Intelligent Insulation Resistance Tester
Darui Electric recommends：
型智能数字绝缘电阻测试仪采用嵌入式工业单片机实时操作系统, featuring a perfect combination of digital analog pointer and digital segment display. This series offers multiple voltage output levels (250V, 500V, 1000V, 2500V, 5000V, 10000V), large capacity, strong anti-interference, synchronous analog pointer and digital display, dual AC/DC power supply, simple operation, automatic calculation of insulation indicators (absorption ratio, polarization index), and power-loss protection for measurement results. It is an ideal instrument for measuring insulation resistance of large transformers, instrument transformers, generators, HV motors, power capacitors, power cables, and lightning arresters.
产品特
1. Multiple voltage output options (250V/500V/2500V/5000V), (5000V/10000V), with measurement range up to 0~400GΩ.
2. Dual-mode synchronous insulation resistance display. The analog pointer allows easy observation of insulation resistance variation range, while the digital display provides precise measurement results.
3. Embedded industrial MCU with real-time operating software system. High automation and strong anti-interference capability. The instrument automatically calculates absorption ratio and polarization index without manual intervention.
4. User-friendly interface with power-loss protection for measurement results. Continuously stores up to 19 measurement records.
5. When the instrument generates high voltage, an audible alert sounds with corresponding display indication.
6. Built-in residual high-voltage discharge circuit automatically discharges residual HV from the tested equipment after measurement.
7. Dual AC/DC power supply, equipped with rechargeable batteries and AC adapter.
8. Portable design for convenient field operation.
9、高压短路电流≥3mA，是测量大型变压器、互感器、发电机、高压电动机、电力电容、电力电缆、避雷器等绝缘电阻的理想测试仪器。
