Ensuring Transformer Reliability through Advanced Insulating Oil Moisture Tester
Maintaining the quality of insulating oil is crucial for the safe and efficient operation of power transformers. Moisture contamination in transformer oil weakens the insulation strength, accelerates the aging process, and causes equipment damage. Regular monitoring with specialized detection equipment helps utility companies and industrial facilities prevent unplanned power outages and extend the lifespan of their equipment.
The moisture content of insulating oil poses a hidden danger to transformers.
Moisture in insulating oil directly affects the safety and efficiency of transformers. Even the smallest amount of water can degrade insulating performance, increase dielectric losses, and accelerate equipment aging, ultimately leading to short circuits, damage, or costly, unplanned downtime. Traditional moisture analysis methods are often slow, inaccurate, or complicated, preventing users from quickly addressing moisture-related risks. The HM401 directly addresses these issues, offering a simplified solution for proactive oil quality monitoring.
Key advantages: speed, accuracy and easy use
The HM401 insulating oil moisture meter redefines moisture detection with industry-leading features:
Laboratory-accurate results: adopts the advanced coulometric Karl Fischer titration method, which complies with international standards GB/T 7600, ASTM D1533 and IEC 60814. Detects moisture content between 1 ppm and 10,000 ppm (0.0001% and 1%) with a margin of error of ≤±2%, ensuring reliable data for critical decision-making.
Fast test cycle: completes a single sample test in just 3-5 minutes, a 70% reduction compared to traditional titrators, enabling high throughput for busy laboratories and on-site inspections.
Fully automated operation: users only need to inject 2-5 ml of oil sample; the meter automatically performs titration, endpoint detection and result calculation. No professional technical knowledge is required, eliminating human error.
Easy-to-use interface and data management: Equipped with a 5-inch color touchscreen, this device displays real-time humidity values, test curves, and historical records (up to 2,000 entries). Results can be printed directly via the built-in printer or exported to a computer via USB for easy report integration.
Durable design for diverse environments
Designed to withstand harsh industrial conditions, the HM401 offers unmatched flexibility and reliability:
Stable performance: A high-purity titration cell made of corrosion-resistant materials ensures compatibility with all types of insulating oils (mineral oil, synthetic oil, natural ester oil) and provides consistent results at temperatures between 5°C and 40°C.
Portable and compact: Weighing only 8 kg, the compact design is ideal for both laboratory use and on-site testing at substations or remote power projects - without the need for large equipment or sample transport.
Low maintenance: The tester's self-cleaning function and replaceable reagent cartridge simplify maintenance, reducing operating costs and downtime.
