1. What Is a 5 kV AC Withstanding Voltage Tester?
An AC withstanding voltage tester, also known as an AC hipot tester or dielectric withstand tester, is an electrical safety testing instrument used to evaluate the insulation strength of an electrical product.
During testing, the instrument applies a specified AC voltage between selected electrical points. It monitors the leakage current and identifies abnormal conditions such as insulation breakdown or excessive current.
Typical test applications include:
Electrical components and assemblies
Transformers and motors
Power cables and electrical wires
Switches, plugs and sockets
Household electrical appliances
Electronic instruments and equipment
Insulating materials and electrical accessories
The test voltage and duration depend on the product design, applicable safety standard and manufacturer's test procedure.

Technical note: The published HM2670 specification above describes AC output. DC output voltage and DC testing performance have not been confirmed in the available model-specific specifications. If DC withstand testing is required, the output configuration should be confirmed with Goldhome before ordering.
4. Working Principle of the HM2670 AC Withstanding Voltage Tester
The HM2670 performs dielectric withstand testing by applying an AC high voltage to the insulation under test and monitoring the resulting leakage current.
The process can be divided into four main stages.
4.1 Test Voltage Generation
The instrument generates an AC test voltage within its specified output range.
The operator selects the required test voltage according to the product's insulation requirements and approved test procedure.
4.2 Voltage Application
The high-voltage output is connected to the specified test points of the product.
For example, a test may be performed between live electrical circuits and accessible conductive parts, depending on the product design.
4.3 Leakage Current Monitoring
During the test, the instrument monitors the current flowing through the insulation and associated capacitive paths.
If the measured current exceeds the preset limit or an unacceptable breakdown condition occurs, the tester can identify the abnormal test condition according to its protection design.
4.4 Test Result Evaluation
The test result is evaluated using the selected test voltage, leakage current threshold and test duration.
A product passes only when it meets the specified test criteria throughout the test.
5. AC Dielectric Withstand Testing Applications
5.1 Transformer Insulation Testing
Transformers contain insulation systems between windings, between windings and the core, and between electrical circuits and grounded structures.
An appropriate AC hipot tester can be used for specified insulation withstand tests on suitable transformer components or assemblies. The required test voltage must match the transformer design and applicable procedure.
5.2 Motor and Generator Testing
Motor and generator insulation systems must withstand electrical stress during operation.
AC dielectric withstand testing can be used in manufacturing inspection and maintenance procedures to evaluate insulation integrity.
5.3 Cable and Wire Testing
Electrical wires and cables require suitable insulation performance for safe operation.
A 5 kV AC withstand voltage tester can support testing of suitable cable and wire products, provided that the required test voltage, leakage current and load are within the instrument's ratings.
5.4 Electrical Components
The HM2670 can be applied to dielectric withstand inspection of suitable electrical components, including:
Power plugs and sockets
Switches and connectors
Electrical assemblies
Insulating components
Household electrical products
5.5 Electronic Equipment Manufacturing
Manufacturers of electronic instruments and electrical appliances may use AC hipot testing as part of their production quality control process.
The test arrangement must account for sensitive electronic circuits and the product's specified insulation barriers.
6. How to Perform an AC Hipot Test
The following is a general testing workflow. The exact test connections, voltage and duration must follow the applicable product standard and approved testing procedure.
Step 1: Inspect the Test Object
Check the product's insulation condition, terminals, enclosure and electrical connections.
Confirm the rated voltage and identify the required insulation test points.
Step 2: Prepare the Tester
Connect the HM2670 to the specified AC 220 V power supply.
Check the test leads, grounding arrangement and safety protection before operation.
Step 3: Set the Test Parameters
Set the required parameters:
AC test voltage
Leakage current threshold
Test duration
The selected values must be appropriate for the test object and applicable standard.
Step 4: Connect the Test Object
Connect the high-voltage lead and return lead to the specified test points.
Ensure the test object is isolated from its normal power supply and other external circuits.
Step 5: Start the Test
Start the test using the instrument's operating procedure.
Apply the specified voltage and monitor the leakage current during the test.
Step 6: Evaluate the Result
Check whether the test voltage remains within the required range and whether the leakage current stays below the specified limit.
Any breakdown, flashover or abnormal test condition should be investigated.
Step 7: Discharge and Disconnect
After testing, allow the test object to discharge safely. Verify that no hazardous voltage remains before removing the test leads.
7. AC Hipot Tester vs. DC Hipot Tester
AC and DC withstand voltage testers use different test voltage waveforms and may be selected for different test requirements.
| Comparison | AC Hipot Tester | DC Hipot Tester |
|---|---|---|
| Test voltage | Alternating voltage | Direct voltage |
| Electrical stress | Alternating electric field | Unidirectional electric field |
| Capacitive current | Present during AC testing | Mainly transient charging current after voltage application |
| Typical applications | AC dielectric withstand testing | Specified DC insulation withstand applications |
| Test procedure | Defined AC voltage and duration | Defined DC voltage, charging behavior and duration |
| Selection basis | Applicable standard and insulation design | Applicable standard and insulation design |
A product advertised as an AC/DC hipot tester should have confirmed AC and DC output specifications, including voltage range, current limit and test modes.
For the HM2670, the currently published model-specific parameters confirm AC testing. Its DC capability should not be assumed without additional technical documentation.
8. How to Choose a Suitable 5 kV Hipot Tester
When selecting a 5 kV withstand voltage tester for manufacturing or laboratory use, consider the following factors.
1. Test voltage range
Confirm that the equipment can provide the voltage required by the product test procedure.
2. Leakage current setting
The adjustable leakage current threshold should cover the required acceptance criteria.
3. Output capacity
Check whether the rated output power is sufficient for the test object. Capacitive loads may draw additional current during AC testing.
4. Test duration
Confirm that the timing function supports the required test period.
5. Protection functions
Consider overcurrent protection, breakdown detection, emergency stop and other safety functions.
6. Operating environment
Check the required power supply, temperature, humidity, ventilation and installation conditions.
7. Communication and automation
For production-line applications, consider whether the tester needs external communication, automatic test sequencing or integration with other inspection equipment. Confirm these functions against the actual model configuration.
