Hipot / High Voltage Tester
High-voltage test instruments (hipot testers) ensure the safe use of electrical products. They enable safe testing of electrical objects and help prevent electric shock.
Hipot testers measure insulation strength and leakage current under AC (alternating current) and DC (direct current). The testers deliver reproducible results (pass/fail) and integrate seamlessly into test benches and automated test systems via common interfaces.
For IEC/EN-compliant workflows—from first prototypes through series production. Depending on your requirements, we offer a selection of high-quality test equipment for high-voltage testing in our shop.

Facts about HV tests, high-voltage testing, and insulation resistance measurement
High-voltage testing (HV test) with hipot instruments
This test is also called an HV test or dielectric withstand test. For this measurement method, the high-voltage test is performed with an AC or DC hipot tester, depending on requirements. The high-voltage test instruments verify the insulation of electrical products. During the measurement, the device under test is exposed to a significantly higher test voltage than in normal operation. The tester provides an adjustable output voltage and continuously acquires voltage and current to ensure safety. This test proves that the device under test offers sufficient dielectric strength even at high voltage. Thanks to the high-voltage test, the HV instrument remains safe for users even at elevated operating voltage.
The precisely measured leakage current must not exceed a predefined limit. The test is carried out in accordance with the relevant standards for electrical safety.
Hipot testers can be connected via USB so that software can document and clearly display measurement results during the test— a practical solution for automated workflows.
Insulation resistance measurement
In this high-voltage test, the HV instrument analyzes the insulation, i.e., the insulation resistance of the device under test. This measurement technique ensures safe operation of the tester while the test voltage is applied. The measurement is performed between all live conductors and to the enclosure.
From compact testers to modular high-voltage systems — equipped with advanced software, this measurement technology enhances safety.
