• 1、AC and DC High-Voltage Output: It generates a high-voltage AC output for power frequency withstand tests. With an optional high-voltage silicon stack, it can also provide DC high voltage for leakage current and withstand tests.

• 2、5kVA Power Capacity: The 5kVA rating provides sufficient power to effectively test capacitive loads such as medium-voltage cables, transformers, and switchgear.

• 3、Pointer-Style Analog Display: It features clear, pointer-style analog meters for real-time, visual monitoring of output voltage and leakage current, providing direct and reliable readings without the need for complex setups.

• 4、SF6 Gas Insulation: The transformer uses SF6 gas as its insulating medium, offering superior dielectric strength and arc-quenching properties compared to air or oil.

• 5、Simple and Manual Operation: The tester is designed for straightforward, manual operation with intuitive controls, ensuring reliability and ease of use in demanding environments. It includes overload and short circuit protection.

• 1、Superior Portability: The SF6 gas insulation allows for a significantly more compact and lightweight design. It is 40-65% lighter than oil-immersed transformers of the same rating, making it exceptionally easy to transport and handle on-site.

• 2、Maintenance-Free Operation: As a gas-insulated unit, it is "spotless and greaseless," requiring no oil-level checks, filtration, or leak monitoring, which saves time and eliminates the risk of oil spills.

• 3、Excellent Insulation Performance: The SF6 insulation provides higher dielectric strength with minimal corona discharge, ensuring reliable test results and a long service life.

• 4、Proven Reliability: The simple, analog design with manual controls is robust and dependable, ideal for applications where advanced digital features are not required and straightforward functionality is essential. Its rugged construction is well-suited for tough industrial environments.

• 1、Power Utilities and Substations: Used for routine withstand voltage testing of transformers, circuit breakers, cables, and other medium-voltage equipment during commissioning, maintenance, and fault diagnosis.

• 2、Industrial Maintenance: Employed by industrial plants for periodic testing of motors, generators, switchgear, and other electrical apparatus to ensure insulation integrity.

• 3、Field Testing and Repair: Its light weight and simple operation make it ideal for on-site testing of equipment in substations, construction sites, and other field locations.

• 4、Educational and Training Laboratories: Used in vocational schools and training centers to teach the principles of high-voltage testing and dielectric withstand.

• 1、What is the main difference between the YDQ and GTB series hipot testers?
  The primary difference is the insulation medium. The YDQ series uses SF6 (gas) insulation, while the GTB series uses a dry-type (air) insulation. This makes the YDQ significantly lighter and more compact than the GTB for the same rating, but it requires careful handling of the sealed gas system. The GTB is generally more robust for heavy-duty field use.
• 2、What are the advantages of SF6 gas insulation?
  SF6 gas has superior dielectric strength, allowing for much smaller and lighter transformers compared to oil or air-insulated units of the same rating. It is also non-flammable, inert, and maintenance-free, eliminating oil-related issues.
• 3、Can this tester perform DC tests?
  Yes, it is an AC/DC tester. To perform DC tests, you need to connect an optional high-voltage silicon stack (rectifier) to the output of the test transformer, which converts the AC output to DC for leakage current measurement and withstand tests.
• 4、What safety features are included?
  The tester includes overload and short circuit protection . When used with its control console, it also typically features zero-start protection and an emergency stop, ensuring safe operation.
• 5、Where is this tester most commonly used?
  This tester is commonly used for routine withstand voltage testing on medium-voltage equipment (e.g., 6-35kV class) in utilities, industrial plants, and laboratories, especially where portability and simplicity are valued over digital features.
