Product Description：
HIOKI 3157 Trueform Waveform Generator 交流接地電阻器
Designed to measure whether the metal enclosure of 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.
Description
- Easily perform protective continuity testing in compliance with international safety standards and laws (*1)
- 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
