High voltage hipot testing ensures leakage current is minimal and dielectric remains intact. Factors such as moisture, vibration, and wear can render electrical insulation ineffective and vulnerable to transients and other energy fluctuations. These tests can reveal common insulation issues, such as braided shielding, stray wire strands, corrosive or conductive contaminants around conductors, and much more.
Hipot testers are available with an AC, DC, or VLF option. An AC hipot test voltage changes polarity, alternating between positive and negative. Meanwhile, the DC hipot test slowly increases voltage, allowing current to flow in one direction. VLF hipots test AC medium or high voltage cables at a low frequency, determining the high voltage fields of high capacitance loads.
To verify electrical insulation and high potential, ATEC offers a range of precise high voltage hipot tester rentals at affordable rates from trusted manufacturers, such as Hipotronics and High Voltage Inc. We are also able to calibrate certain models at our in-house lab.
