Product Description

Portable Multi-function 220kV CVT PT On Site Calibrator GDPT-103C


Product Description

GDPT-103C CVT On-site Calibrator is designed for analyzing and Calibrate CVT for on-site test.


Features

 

1. No need for boosting source, standard transformer, load box, and the principle of extrapolation of voltage transformer load curve, single instrument can make on-site test GIS electromagnetic voltage transformer (PT) and capacitive voltage transformer (CVT) 20%, 50%, 80%, 100%, 120% of the ratio and angular difference at full load and light load. The test results fully meet the national transformer verification procedures.
2.  The measurement of GIS electromagnetic voltage transformer (PT) and capacitive voltage transformer (CVT) error (ratio difference, angular difference) can be completed by a single tester. At the same time, it can measure the capacitance division ratio, the voltage dividing capacitance, the intermediate PT ratio, the intermediate voltage, and the DC resistance of the CVT.
3.  With polarity, ratio, wiring check function.
4.  Complete all tests at one time to improve work efficiency, avoid damage to people and instruments caused by operational errors, and ensure safety.
5.  It has the characteristics of fast test speed, large amount of processing information and large storage capacity (can store millions of data). The memory is 16G and can store millions of data.
6.  The tester adopts frequency conversion technology and digital processing, and has strong anti-interference ability on site.
7.  The maximum voltage during the test process does not exceed 4KV, and various protective measures are taken to ensure personal safety and equipment safety and reliability.
8.  The test process is simple to operate.
9.  The instrument adopts WINCE system, humanized color touch screen operation, and can also operate the instrument with mouse. The man-machine interface is intuitive and convenient.
10.  The instrument has dual USB communication port, which can import the internal data of the instrument into the U disk, which is very convenient for on-site data management. The instrument can also be operated using the mouse.
11.  The wiring diagram inside the instrument is simple and intuitive. The use of the control wiring on site can ensure the correct completion of the test wiring at one time and reduce the preparation time.
