GF1061PT on-site and in laboratory Portable voltage transformer analyzer with printer
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.
The GF1061PT Transformer Analyzer measures current transformer (CT) admittance, CT ratio, CT primary-to-secondary phase angle and the voltage, current and phase angle of the service. With the 'Burden CT/PT Option', it determines the CT secondary burden capability, the regulation of the potential transformer (PT) and its secondary burden capability and provides for CT core demagnetization.
High quality CT PT analyzer for current transformer testing, AC output voltage 220V, frequency 50Hz, measurement accuracy ±0.02%, with advanced design, stable and reliable product performance, complete functions, high degree of automation and high test efficiency.
FEATURES
