Line Loss Tester

New Products / New Technology

The ZH-8231 Line Loss Tester is a highly targeted and practical professional instrument. It was meticulously developed to address two challenging issues in low-voltage distribution‑area operations: identifying abnormal line‑loss points and mapping the topology of power supply lines. In areas where line losses are abnormal or network topologies are unclear, this device enables rapid and accurate localization of line‑loss anomalies and systematic reconstruction of the network topology.

High-Voltage Switch Contact Performance Comprehensive Tester

New Products / New Technology

It is suitable for measuring the loop resistance and contact pressure of梅花 contacts in high-voltage switchgear within substations, power plants, and switchgear stations. It is also applicable to comprehensive performance testing of switchgear contacts during manufacturing or maintenance. Additionally, it can be used for the integrated measurement of contact pressure and loop resistance in high-voltage isolating disconnectors.
