Buchholz Relay Explained | Working, Construction, Principle & Operation in Transformer Protection
What is a Buchholz Relay and how does it protect oil-filled transformers?
In this video, we dive deep into the construction, working principle, and operation of the Buchholz Relay — a critical safety device used in transformer protection systems. You'll understand how it detects internal faults, activates alarms, and trips circuit breakers to prevent transformer damage.
Learn how both minor and major faults are detected using this gas-actuated mechanical relay, including the importance of its float, mercury switches, and baffle plate.
