Pressure Vacuum Gauge with Bleeder Valve for Power Transformers

A Pressure Vacuum Gauge with Bleeder Valve is an essential safety and monitoring device used to measure the internal pressure and vacuum levels of power transformers. It helps operators maintain stable operating conditions, prevent tank deformation, and ensure safe breathing of the transformer during load and temperature changes.

Why It’s Important

Transformers undergo pressure variations due to temperature fluctuations and oil expansion. Accurate pressure – vacuum monitoring is crucial to avoid excessive positive or negative pressure that may damage the transformer tank or compromise safety.

Key Features

• Dual-scale pressure & vacuum measurement for precise monitoring
• Integrated bleeder valve for controlled air release during installation and maintenance
• Rugged, corrosion-resistant body suitable for outdoor and high-voltage environments
• High-sensitivity diaphragm or bourdon mechanism for reliable readings
• Clear, easy-to-read dial with protective glass cover
• Standard mounting design for compatibility with various transformer models

Benefits

• Maintains safe internal pressure levels
• Prevents tank bulging or vacuum-related damage
• Supports efficient transformer breathing and oil movement
• Enables quick venting and pressure balancing through the bleeder valve
• Ensures long-term accuracy and reliable operation

Applications

• Power transformers
• Distribution transformers
• Utility substations
