Description

Overview

GAOTek insulation resistance meter finds extensive application in maintaining electrical equipment within transformer substations, power plants, and similar settings. Specifically designed for assessing insulation resistance (IR), absorption ratio (DAR), and polarization index (PI) across various high-voltage equipment such as switchgear, transformers, reactors, capacitors, motors, generators, cables, and more.

 

Features

  • Controlled by a microcomputer with menu-based operation displayed on a large LCD screen for consistent performance.
  • Resilient against strong electromagnetic interference, ensuring accurate measurements.
  • Offers substantial capacity for high voltage, resistance, and large load tests.
  • Built durable to withstand harsh working conditions, being shockproof, moisture-proof, and dust-proof.
  • User-friendly interface displaying precise results and data trends clearly.
  • Features comprehensive protection against short-circuit impact and residual voltages.
  • Provides seven adjustable voltage output steps from 50V to 5.0kV.
  • Allows continuous adjustment of high voltage output as needed.
  • Automatically measures various resistances and calculates absorption ratio and polarization index.
  • Measures resistance up to 10TΩ, switching ranges automatically for convenience.
  • Automatically records ambient conditions and test duration for accurate data.
  • Shows test duration and prompts auto-shutdown after 5 minutes of inactivity.
  • Safely discharges high voltage within 30 seconds post-measurement.
  • Stores up to 60 sets of measurement results with non-volatile memory for retention.
