Description
Product Description

The HZS-20A is a portable single-phase 20A winding resistance tester designed for rapid, accurate measurement of transformer DC resistance. DC resistance testing is a mandatory procedure for semi-finished products, finished products, factory tests, installation, handover tests, and preventive maintenance by power departments. It effectively identifies manufacturing defects such as poor material selection, loose soldering, connection issues, missing strands, broken wires, and operational hazards.

To meet the need for rapid measurement of transformer DC resistance, our company has leveraged its technical advantages to develop this Transformer DC Resistance Tester.

  • Resists high heat, humidity, and salt spray for tropical island use
  • Runs stably at -40°C — cold-proof and anti-condensation
  • IEC compliant, with complete calibration certificates provided
  • Local support: spares, on-site training, and instrument calibration

Product Features
  1. For testing star-connected windings with a neutral point lead-out, the instrument can measure the resistance of phases A0, B0, and C0 simultaneously, saving test time.
  2. For Y and Δ-connected windings, the instrument can perform automatic three-phase testing and calculate the three-phase unbalance rate.
  3. The instrument features a magnetization testing method and a demagnetization function.
  4. It includes multiple protection features such as back EMF protection, open circuit protection, and power-off protection.
  5. The instrument has a wide measurement range.
  6. Features a non-volatile clock and date display.
  7. Equipped with a thermal printer for quick, silent printing.
  8. Compact and lightweight for easy portability.
