Key TakeawaysRegular Maintenance is Crucial: Routine inspections, oil analysis, and electrical testing are essential for preventing transformer failures and extending their operational lifespan.Advanced Diagnostics Improve Reliability: Techniques like Dissolved Gas Analysis (DGA) and Frequency Response Analysis (FRA) help in early detection of potential faults, allowing for proactive maintenance.Preventive vs. Predictive Maintenance: Combining preventive maintenance with predictive strategies, s …

There are various types of transformer used in the electrical power system for different purposes, like generation, distribution, transmission and utilization of electrical power. The power transformer is one of them and it is very vital in the transmission process.The power transformers are used in the transmission networks of higher voltages. They are larger in size and are rated as follows 400 KV, 200 KV, 110 KV, 66 KV, 33 KV. They are mainly rated above 200 MVA. Power transformers are mainly …

A transformer is an electrical device that helps to distribute electrical energy evenly among multiple circuits. This is done by increasing or decreasing the voltage in the original circuit. Transformers are especially useful in cases where circuits need to be isolated from each other or when the voltage in one circuit needs to be changed. The transformer is made up of two coils that are not connected electrically. They work based on the Faraday principle of mutual induction. This means that whe …

When people here the word transformers, many things come to mind, could be the movie “The transformers” could be what transforms a thing from one state to another. But electrical transformers changes the electrical signal strength from one level to another. So how does a power transformer work?A power transformer works by taking advantage of the fact that an electrical current can create a magnetic field, and that a changing magnetic field can induce an electrical current. In a transformer, an a …

Power transformers are stationary electrical machines used for transforming power from one circuit to another without changing frequency. This is a very basic definition of transformer. Since, there is no rotating or moving part, so a transformer is a static device. Transformer operates on an A/C supply. A transformer works on the principle of mutual induction. As the leader in distribution of power transformers in Nigeria, GZ has understood how to ensure power transformers are well maintained a …
