Product Description

Product overview:

For the power system, transformers are the core equipment in the system, so the long-term and reliable operation of transformers will be related to the stability and reliability of the entire system. Before the newly installed transformer is put into operation and according to the preventive testing regulations of State Grid, it is required to conduct regular turns ratio or voltage ratio tests on the operating transformer. The traditional variable ratio bridge is cumbersome to operate, the readings are not intuitive, and necessary conversions are required. The test results are only the value of one phase ratio. This transformer ratio tester overcomes the shortcomings of traditional ratio bridge testing. The screen adopts a large high-resolution LCD display, which is convenient for on-site use. It has a Chinese menu prompt function, easy and intuitive operation, and can complete three-phase ratio testing in one go with fast testing speed and high accuracy.


Performance Characteristics:

1 Three phase CNC sine inverter power supply output, with soft start and soft stop functions, therefore fast testing speed and high accuracy.
2 Three phase transformer, single-phase transformer, PT, CT, Z-type transformer ratio, group, polarity testing function.
3 CT ratio polarity testing function.
4 During single-phase testing, it has the function of angle difference testing.
5 tap gear can be tested up to 99 gears.
6 The testing range is wide, with a maximum of 10000.
7 High and low voltage reverse connection reminder.
8 Output short circuit reminder.
9 Non power-off clock and date display; The data storage method is local storage, with 100 test data, and the stored data can be transferred to a computer (PC);
10 Thermal printer printing function.
11 Small size, light weight, easy to carry and use.
