Technical specifications
Key features of Oil-Immersed AC Hipot Test Set
Faq of Oil Immersed AC DC Hipot Test Equipment
- YDJ Pointer 5kVA Oil-Immersed AC Test Transformer is a traditional high-voltage testing device that uses oil insulation to enable stable AC withstand voltage tests on electrical equipment. Its 5kVA capacity supports testing of medium-sized apparatus like transformers and cables, while the pointer-style analog interface provides clear voltage/current readings. The oil-immersed design ensures effective heat dissipation and reliable insulation performance, making this classic tester suitable for industrial and laboratory applications requiring robust dielectric strength validation.

Faq of Oil Immersed AC DC Hipot Test Equipment
- 1. What tests are oil immersed AC/DC hipot testers mainly used for?
- Oil immersed AC/DC hipot testers are mainly used to generate high-voltage alternating current and conduct insulation and voltage withstand tests on power equipment, such as power cables, transformers, switchgear, insulators, circuit breakers, and insulation tools.
- 2. Do oil immersed AC/DC hipot testers need regular oil changes?
- No need for frequent oil changes. Under normal use, transformer oil only serves as insulation and heat dissipation, and will not be consumed or deteriorated. It is recommended to conduct an oil pressure test every 2-3 years (to check for moisture), and if it is qualified, continue to use it. Even if oil filtration or replacement is required, the cost is much lower than that of inflatable gas replacement.
- 3.What is the difference between oil immersed and dry-type test transformers?
- Oil immersed AC/DC hipot testers have better insulation performance, higher output voltage, better heat dissipation performance, and longer continuous working time. Dry type test transformers are lightweight, easy to transport and move, and more suitable for testing at lower voltage levels.
- 4. What voltage levels can oil immersed AC/DC hipot testers provide?
- Common output voltage levels include 50kV, 100kV, 150kV, 200kV, 300kV, etc. Higher voltage levels can also be customized according to customer needs.
