Product Description

Transformer turns ratio bridge tester/Transformer ratio resistance measuring instrument/TTR tester

Product introduction
KDB-II automatic ratio group tester is a high voltage test equipment manufactured according to the "People's Republic of China power industry standard", designed according to the general technical conditions DL/T963-2005, according to the "power equipment handover and preventive test procedures", can effectively supervise the quality of transformer products factory and use process, prevent transformer turn to turn short circuit. Open circuit, connection error, voltage regulator internal failure or contact failure. To provide correct data for the parallel operation of transformers is a conventional equipment for testing transformer ratio groups.

KDB-II automatic variable ratio group tester is small in size, light in weight, high in precision and good in stability. It uses large screen Chinese character display, menu operation, friendly interface. The variable ratio group can be measured in one time.

Transformer turns ratio bridge tester/Transformer ratio resistance measuring instrument/TTR tester
Main functions and characteristics
1, automatic measurement of transformer gear;
2, test the ratio of high pressure to low pressure and phase Angle difference, automatically calculate the ratio error and group;
3, parameters set once, later can be directly tested, data saved together, printing can be completed at one time;
4, the instrument has a high and low voltage reverse connection, output fault and other state prompts, to achieve real intelligence;
5, the instrument has a powerful protection function, output short circuit does not damage the instrument;
6, the instrument input single-phase power supply, automatically generate amplitude adjustable, stable, phase constant three-phase (120 °) power supply;
7, can measure phase shift transformer. Rectifier transformer with multiple pulses. Type Z transformers - Test PT.CT;
8, the test output voltage is different frequency, the result is not affected by the power frequency power supply frequency and amplitude fluctuations:
9, six channels simultaneous sampling, to achieve three-phase simultaneous measurement;
10, there is no relay inside the instrument, the instrument can run normally for a long time;
11, the instrument adopts microcomputer control, equipped with 800×480 color LCD touch screen, high-speed printer, support external mouse, easy to operate;
12, the instrument can automatically save 1000 sets of data inside, can also be stored external U disk;
13, the instrument can survive word report, convenient data management and query;
14, the instrument input voltage range is wide, the wrong AC380V instrument works normally.
