Product Description:
Insulation resistance tester is widely used in maintenance of electrical equipment in transformer substation,
power plant, etc. The electrical insulation tester is suitable for carrying out measurement of insulation resistance (IR), absorption ratio (DAR) and polarization index (PI) of all kinds of high voltage equipment, including switchgear, transformers, reactors, capacitors, motors, generators and cables, etc.
Electrical Insulation Tester Features
1. 7 "HD color touch screen with spare stylus pen.
2. Insulation resistance range 0- 50TΩ(10KV)
3. Short circuit current ≥5 mA
4. Automatic display polarization index (PI), induced electric absorption test values than (DAR), capacitance, leakage current. Automatically store test data for 15 seconds, 1 minute, and 10 minutes.
5. It can measure leakage current Ix and voltage in real time, and display the curve of voltage, current and resistance .
6. Strong anti-interference ability, suitable for measuring in strong electromagnetic interference environment.
7. Short circuit protection function. In case of short circuit, the instrument will automatically cut off the power within 5 seconds.
8. When the measurement is completed, ir testers will discharge automatically and display the discharge process in real time.
9. Advanced memory with time/date stamp
10. Power supply : rechargeable lithium ion batteries, battery operating time can be up to 6-12 hours.
11. Internal thermal printer.
12. With RS232 serial interface, able to data communicate with computer.
Electrical insulation tester advantage
Accurate Measurement:
Resistance testers electric provide precise and reliable measurements of electrical resistance, allowing technicians to assess the integrity of conductive pathways, components, and circuits accurately. This helps identify open circuits, short circuits, and resistive faults in electrical systems.
Versatility:
Insulation resistance meters can measure resistance across a wide range of values, from fractions of an ohm to megaohms, making them suitable for testing various types of electrical components, including wires, cables, resistors, switches, connectors, and semiconductor devices.
Diagnosis of Faults:
Digital insulation testers are valuable tools for diagnosing electrical faults and troubleshooting problems in circuits and systems. By measuring resistance values at different points in a circuit, technicians can pinpoint the location of faults, such as loose connections, corroded terminals, damaged components, or faulty wiring.
Preventive Maintenance:
Implementing routine resistance testing as part of a preventive maintenance program helps identify potential issues before they escalate into costly failures or downtime. By monitoring resistance values over time, technicians can detect gradual degradation or wear in electrical components and take proactive measures to address them.
Safety Assurance:
Resistance testing helps ensure the safety and reliability of electrical systems by verifying that conductive pathways have the appropriate resistance values to carry current safely. This reduces the risk of overheating, arcing, and electrical fires caused by excessive resistance or poor electrical connections.
