Power Transformer AC DC Oil Type Dry Type Hipot Withstand Voltage Tester
Types and Features
Oil type high voltage tester
| Strength |
Weakness |
| Oil as an insulating medium can provide very high insulation properties |
Oil needs to be replaced periodically and maintenance costs are high |
| Stable output voltage, able to output high voltage signals |
Easy to be contaminated, causing pollution to the environment |
| Can extend the service life of the equipment to a certain extent |
Large size, not easy to carry |
| Able to perform long time high voltage tests |
|
Inflatable high voltage tester
| Benefit |
Drawback |
| Easy to carry and low maintenance cost |
Gas as insulation medium, insulation performance is slightly inferior to oil type high voltage tester |

When is a test transformer used?
A test transformer is used in various electrical testing applications to generate a high voltage or high current output, or to step down voltage or current for measurement purposes. Some common applications of test transformers include AC high voltage testing of electrical equipment such as transformers, cables, and switchgear, as well as impulse voltage testing, partial discharge testing, and insulation resistance testing. Additionally, test transformers are used in laboratory experiments, research and development, and calibration of electrical instruments and meters.
