HZ1141 Transformer Oil Gas Content Tester
I.Overview
In order to prevent transformer failure better and more comprehensively, the power industry has set higher requirements for the safe operation of transformers at all levels, and the test requirements for the gas content of transformer oil have also increased accordingly.
The insulating oil gas content tester is based on the DL423-91 power industry standard and relevant national standards. It uses imported high-precision sensors and the latest sensor technology. The determination of gas content in ultra-high pressure oil-filled equipment is an ideal test equipment in the laboratory.
II.Main Tech Data
1. High-precision electronic differential pressure sensor: the resolution shall be no less than 0.1%。
2. Minimum detection limit: no higher than 0.2%。
3. Accuracy: the relative error of the results of repeated measurement shall not exceed the following values：
| Gas content in oil (volume fraction)，% | relative error，% |
| < 0.5 | 10 |
| 0.5 – 1.0 | 8 |
| 1.0 – 3.0 | 5 |
| > 3.0 | 3 |
4. Temperature control range of degassing chamber: from 5℃ to 70℃ above room temperature
