♦Small size, light weight, accurate measurement


Product Introduction

ZWKZ204 transformer no-load characteristic analyzer is the latest product launched by our company. The instrument adopts today’s popular ARM processor, 168M main frequency and 128M memory, which can be expanded with 4G memory card. The LCD adopts a 7-inch high-definition color touch screen, combined with the emwin display interface, making the instrument user-friendly and easy to operate, and can be operated with full touch screen without a keyboard. The instrument supports databases and can be exported via a USB flash drive or transferred to the backend computer via a data cable.
The circuit design of this instrument is exquisite and the idea is unique, which makes it have superior performance, powerful functions, small size and light weight. It can not only test the no-load parameters of the transformer, but also measure the harmonic content and waveform on site. The instrument can record the no-load test curve of the transformer to provide a reliable basis for transformer fault analysis.

Functional Characteristics

1.The instrument uses a 7-inch true color LCD, which can measure electrical parameters such as voltage, current, angle, power, etc., and can display vector diagrams of voltage and current, with a clear and intuitive display on the same screen.
2.It can measure the no-load loss, load loss, impedance voltage and other parameters of the transformer.
3.The instrument has a harmonic analysis function, which can measure the 1-32nd harmonic content of the voltage and current applied on the transformer, and can display bar graphs and voltage and current waveforms.
4.It can automatically record the no-load characteristic curves under different voltages and currents during the no-load test of the transformer, making it easy to analyze the characteristics of the transformer and iron core.
5.It has data storage and data browsing functions. The instrument supports DBF database and can store test data or browse test records according to user needs. The instrument also supports USB flash drive export function, which can export test data through USB flash drive. The database supports excel spreadsheet opening method, which is convenient for editing, printing or archiving.
6.It adopts 7-inch true color touch screen operation, emwinGUI interface, built-in 128M memory (expandable 4G memory card), supports English input, and is simple and convenient to operate.
7.Small size, light weight, accurate measurement, non-power-off calendar, clock function, and can store test time at any time.
