Description

Insulation Testing Device with 0-10 MΩ Monitoring Range Dual-Bus Monitoring and Hierarchical Alarms for Accurate Fault Detection

Insulation Testing Device
Functional Features
  • Monitoring range: 0-10 MΩ (extendable up to 100 MΩ), accuracy ±5%, resolution ≤1 kΩ
  • Dual-bus monitoring: Independently measures insulation resistance between positive and negative electrodes to ground
  • Supports hierarchical alarms (early warnings and alerts) with customizable thresholds
  • Branch circuit inspection: Identifies faulty insulated branches using sampling resistor switching
  • Distinguishes between fault types including single-pole grounding and bipolar unbalanced grounding
  • Adaptive monitoring mode: Automatically adjusts measurement modes based on system voltage fluctuations
  • Supports host, extension, and slave operation modes
  • Supports coordinated testing of system interconnection faults between master and slave devices
  • Supports main handset mode for split-screen designs
  • Compatible with both digital and analog leakage current sensors
  • Modular design with parameter import via USB drive
  • Flexible configuration: Integrates with DC monitoring devices or standalone human-machine interface
  • Automatic switching of bridge resistor values for 110V/220V system adaptation
