AC GROUNDING HiTESTER 3157

Protective Ground Tester Indispensable for Standards Certification



The Hioki 3157 is an AC ground bond tester designed for protection circuit testing of a wide range of electrical equipment, including industrial machinery, medical equipment, and measuring instruments using a constant current system, enabling it to provide stable output current.

Key Features
• Easily perform protective continuity testing in compliance with international safety standards and laws
1) Protective continuity resistance measurement for medical devices and general electrical devices
2) Ground connectivity testing when installing electrical machine tools and distribution panels
3) Testing of protective grounding and isopotential grounding work for medical equipment
4) Evaluation of contact status using large currents
• Feedback control system that is capable of applying a stable current even with a fluctuating load
• Soft-start function that checks the connection to the device under test before applying the current
