Mô tả sản phẩm
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
