Why is dielectric oil analysis crucial?
Dielectric oil analysis is a fundamental practice in maintenance, especially for transformers and other substation elements that use oils for insulation and cooling. In the following, we will explore the reasons why this analysis is crucial for safety and efficiency.
1. Preventive maintenance
One of the main objectives of dielectric oil analysis is to detect problems before an unscheduled equipment shutdown occurs. Through periodic analysis, the condition of the oil can be identified by assessing the presence of contaminants, such as water, solid particles and degradation products, which can compromise the insulating capacity of the oil.
On the other hand, dissolved gas analysis aids in the detection of incipient electrical faults. By addressing these problems in time, service interruptions and costly repairs can be avoided.
2. Prolongation of the equipment lifetime
Predictive maintenance, including oil analysis, helps to extend the service life of equipment. Oil in good condition not only provides insulation, but also helps to dissipate heat generated during operation. Maintaining these properties helps to maintain good equipment health.
3. Energy efficiency optimisation
The performance of electrical equipment is directly related to the quality of the dielectric oil. Contaminated or degraded oil can increase losses and decrease operational efficiency. By performing periodic analysis, you can ensure that the oil maintains its dielectric properties, which in turn optimises the energy efficiency of the system.
4. Regulatory compliance and safety
In many industries, dielectric oil analysis is a regulatory requirement. Complying with these regulations not only avoids penalties, but also ensures a safe working environment.
A bad quality oil can be a fire or explosion hazard, so regular testing is essential to maintain the safety of workers and facilities.
5. Tendency detection and maintenance planning
Dielectric oil analysis allows technicians to identify trends over time. By keeping a record of analysis results, patterns can be detected that indicate gradual deterioration of the oil or equipment. This information is very useful for maintenance planning, allowing interventions to be scheduled before failures occur.
Conclusion
Dielectric oil analysis is an essential practice that should not be overlooked. Not only does it help prevent failures and extend equipment life, but it also optimises energy efficiency and ensures safety. Investing in regular analysis is a smart decision that can result in significant savings by avoiding unscheduled downtime, extending equipment life and improving equipment performance.
