Product Introduction
When calibrate the error of PT and CVT, the test wire will be complex, required equipment are various and too heavy to move in field. This tester with low voltage can measure the real error under high voltage. Single device can measure the error of PT and CVT.
The measurement of PT and CVT is covered the ratio of 6KV/100V,6KV/ /100V/ ,10KV/100V,10KV/ /100V/,35KV/100V,35V//100V/,110kV/100V,110kV//100V/,220kV/100V and 220kV/ /100V /. It adopts different frequency power technology, general platform technology, Voltage dummy load, internal high accuracy voltage transformer and self - boosting power supply, make it more convenient, quick and efficient. Equipped with WINCE system and colorful touch screen, visual and convenient.

Product Feature And Application
1. Without a booster, standard instrument transformer, or load case, adopt the principle of load curve extrapolation method for a voltage transformer. a single device can measure the ratio difference and angle difference under the 20%,50%,80%,100%, and 120% full load and light load of GIS, PT, and CVT.
2. A Single device can measure the error (ratio and angle difference) of PT and CV. Simultaneously measure the capacity voltage dividing ratio, the capacity of voltage dividing, middle PT ratio, middle voltage, current resistance, etc.
3. It has the function of checking polarity, change ratio, and connection.
4. Complete all the tests of wiring at one time, improve the working efficiency, avoid personal and instrument damage caused by operation errors, and ensure safety.
5. Fast test and has a large amount of information processing and large storage capacity (millions of data can be stored), it has 16 G of memory and can store millions of data sets.
6. Adopt variable frequency technology, digital processing, and strong anti-jamming capability.
7. The voltage is not more than 4KV during the test, and various protective measures to ensure personal safety and equipment safety and reliability.
8. Easy to operate.
9. Equipped with the WINCE system, and colorful touch operation, it can be operated by mouse, and the interface is visual and convenient.
10. With double USB communication ports, the internal data of the instrument can be imported into the U disk, which is greatly convenient for field data management. It can be operated by a mouse.
11. With an internal wiring diagram, make it simple and intuitive. By using control wiring on site, the test wiring can be completed correctly in one time and the preparation time can be reduced.
