개요

KV-3100 Insulation Resistance Tester features a shockproof, dust-proof, and moisture-proof design, making it ideal for harsh working environments. It is an essential instrument. It is suitable for carrying out measurement of insulation resistance (IR), absorption ratio (DAR) and polarization index (PI) of all kinds of insulating materials and transformers, motors, cables and electrical equipment.

 

기능

  • 5-inch colorful touch screen displays test data simultaneously, making test operations and historical data viewing very convenient.
  • Insulation resistance range: 0.005 MΩ to 10TΩ.
  • Maximum output rated voltage reaches 8 levels: 50V, 250V, 500V, 1 kV, 2.5 kV, 5 kV.Maximum short circuit current: 7 mA.
  • High output power with strong anti-interference capability, ensuring stable testing in environments with large distributed capacitance (such as long cables) and high electromagnetic interference (such as substations).
  • Comprehensive measurement features : It includes theInsulation resistance test (IR), Polarization index test (PI)Dielectric absorption ratio test (DAR)Step test (STEP)、Ramp test (RAMP)、Dielectric discharge index (DD)、Distributed capacitance (CAP)、Voltage (V)
  • Customizable measurement modes: Users can select calculation formulas for PI, DAR, and DD, providing multiple options.
  • Customizable voltage settings: Test voltage and duration can be freely set for specific requirements.
  • Voltage monitoring: Automatically monitors the live voltage of the measured object. If the voltage exceeds 36V, testing is automatically prohibited to protect both the instrument and the operator.
  • With shockproof, moisture-proof and dust-proof structure,Durable double-shell structure with an IP65 protection rating.
