Ground resistance measurement, as the core safeguard of electrical safety, has evolved from cumbersome manual “megger” methods to an era of intelligent, non-contact testing. Clamp-on ground resistance testers have revolutionized ground system inspection with their non-destructive operation, user-friendliness, and high portability, becoming essential tools in high-risk industries like power, telecommunications, and rail transit. Within this technological wave, FUZRR is redefining industry standards through the synergistic innovation of its ES3022 series precision measurement platform and FR2000 series intelligent clamp meters.
I. Deep Expansion of Industry Applications & Pain Point Resolution
Full-Cycle Safety Assurance in Power Systems
During substation ground grid inspections, traditional methods require disconnecting ground wires and deploying auxiliary electrodes—inefficient and hazardous in high-voltage environments. FUZRR’s FR2000C+ features Ω+A dual-display technology, enabling simultaneous measurement of ground resistance (0.01Ω–1200Ω) and leakage current (0–20.0A). It rapidly diagnoses resistance anomalies caused by corrosion or degradation without power interruption, compressing hours-long tests to minutes. For new ground grid acceptance, the ES3022 series supports four-terminal precision measurement (±2% accuracy) with 400V/5A output, penetrating high-soil-resistivity environments to deliver stable data compliant with IEEE-81 standards.
Breakthroughs in Renewables & Complex Industrial Scenarios
- Telecom Base Station Lightning Protection: Mountainous terrain limits ground testing at remote sites. The FR2000A requires only clamping onto a ground lead, with its 55mm×32mm narrow jaw fitting dense wiring environments. 50V power-frequency interference rejection ensures accuracy in strong electromagnetic fields.
- Petrochemical Explosion Safety: All FUZRR products hold IECEx explosion-proof certification. The FR2000C+ uses a fully sealed spark-free structure, enabling direct use in Zone 1 hazardous areas (e.g., gas stations, oil depots), eliminating explosion risks from metal impacts during auxiliary electrode deployment.
- Rail Transit Dynamic Monitoring: Electrified railway catenary ground resistance degrades under train vibration. ES3022’s step voltage measurement locates high-impedance points in real time, preventing signal system malfunctions from abnormal rail potential.
Emerging Needs in Healthcare & Smart Cities
Hospital OR equipotential bonding resistance must be ≤0.1Ω. ES3022’s 0.000Ω resolution and milliohm accuracy detect micro-resistance changes. For security systems, camera ground failure may cause lightning damage. The FR2000 series supports 300-data-point storage and Bluetooth transfer, enabling city-wide ground status visualization via cloud analytics.
