Product introduction

NAYZC series transformer load switch tester is integrated testing device, used for measuring and analyzing the power transformers and special transformers with load switch electrical performance in the power system. It adopts microcomputer control, through the precision designed measuring circuit, that can realize on-load switch transition time, transition waveform , transition resistance , three-phase simultaneous and other parameters measured accurately. Users may need and site conditions , leads directly from the tap to measure , but also by the three-phase transformer casing and wiring direct measurement of the neutral point . Based on user need and on-site condition, can measure directly via a tap switch lead, and also can measure though transformer three-phase drive pipe and neutral point directly.

Transformer load switch tester, the measured data can be analyzed, stored and printed. Solve the problems of current power transformer on-load tap backward measuring methods, and no dedicated testing methods. In the process of electrical equipment preventive testing and transformers overhauling, it can diagnose the loaded tap switch potential trouble timely, it’s important to improve power system reliability.

Also called name

On-load tap tester, transformer load top switch tester, transformer load tap tester

The Characteristics of the products

NAYZC Transformer Load Switch Tester

Products Characteristics

1.Light oscilloscope function

Instrument is divided into three channels,which can be recorded simultaneously A, B, C phase ,the instrument can automatically capture and display the process of transition process transition resistance and time transition.Weather-proof,the functions is superior than light oscilloscope.

2.Strong integrate ability

Can realize on -load tap- measurement of various parameters just by a single instrument. Such as switch selection,switch whole process without opening the break point,transition waveform, transition time,transition resistance,three-phase simultaneous and so on. Match with the function keys,you can analyze the waveform of each time period and resistance.

3.Printout

NAYZC transformer load tap tester is equipped with a front plate counter top for high-speed printer paper.

4.With good anti-jamming performance.

All-aluminum chassis and instrument are equipped with power supply noise filter and anti-jamming circuit,can be tested in the weak power,strong electromagnetic interference field.

5.Data saved, data communicated.

The measured data and waveform can be stored in the instrument.The stored wave forms can up to 128 groups,will not be lost due to power off,on-site testing results can be stored via a dedicated data line to the computer by serial transmission of preservation.( Nanao Electric Wuhan Company send special software )
