GF1061PT Portable Voltage transformer tester

voltage transformer Tester

GF1061PT is the first portable device (4.8 kg) which offers highly accurate voltage transformer tests. This allows to use GF1061PT not only for electrical performance checks, but also for class verification and calibration. It performs quick tests of all kinds of inductive voltage transformers (VTs or PTs) and capacitive voltage transformers (CVTs) for both protection and metering purposes. Its lightweight design makes it ideal for on-site tests and calibration tasks in power system grids.

 

Description

As a manufacturer or testing lab you can use GF1061PT in your production facilities and test/development labs. it can finish the measurements (M) and protection (P) class PT. Adopt 7 inch touch TFT color LCD, self-equipped mini type printer supporting field printing; supporting to use USB flash disk to dump data. The GF1061PT portable PT tester is the most complete and easy-to-use testing system for PTs according to IEEE and IEC standards.

Features

  • Tests of various types of measurement and protection VTs and CVTs
  • The use of advanced power technology, the test knee point reaches up to 80kV
  • No external other auxiliary equipment, stand-alone to complete all test items
  • Tests such as ratio, phase, polarity, capacitive ratio
  • PT test, easy to test, all the tests are using the same wire connection except the load test
  • It carries with thermal printer, printing test results on site
  • Parameters such as knee point current and voltage
  • Parameters such as 10% error curve, 5% error curve
  • With battery, working one week.
  • The device can store 10000 groups of test data which would not be lost if the device is power off.
  • The data can be displayed and analyzed after the test, or transferred to PC through USB disk and produce a Word or PDF file report
  • Portability: weight 4.8kg, the best light pt analyzer
