FAQs

A Ground Bond Tester checks the integrity of the protective ground circuit by applying a high current and measuring the resulting voltage drop. It ensures that the connection can safely carry fault current without posing a shock or fire hazard.

Yes. Models like the 95X Series 952i, 954i, and 959i and V7X Series V74, V77, and V79 include full ground bond testing capabilities in addition to AC/DC hipot, IR, and continuity testing.

Up to 40A RMS in the 95X series and up to 30A RMS (42A peak) in the V7X series, meeting or exceeding global safety standards.

No. Vitrek combines both functions into one tester, reducing hardware costs, simplifying setup, and increasing test efficiency.

Yes. Vitrek testers meet UL, IEC, CSA, and EN requirements, making them ideal for global product certifications.

Both the 95X and V7X series offer micro-ohm-level resolution. For example, the V7X provides resolution down to 0.1 mΩ at higher currents, ensuring precise detection of even minor resistance increases in the ground path.

Yes. Vitrek testers use 4-terminal Kelvin measurement configurations for ground bond testing, allowing highly accurate low-resistance readings by eliminating lead and contact resistance effects.

The 95X series provides a 6.5V RMS compliance voltage, which can be user-limited with 0.01V resolution, allowing flexible testing across various load conditions and industry standards.

Yes. Vitrek’s 95X testers provide in-phase and quadrature (out-of-phase) current measurements, giving users deeper insight into resistive and reactive components of the test signal.

Yes. Both 95X and V7X testers can control Vitrek 964i HV switching systems, enabling up to 256 channels of fully automated ground bond and hipot testing across multiple test points.

Vitrek testers include TLSS™ Test Lead Safety Sense, GFI and SFI fast shutdown, and safety interlock systems, ensuring operator protection during high-current tests.

Yes. With rugged construction, fast cycle times, and fan-free design (V7X), Vitrek testers are built for high-throughput environments like automated production and quality control lines.

A ground continuity test checks for the existence of a ground connection using a low current (usually <1A). In contrast, a ground bond test subjects the ground path to high current to confirm its ability to carry fault-level currents without excessive resistance or failure.

Electrical and electronic devices that must comply with UL, IEC, EN, or CSA standards often require ground bond testing. This includes products in the medical, industrial, automotive, and consumer electronics sectors.

Most compliance standards require ground bond testing with AC current ranging from 10A to 40A, depending on the classification of the product and its intended use.

Yes. Ground bond testers from manufacturers like Vitrek support automation through SCPI command sets and interfaces like USB, Ethernet, RS232, and GPIB. Many models also integrate with HV switch systems for fully automated, multi-point testing.
