Product Description

Product Description

In the power transformer semi-finished products, finished products in the production process, the new installation of the transformer into operation before and according to the national power ministry of the preventive test procedures, the requirements of the operation of the transformer turns ratio or voltage ratio test, you can check the correctness of the transformer turns ratio, tap changer condition, whether the transformer is short-circuited between the turns, whether the transformer can be operated in parallel. The traditional ratio bridge reading is not intuitive, to convert, can only be measured phase by phase.HZBB-VII transformer ratio tester overcomes the weakpoints of the traditional ratio bridge test, easy and intuitive to operate, the use of three-phase precision inverter power supply, fast testing, high accuracy.
 

Product Features

1, the instrument internal use of three-phase precision inverter power supply, eliminating the harmonic effects of the utility voltage during measurement, more accurate measurement. When the working power supply is generator, there is no influence.

2, the use of three-phase output voltage, improve the speed of testing, can measure the angle between phases, automatic identification of wiring group 0-11, for low-voltage measurement of multiple windings rectifier transformer, low-voltage side without removing the line, you can measure the ratio and 7.5 ° angular deviation.

3, applicable to a wide range of transformers, especially for Z-type transformers, rectifier transformers, grounded transformers, furnace transformers, phase-shifting transformers and other transformer measurement.

4,With high and low voltage reverse connection protection, transformer turn-to-turn short circuit protection, tap changer tap-close not in place protection, the output of the full short-circuit protection, increase the stability of the instrument.

5,After inputting the rated parameters, it can automatically measure the transformer ratio value, error value and tap changer tap position, especially for tap asymmetric tap changer, it can also accurately measure the exact position of the transformer tap changer, and it can measure the tap changer of 99 tap positions at most.

6, seven-inch high-brightness touch-colour LCD, clear display under bright light, full touch-screen operation, free switching between English and Chinese.

7, the instrument has both printout, U disk interface, can also be equipped with RS232 interface, easy to paperless office.
8, the use of cold and temperature, sealed waterproof, drop-proof shockproof multifunctional engineering plastic box, easy to field test.

9, the instrument can use android mobile phone or tablet, pay attention to wechat public number, download the special APP, through the special software to control the instrument, test data storage and uploading, easy to access.
