GF1061PT Portable Voltage transformer tester

voltage transformer Tester

GF1061PT voltage transformer tester is the first portable test equipment (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. As a manufacturer or testing lab you can use GF1061PT in your production facilities and test/development labs.
