HM-YDQW Description
HM-YDQW PD free AC High Voltage Test Set is completely customized according to customer's requirements.It's used to make ac voltage withstand test, partial discharge test test , hipot for 1 minute at rated power output.It is equipped with excellent protection device, and increased current limiting resistor to ensure the test device won't be destroyed when the tested object is breakdown.
HM-YDQW Features
-
Low-PD AC high-voltage source
The PD-free test transformer provides up to 80 kV AC with a specified PD level of ≤5 pC at rated voltage and ≤1 pC at 50 kV.
-
Automatic test sequences
Set the voltage, rise speed and withstand time in advance and let the control console run the programmed test sequence.
-
Manual control when needed
Manual mode allows engineers to control the voltage directly when carrying out special or non-standard test procedures.
-
Built-in protection
HV current, LV current and voltage limits can be set through the control console to help protect the test system and test object.
-
High-voltage measurement
A 100 kV AC capacitive voltage divider and peak voltage meter provide high-voltage measurement for the test system.
About the Product
- The HM-YDQW-10kVA/80kV is designed for users who need more than a basic AC high-voltage source.
- For a conventional withstand test, the main requirement may be reaching the required voltage and holding it for a specified period. For partial discharge testing, however, the test source itself also needs to maintain a low discharge background.
- The HM-YDQW system addresses both requirements by combining a PD-free AC test transformer with controlled voltage output and high-voltage measurement.
- The main test transformer, HM-YDJW-10kVA/80kV, has a rated capacity of 10 kVA, maximum AC output voltage of 80 kV, and rated output current of 125 mA. It is specified for one-minute operation at rated voltage.
- The system components can be configured according to the customer's testing requirements.

Products Application
The HM-YDQW-10kVA/80kV is suitable for applications requiring controlled AC high voltage.
-
AC Withstand Voltage Testing
Apply a specified AC voltage to electrical insulation or equipment and maintain the voltage for the required test period.
-
Partial Discharge Testing
Use the PD-free transformer as the AC high-voltage source where a low PD background is required.
-
Insulation Testing
Evaluate the insulation performance of electrical equipment and components under AC high voltage.
-
Laboratory Testing
Use automatic or manual operation for development, verification and diagnostic testing.
-
Production Testing
Automatic test stages can help standardize repeated AC high-voltage tests during production.
The actual test voltage, test time and acceptance criteria should always be determined according to the test object and applicable testing requirements.
FAQs
Q: Which AC high voltage test set is right for my application?
A:The right test set depends mainly on the required test voltage, test capacity, test object and whether partial discharge testing is required.
For applications requiring up to 80 kV AC and 10 kVA, the HM-YDQW-10kVA/80kV provides a complete solution with a PD-free test transformer, automatic control and high-voltage measurement.
Q: What should I consider when choosing a PD-free test transformer?
A:
he main factors include:
Required AC test voltage
Rated capacity
Test object capacitance
PD background level
Required test duration
Voltage control method
Measurement and protection requirements
For PD testing, the specified PD level of the test transformer should be considered alongside the requirements of the overall measurement system.
Q: Do I need an automatic AC high voltage test system?
A: Automatic control is particularly useful when the same test needs to be performed repeatedly.
It allows the operator to preset voltage levels, voltage rise speeds and withstand times, reducing repeated manual adjustments and making the test procedure easier to reproduce.
