Chi tiết Sản phẩm

HIOKI AC GROUNDING HiTESTER

MODEL :

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.
