Transformer relay panels are one of the most important components of electrical protection systems within substations. They continuously monitor the transformer's performance in terms of current, voltage, and temperature, and immediately detect any abnormal conditions such as short circuits or overloads.
The importance of this panel lies in preventing minor faults from turning into catastrophic problems that could lead to the complete shutdown of the substation. For example, if a transformer overheats or experiences an unbalanced current, the panel immediately disconnects the circuit, protecting valuable assets and prolonging their operational life.
These panels are typically used in power plants, large transformer centers, and large industrial projects that rely on high-capacity transformers.
