Buchholz reléfunksjon

Buchholz stafett is an important protection accessory for oil immersed transformers.

It detects internal transformer faults by monitoring gas accumulation and oil movement.

How Does Buchholz Relay Work?

When a minor fault occurs inside the transformer, the insulation material or transformer oil may decompose and generate gas.

The gas moves into the Buchholz relay and triggers an alarm signal.

For serious internal faults, a large amount of gas is generated, causing rapid oil flow.

The relay detects this oil movement and sends a trip signal to disconnect the transformer.

Why Is Buchholz Relay Important?

Buchholz relay can help detect:

• insulation failure
• winding faults
• overoppheting
• internal short circuits

It provides early protection and reduces the risk of major transformer damage.

Where Is Buchholz Relay Installed?

Buchholz relay is usually installed between:

• transformer main tank
• conservator tank

It is widely used in medium and large oil immersed transformers.

A reliable Buchholz relay improves transformer safety and helps power systems operate more efficiently.
