Buchholz Relay: Protecting Your Transformer's Integrity

The Buchholz relay is a vital piece of safety equipment for oil-filled power transformers, offering crucial protection against internal faults. This highly reliable device detects and signals potentially catastrophic events, preventing significant damage and costly downtime. Our Buchholz relays are designed and manufactured to the highest industry standards, guaranteeing dependable performance and longevity.

Key Features and Benefits:

• Early Fault Detection: The relay sensitively detects the presence of gas and/or excessive oil movement within the transformer tank, indicative of internal arcing, overheating, or other serious problems. This early warning system allows for prompt intervention, minimizing the risk of major damage.
• Dual Protection: Our relays offer dual protection mechanisms:
  • Gas Detection: A sensitive diaphragm within the relay responds to the accumulation of even small amounts of gas produced by internal faults. This triggers an alarm, alerting operators to a potential problem.
  • Oil Movement Detection: A tilting mercury switch within the relay senses rapid or excessive oil movement, which can be caused by a sudden short circuit or other disruptive events. This triggers a more immediate tripping response.
• Reliable Operation: Constructed with durable, high-quality materials, our Buchholz relays are designed to withstand the harsh operating conditions of a power transformer environment. Their robust construction ensures years of reliable operation and minimal maintenance.
• Simple Installation and Maintenance: The relay is designed for straightforward installation into the transformer's conservator tank. Routine maintenance is minimal, further contributing to its cost-effectiveness.
• Clear Indication: The relay provides clear visual and electrical signals indicating the type of fault detected (gas or oil movement). This allows operators to quickly diagnose the problem and take appropriate action.
• Compliance with Standards: Our Buchholz relays are manufactured to meet or exceed all relevant industry standards and safety regulations, ensuring compliance and peace of mind.
• Customizable Options: We offer a range of customizable options to meet your specific needs, including different contact configurations and mounting styles. Contact us to discuss your requirements.
