Product Advantages
Prevents Power Failures - It detects moisture and contaminants in the oil before they cause internal arcing or short circuits, avoiding unexpected transformer breakdowns.
Ensures Operator Safety - Equipped with automatic arc quenching and safety interlocks, it protects personnel from high-voltage hazards during the test.
Saves Time & Reduces Errors - The fully automatic operation eliminates manual guesswork, delivering fast, accurate, and repeatable results in less time.
Lowers Maintenance Costs - It enables condition-based maintenance (test first, treat later), preventing unnecessary oil changes and extending transformer life.
Easy to Use Anywhere - Portable models allow for on-site testing at substations or remote locations, complying with international standards like IEC 60156.
Application of Transformer Oil BDV Tester
Power Transformers (Substations & Grids)
Regularly tests insulating oil in large power transformers to prevent grid failures and unplanned outages.
Distribution Transformers (Poles & Pad-mounted)
Ensures reliability of local transformers that supply homes and businesses, especially in aging networks.
Railway Traction Transformers
Maintains oil quality in transformers powering electric trains, preventing delays and safety hazards.
Wind Farm & Renewable Energy Transformers
Monitors oil in remote, harsh environments where vibration and moisture ingress are common.
Industrial & Manufacturing Plants
Tests transformers in steel mills, chemical plants, and factories to avoid costly production stoppages.
Circuit Breakers & High-Voltage Bushings
Checks oil-filled switchgear and bushings for dielectric strength, ensuring proper arc extinction.
Transformer Manufacturing & Repair Shops
Used for quality control of new oil and reconditioned oil before transformers are shipped or reinstalled.
Utility Maintenance & Field Service Teams
Portable testers enable on-site diagnostics at substations, offshore platforms, and remote locations.

The Transformer Oil BDV Tester evaluates the ability of insulating oil to withstand high voltage before breakdown occurs. Transformer Oil BDV Tester utilizes advanced technologies, including central processing units and large-scale integrated circuits to perform fully automated testing. Additionally, test results can be printed using a built-in micro printer.

FAQ
Q: Are you a factory or just a trading company?
A: Wuhan UHV Electric Power Technology CO.,Ltd. is an industrial and trade enterprise, with its own factory, self-produced and self-sold.which means you get factory-direct pricing and direct technical support without any middlemen. You are welcome to request a factory tour via video call or visit us in person to verify our production capabilities.
Q: How to test BDV of transformer oil?
A: Power on the BDV tester and apply voltage continuously and uniformly at a rate of 3–5 kV/s. Increase the voltage until breakdown occurs between the electrodes, and the tester trips (overcurrent or breakdown detection circuit activates).
Q: What is an oil BDV tester?
A: The BDV test ensures that the oil can withstand high voltages without breaking down, which is essential for maintaining the transformer's performance and safety. The primary purpose of the BDV test is to assess the oil's ability to act as an effective insulator.
Q: Can the goods be customized and how long is the delivery time?
A: After ordering the goods, we can use the latest technology to place orders according to the customer's special requirements. If there are no accidents, the delivery time is usually within 10 working days.
Q: What is after-sales service?
A: We provide free consultation services, one-year warranty, and use various methods such as email communication, video calls, and technical on-site visits to promptly solve any after-sales problems.
