What Is a High Voltage Tester?
A High Voltage Tester is an electrical testing device used to apply controlled high voltage to electrical equipment and evaluate its insulation capability. By detecting insulation breakdown, leakage current, and dielectric strength, the tester helps identify potential electrical defects before equipment is put into operation.
High voltage testing is commonly used for:
- Insulation withstand verification
- Dielectric strength testing
- Leakage current measurement
- Electrical safety inspection
- Preventive maintenance testing
During the testing process, the equipment under test is exposed to a specified voltage level. Engineers can analyze the test results to determine whether the insulation system meets required safety and performance standards.
Weshine high voltage testing equipment is designed to provide stable voltage output, accurate measurement, and multiple safety protection functions for laboratory and field testing environments.
AC, DC, AC/DC and VLF High Voltage Test Solutions
Different electrical systems require different testing methods. Weshine develops various types of High Voltage Testing Equipment to support a wide range of applications.
AC Hipot Tester for Withstand Voltage Testing
The AC Hipot Tester is mainly used for AC dielectric withstand testing. It applies power frequency high voltage to verify whether electrical insulation can withstand operating stresses without breakdown.
Typical applications include:
- Power transformers
- Switchgear systems
- Electrical components
- Insulation materials
- Medium voltage equipment
The AC testing method is widely adopted for routine inspection, factory testing, and preventive maintenance.
DC Hipot Tester for High Voltage Insulation Testing
The DC Hipot Tester provides stable high voltage DC output for insulation evaluation and leakage current measurement.
Compared with AC testing, DC testing requires lower power consumption and is suitable for applications where long cables or capacitive loads need to be tested.
Common applications include:
- Power cable testing
- Cable fault prevention
- Transformer insulation testing
- Electrical equipment maintenance
AC DC Hipot Tester for Flexible Testing Requirements
The AC DC Hipot Tester combines AC and DC withstand voltage testing functions, allowing users to perform multiple insulation tests with one integrated system.
This type of equipment is suitable for:
