BR Series Buchholz Relay

Overview 

Transformers outages have considerable impact on the power grid. During their operation, certain phenomena contribute to the degradation of the insulation and generate dangerous gas and oil flow inside the tank.

The Buchholz relays are designed to monitor and rapidly react to internal gas accumulation and oil flow changes. It provides a prompt alarm or trip signal allowing the operator to shut down the transformer quickly and prevent further damage.

Features:
● Flexibility in product options
● Robust design and field-proven reliability
● Precision and tested quality
● Quick Quotes and Deliveries

Our Buchholz relays are designed to detect the faults and minimize the propagation of any damage by controlling the gas accumulation and oil flow inside the transformer. Examples of faults that can cause gas accumulation or strong oil flow are:

● Short-circuited core laminations
● Broken-down core insulation
● Overheating of windings
● Bad contacts
● Short-circuit between phases
● Earth faults
● Puncture of bushing insulators inside tank
● Falling of oil level due to leaks
