GFUVE ELECTRONICS is one of the leading Current Transformer and
Potential Transformer Analyzer manufacturers China, welcome to
import cheap and discount Current Transformer and Potential
Transformer Analyzer from us.
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.
Capable of performing saturation, ratio, polarity, winding
resistance, and insulation tests on current transformers, the MVCT
can also be used for testing metering and protection class
voltage/potential transformers. The MVCT provides a microprocessor
controlled variable voltage and current output along with precision
instrumentation for automatically testing single and multi-ratio
CTs and VT’s.
The PT Analyzer automatically determines all relevant Potential
transformer values and compares the results with the selected
standard. The device evaluates the Potential transformer as per the
IEC, IEEE or national/self-defined standards within seconds with
the push of a button.
GF1061 portable CT PT analyzer is mainly used for field or lab testing, it can finish the measurements (M) and protection (P) class CT, PT and TYP class CT. Adopt 7 inch touch TFT LCD, self-equipped mini type printer supporting field printing; supporting to use USB flash disk to dump data. The CT PT Analyzer is the most complete and easy-to-use testing system for protection and metering CTs according to IEEE and IEC standards.
