  • Product Introduction

    Low voltage short circuit impedance test is the identification of operation in the transformer under the impact of short-circuit current, which is the most direct method to check the winding deformation of the transformer affected by mechanical impact in the transportation and installation; it for the judgment of transformer can put into operation has important significance, is one of the examination to determine whether the transformer requirements disintegration
    ZC-204B Transformer short-circuit impedance tester has the internal adjustable power output and do not need the outside pressure regulator, only need to provide 220V power supply can be tested, especially suitable for the field of 110kV level and above the main transformer for low voltage short circuit impedance measurement.

  • Product Features
    1. This transformer tester has adjustable power output, single-phase and three-phase transformers. It can be used to complete all winding measurements. It only needs to connect the wires once, and the test and wiring are simple. The instrument uses phase-locked loop technology to synchronize sampling and communication. Signal, measurement data is accurate.
    2. Test and algorithm is to meet the<< DL/T1093-2008 power transformer winding deformation detection and judgment >>, and automatically calculate the short-circuit impedance, reactance and inductance value of each phase.
    3. Test data can be imported into the computer to facilitate further analysis or storage; support external power supply, expand the test power.
    4. Through the anti large screen liquid crystal, in the sun can be clearly displayed; all Chinese menu and operation tips, simple and intuitive operation.
