HZBD-IV Variable Frequency Transformer Comprehensive Characteristic with Printing

Product Overview

In a power system, the transformer is a core component, and its long-term reliable operation is crucial to the stability and reliability of the entire system. The HZBD-IV is designed with fully intelligent one-touch testing functions for DC resistance and turns ratio testing. Based on the set testing parameters, it intelligently identifies the current tap position of the transformer, then automatically tests and saves the turns ratio and DC resistance data for that tap position.

  • 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
