    • Product Introduction

    ZC-254B Three channel partial discharge detector is a new digital liquid crystal display partial discharge detector developed by our company to solve the problems of low brightness and short service life of the oscilloscope tube of the traditional partial discharge instrument.

    The instrument has the advantages of high detection sensitivity of mature products, large sample capacitance coverage, wide range of applicable samples, complete input units (detection impedance) and multiple frequency band combinations (nine kinds). The operation, structure and installation form are fully compatible with previous models, which is convenient for the upgrading of existing system equipment.

    • Product Features

    1、After the partial discharge signal is digitized, the liquid crystal display is used to replace the traditional oscilloscope display.

    2、 The operation is exactly the same as the traditional analog partial discharge test instrument, which is simple and easy to learn.

    3、Freely select ellipse, straight line and sine display mode

    4、Digital windowing technology can avoid the influence of interference on measurement.

    5、Any phase windowing, single window or double window optional, and the ellipse rotates 150 degrees.

    6、It can freeze the current discharge map, and observe and analyze the static partial discharge pulse.

    7、The current discharge spectrum can be saved to realize the traceability of test results.
