SPR Transformers Sudden Pressure Relay - Reliable Protection

SPR Transformers suddenly pressure relay is a type of protective relay that uses the rate of change of internal pressure in the oil tank as an electrical signal. It is used to safeguard the oil tank of equipment such as transformers, power capacitors, reactors, etc.

1. High Sensitivity with Selective Activation: Remains inactive in low-pressure gradient zones within the tank while responding sensitively in high-pressure gradient areas to ensure tank safety. Sensitivity can be customized per user requirements.

2. Wide Measuring Range: Can be installed at a vertical distance of 0–6 meters below the maximum oil level.

3. Dual-Channel Quick-Action Output: Provides two independent rapid pressure signal outputs.

4. Static Pressure Alarm (Ø80 mm Model): Equipped with a static pressure alarm function for enhanced monitoring.

5. Robust and Compact Housing: Machined from high-strength aluminum alloy, ensuring leak resistance, structural integrity, small size, and an aesthetically refined appearance.

6. On-Site Testing Enabled: Includes a user-friendly testing device for convenient field inspection.

7. Superior Environmental Resistance: Excellent anti-corrosion, waterproof, and dustproof properties
