YD series oil transformer, also known as test booster, which test insulation strength under specified voltage for various electric products, components, insulation materials. It can test products insulation level, find insulation defect and judge overvoltage ability. It is widely used in power station, power supply and distribution system and research institute.
Features
1. Single phase core-type with high-quality cold-rolled silicon steel sheet, steel clamp as fastening mode;
2. The design of high voltage coil is cylindrical multi-level tower type, rolled by high quality polyester enameled wire and HV insulation material;
3. Low coil outside, coil is an independent winding;
4. Octagonal shell, a movable wheel can be installed for 10kVA or more testing transformers, easy to move;
Important Tips
AC and DC can be dual-used, change test parameters subject to above table, the parameters of the rated DC voltage 1.4 times more than rated AC voltage, DC rated current 0.7 times more than AC current.
