BeiDou-synchronized
Full-Station MOA Arrester Synchronous Live-Line Tester
A distributed design based on a BeiDou synchronous clock, achieving ns-level synchronized acquisition across multiple sensor groups. Sensors network over on-site wireless with built-in lithium batteries — no external power or comms cabling. The terminal automatically analyses each arrester’s resistive and fundamental leakage-current components and generates a test report.

Portable
Impulse Grounding Resistance Tester
Directly measures impulse grounding resistance, comprising a mobile impulse-current generator, a charge/discharge control box and an analysis unit. Compliant with GB/T 17949.1-2000, it outputs 8/20μs or 4/10μs impulse current waveforms, overcoming the large errors of the traditional impulse-coefficient conversion method.
