to exposure to heat, electrical sparks, and impurities present in the environment. The functionality of this fluid is checked regularly to make sure that its aspects of insulation, as well as cooling capabilities, are not lost to the functionality of the transformer or equipment.
Why Analyze Transformer Fluid? Unlocking Hidden Issues
One of the benefits of Transformer Fluid Analysis is that it can help to detect internal issues that are not easily seen from the outside. High levels of dissolved gases can suggest overheating or electrical faults, while high moisture levels can weaken the insulation.
Foreign particles, both from the environment and from the wear of the grinding elements, hurt the efficiency of the process. Such problems are identified in advance through transformer fluid analysis, thus reducing the chances of their occurrence and subsequent transformer failure.
Key Techniques in Transformer Fluid Analysis
Different techniques are used in analyzing transformer fluid and all have their objective towards different aspects to give a complete analysis. Several tests, such as dissolved gas analysis (DGA), show the existence of gases generated due to insulation failure or thermal abuse. Moisture content testing is a method used to determine the water content in the fluid, which degrades the insulation’s ability.
Dielectric breakdown voltage testing determines the electrical strength of the fluid under test. Other methods like the Acid number test and Furan analysis reveal the status of chemical transformations and state of degradations of insulations respectively. Combined, every kind of method provides a comprehensive picture of the overall condition of the transformer.
Benefits of Regular Fluid Analysis for Asset Management
The main benefits of implementing transformer fluid analysis into a regular maintenance schedule include the following: It helps reduce the costs of maintenance because the faults will be detected early before expensive repairs or replacements are required. Transformers’ reliability increases dramatically if potential issues are resolved before they affect the performance.
The overall lifetime of transformers is also increased because corrective measures are taken before the long-term degradation of the equipment takes place. Furthermore, it is also important to analyze the company’s fluency to determine if there are any leaks or contaminants that may harm the surrounding environment.
