HZKZ-20A power transformer load and no load loss tester

I. Overview

HZKZ-20ATransformer On-No Load Characteristics Analyzer is the latest product of Huazheng Electric Manufacturing (Baoding) Co., Ltd. The instrument adopts the popular ARM processor in this year, with 168M basic frequency and 128m memory, which can be expanded to 4G memory card. Using 7-inch high-definition color touch panel, combined with emwin display interface so as to make the instrument interface being friendly and operated in a simple way, it can be operated through the touchscreen without keyboard. The instrument support database and can be exported through USB disk or transmitted to computer via data wire.
  The circuit design of this instrument is exquisite and unique, which makes it superior in performance, powerful in function, small in size and light in weight. It can not only be used to test the on-no load parameters of transformer, but also measure the harmonic content and waveform in the field. The instrument can record the test curve of transformer under on-no load condition, then provide reliable basis for transformer fault analysis.


II. Main Functions And Characteristics

1. The instrument adopts 7-inch true color LED. It can measure voltage, current, angle, power and other electrical parameters, and it also can display the vector diagram of voltage and current, both of the displays are shown clearly and intuitively on the same screen.
2. It can measure the parameters such as no-load loss, load loss and impedance voltage, etc.

3. The instrument has the function of harmonic analysis. It can measure the 1-32 harmonic content of voltage and current applied to transformer and display bar graph as well as voltage and current waveform.

4. The on-no characteristic curve under different voltage and current can be recorded automatically during the test process of on-no load condition of transformer, which can be more convenient to analyze the characteristics of transformer and core.
5. With the function of data storage and data browsing, the instrument supports DBF database, and it can store test data or browse test records according to user requirements. The instrument also supports the USB disk export function, you can export the test data through USB disk, and the database supports the excel spreadsheet opening mode, which is convenient for editing, printing or archiving.
6. Operate with 7-inch true color touch screen, the GUI interface, with build-in 128M memory (extensible 4G memory card), it supports English and is easy to operate.
7. It is small in size, light in weight, accurate in measurement, no power off calendar and clock function, so it can store test time at any time.
