10A/20A/40A Transformer Direct Current Winding Resistance Test instrument
Summary
Transformer dc resistance is transformer manufacturing of semi-finished products, finished products testing, installation, commissioning test and power sector preventive test will measure project, can effectively find the transformer coil material selection, welding, loose connection parts, short, break the blemish such as manufacturing and running after the existence of hidden dangers.In order to meet the needs of transformer dc resistance rapid measurement, it has developed a new generation of CT series dc resistance tester.
The instrument adopts the new program-controlled linear constant current source technology, with large output current, current gear, small volume, light weight, etc.
The machine is controlled by a single-chip microcomputer, automatic complete self-checking, data processing, display, save, print, and other functions, with sophisticated electronic measuring technology, makes the instrument is of high precision and wide measuring range, easy operation, can realize the sensibility of transformer and voltage transformer resistance rapid measurement.
Advantage
1.Using high precision electronic measuring technology and high-performance single chip microcomputer, makes the instrument has high measurement precision and numerical stability, good repeatability.
2.Instrument can choose appropriate according to the load current, the current gear, the biggest can output 10A current.
3.With printing, storage, real-time view the data, and other functions.
4. Big screen display, menu operation, friendly interface, be clear at a glance, convenient operation.
5.Micro printer for thermal printer, speed, the surface can be installed directly printing paper.
6.With audible alarm automatic discharge and discharge instructions, and other functions.
