An oil tan delta test set measures the dielectric loss of insulating oil used in transformers, assessing oil quality and insulation integrity. For China’s manufacturers, OEM factories, wholesalers, and suppliers, this equipment ensures reliable transformer performance, early fault detection, and compliance with international standards, supporting efficient B2B operations.
How Does an Oil Tan Delta Test Set Work?
The oil tan delta test set applies a high AC voltage across an oil sample and measures the resulting phase difference between current and voltage. This phase shift, or tan delta, indicates dielectric losses which reflect contamination or deterioration of the oil’s insulating properties. Wrindu’s precise instruments provide real-time measurements for effective transformer oil diagnostics.
What Are the Benefits of Using Oil Tan Delta Test Sets in Transformer Testing?
Using oil tan delta test sets enables early detection of insulation degradation, moisture ingress, and impurities in transformer oil, preventing catastrophic failures and extending asset life. It supports manufacturers and suppliers in quality control, reduces maintenance costs, and ensures transformer safety.
Which Standards Guide Oil Tan Delta Testing?
International standards like IEC 60247, IEEE Std. C57.104, and China’s GB/T standards define test procedures, voltage levels, and acceptable tan delta values to ensure consistent, reliable transformer oil assessment. Wrindu’s equipment complies with these standards, making it suitable for China’s OEM factories and wholesale markets.
| Standard | Region | Key Focus | Purpose |
|---|---|---|---|
| IEC 60247 | Global | Dielectric loss measurement | Standardizes oil quality testing |
| IEEE C57.104 | Global | Transformer insulation diagnosis | Guidance for oil testing procedures |
| GB/T 507 | China | Oil dielectric strength and losses | Local compliance and best practice |
