Buchholz relay is used for the protection of transformers from the faults occurring inside the transformer. Short circuit faults such as inter turn faults, incipient winding faults, and core faults may occur due to the impulse breakdown of the insulating oil or simply the transformer oil.

Overview
A Buchholz relay is a protective device primarily used for the protection of transformers against internal faults. It is a type of oil and gas actuated relay that senses abnormal operating conditions within the transformer.
Function
- The Buchholz relay works by detecting the presence of gas or oil flow within the transformer tank.
- In case of an internal fault such as a short circuit or insulation breakdown, gas bubbles or oil flow will be generated, causing the relay to actuate.
Protection against internal faults
- The primary function of the Buchholz relay is to protect the transformer against internal faults.
- It can detect incipient faults that may lead to catastrophic failures if not addressed promptly.
Types of faults
- Internal faults such as partial discharge, arcing, or insulation failure can be detected by the Buchholz relay.
- External faults, on the other hand, are typically handled by other protective devices such as overcurrent relays or differential relays.
Importance
- Detecting internal faults early can prevent damage to the transformer windings and core, ultimately extending the transformer's lifespan.
- The Buchholz relay provides an additional layer of protection to ensure the safe and reliable operation of the transformer.
In conclusion, the Buchholz relay is specifically designed for the protection of transformers against internal faults. While it plays a crucial role in safeguarding the transformer from potential damage, it is not intended for protection against external faults.
