Company Profile

The company specializes in the research anddevelopment, production, sales, and service of electric power systemautomation testing equipment, providing customers with one-stopservices.

Product Introduction

  • Throughout transformer manufacturing and maintenance, IEC standards recommend ratio testing to ensure consistent performance in operation. The new ZWBB101 ratio tester addresses shortcomings of traditional methods.
  • Where bridges required single-phase readings with non-intuitive data and unit conversions, this instrument displays direct multi-phase results on a large high-resolution screen. Menu navigation is simple and intuitive.
  • Key applications include verifying ratio accuracy for semi-finished and finished units during production. It also checks newly installed and in-service transformers at utilities.
  • Tests evaluate ratio values as well as tap changer condition and potential issues like inter-turn faults or parallel switching ability.
  • By simultaneously examining all three phases, the device completes verification much faster with greater precision than sequential single-phase assessment. This improved efficiency supports quality control and operational diagnostics.
  • Complying with standards, the tester facilitates manufacturing quality assurance and condition assessment, overcoming obstacles of past bridge-based ratio evaluation. Intuitive menu drive operation streamlines the assessment process.

Functional Characteristics

  • This precision transformer tester features innovative three-phase inverter technology for improved accuracy and efficiency. Internally generated balanced voltages eliminate mains harmonic interference for more reliable readings.
  • Using three outputs accelerates assessment through simultaneous multi-phase measurement. Phase angles and transformer configuration are automatically determined from wiring groups.
  • Compatibility spans various device types like Z-transformers, rectifiers, grounders, furnace transformers and more. Protection functions maintain safety under various fault conditions.
  • Inverter power ensures stability versus traditional single-phase mains derived units. Reverse/fault protections safeguard the instrument and device under test.
  • Key parameters can be entered to automatically assess ratio values and tolerances, including non-uniform tap changers up to 99 positions verified.
  • A vivid LCD guides users through each step plainly in their language. Microprinter, ports and wireless options facilitate documentation.
  • Sealed housing withstands field deployment. An app connects the tester to smartphones via Bluetooth for remote display and archiving test records anytime via mobile access point.
  • Advanced features like three-phase excitation and integrated controls remove complexities, streamlining verification forAccuracy and user-experience.
