Why Every Transformer Needs a Buchholz Relay || Tach Engineer || 2023

Buchholz Relay is an important component used in transformers to provide an extra layer of protection and to detect faults or problems that could potentially lead to serious damage or safety hazards.

The main reason why we use Buchholz Relay in transformers is to detect the presence of gas or oil in the transformer tank. In the event of a fault or failure, such as insulation failure or overheating, gases and oil vapors can be produced in the tank. Buchholz Relay detects these gases and oil vapors, triggering an alarm or shutting down the transformer before any further damage occurs.

Buchholz Relay is also able to detect minor faults, such as a small amount of gas produced by the overheating of windings or oil, before they develop into more serious problems. This early detection helps to prevent damage to the transformer and reduce the need for costly repairs.

In addition, Buchholz Relay is a reliable and low-maintenance protection device that provides an extra layer of safety and protection to transformers. Its effective and efficient performance has made it a standard component in transformer protection systems, ensuring the safety and reliability of electrical systems.
