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.
HIOKI AC GROUNDING HiTESTER
モデル :
3157 (110V)
3157-01 (220V)
Protective ground tester indispensable for standard certification .
– The 3157-01 AC GROUNDING HiTESTER is designed to measure
whether the metal enclosure of an electrical equipment is connected to the ground terminal at sufficiently low resistance levels.
– It also can be used to evaluate the grounding conditions of large-scale electrical installations.
– Measurement is carried out by using a high current according to the specifications of the measurement object, and determining the voltage drop at the measurement point.
– Reference values are as set out in the various safety standards.
– The 3157-01 can carry out measurements in accordance with the stipulations of multiple standards.
