YDQ Gas Type AC/DC Hipot Test Set
Product Introduction
YDQ series AC Hipot Test Set are essential equipments during electrical equipments tests and preventive tests. With the development of China's power industry, people required higher about the voltage class of testing transformer, and the traditional oil / dry type test transformer cannot meet the requirement in volume, weight, and functions.
AC Hipot Test Set compared with the traditional oil / dry type test transformer, 20%-60% reduction in weight (depend on the voltage and capacity class), without oil pollution, voltage class can up to 300kV, less than 2Pc under rated voltage. It is especially suitable for condition of working or moving frequently.
4、It offers significantly higher insulation strength compared to oil-immersed transformers and produces minimal corona discharge.

Frequently Asked Questions
1 . Can it be used in conjunction with a series resonant system?
Okay. Inflatable test transformers can be an important component of AC withstand voltage systems, and can also be combined with series resonant devices, high-voltage dividers, control consoles, protective resistors, and other equipment to form a complete withstand voltage test system according to test requirements.
2. Is it suitable for on-site testing?
Yes, it is. Due to its lightweight, compact structure, and convenient transportation, the inflatable test transformer is highly suitable for mobile testing scenarios such as substations, power plants, construction sites, and equipment maintenance sites.
3. Does SF₆ gas need to be replenished frequently?
Under normal circumstances, frequent supplementation is not necessary. The equipment adopts a sealed structure, and the SF₆ gas leakage rate is extremely low. Confirm that the air pressure is normal during regular maintenance and inspection. If the air pressure drops after long-term use, supplement the gas according to the instructions.
