Introduction: Transformers contain several critical components that ensure their efficient operation, protection, and longevity. Among these, the conservator, breather, explosion vent, oil temperature relay, oil drain valve, fins, level indicator, and Buchholz relay play vital roles in regulating oil levels, preventing faults, monitoring temperature, and ensuring safety. These elements help maintain the transformer's health by addressing oil expansion, air moisture absorption, pressure regulation, and fault detection. Understanding these components is essential for effective operation, maintenance, and fault prevention in transformers. CONSERVATOR: This is mounted on top of the oil tank. This should have oil two third of its volume and the remaining filled with air. The conservator is used to accommodate the expanded volume of the transformer oil when ever the oil gets heated up owing to loading of the transformer. Also when the oil cools down, the oil from the conservator ...
