DH-18D Insulator Zero-Value Tester Display Video
Product Overview
The DH-18D Insulator Zero-Value Tester is primarily employed for detecting concealed faults within 35–1000kV suspension insulators or for laboratory testing of suspension insulators. It can measure the distributed voltage or insulation resistance of each insulator under live (or de-energised) conditions, to assess the condition of insulators. This facilitates the timely replacement of insulators with non-compliant distribution voltage or insulation resistance values, thereby ensuring the reliable and safe operation of transmission lines.
