Description
Overview
The Tentech TM-25R is a high-frequency earth ground tester designed specifically for measuring the grounding resistance of transmission towers. Unlike conventional low-frequency ground testers that can be affected by interconnected tower ground systems, the TM-25R operates at 25 kHz to minimize the influence of adjacent pylons connected by guard cables.
