Ground-Resistance Online Monitoring System
Three-pole/clamp-meter dual-mode online monitoring replaces manual inspection and prevents personal and equipment accidents caused by grounding faults.
Three-pole/clamp-meter dual-mode online monitoring replaces manual inspection and prevents personal and equipment accidents caused by grounding faults.
Based on FR-series three-pole monitors and FRP-series clamp-meter monitors, it delivers 7x24 continuous online ground-resistance monitoring. The FR series (fall-of-potential method) measures 0.01ohm to 200ohm for precise measurement of new grounding systems; the FRP series uses contactless clamp-meter measurement without auxiliary electrodes for rapid surveys of existing grounding systems, with an explosion-proof Ex ia IIC T4 option for petrochemical scenarios.
Industry Pain Points
Long Manual Measurement Cycles, Low Precision
Conventional ground-resistance measurement relies on periodic manual testing; cycles are long, efficiency is low, and data cannot be obtained promptly in bad weather.
Delayed Grounding-Fault Detection
Grounding status changes after lightning strikes or faults are not captured in time; delayed detection can lead to personal and equipment accidents.
High Risk of Manual Measurement in Hazardous Areas
Manual measurement in explosion-hazard zones such as petrochemical tank farms carries safety risks; ordinary test equipment cannot enter, leaving grounding unmonitored.
Difficult Scattered Multi-Point Management
Substations, telecom base stations and wind farms have widely distributed measurement points without unified aggregation or centralized management.
Solution Architecture
Layered architecture, a complete data loop from sensing to operation.
Core Capabilities
Three-Pole/Clamp-Meter Dual Mode
FR series supports precise three-pole (fall-of-potential) measurement; FRP series supports fast clamp-meter surveys without auxiliary electrodes, adapting to different scenarios.
High Precision, Wide Range
0.01ohm-200ohm measurement range with high precision and stability, meeting grounding standards across industries.
Multi-Point Synchronous Monitoring
Multiple monitors in one network acquire synchronously with centralized comparison and analysis, covering large distributed grounding systems.
Smart Trend Analysis
Automatic analysis of ground-resistance trends with seasonal/weather changes for scientific status assessment and tiered over-limit alarming.
Tiered Over-Limit Alarming
Configurable multi-level thresholds; automatic alarm push to responsible personnel via SMS/APP/email on exceedance.
Lightning-Event Logging
Automatic correlation with lightning-current data, recording strike time and ground-resistance changes to support lightning-protection analysis.
Data Loop
The complete data value chain: sense -> data -> AI -> warning -> control -> operation.
