HZQB-C Portable Transformer Field CT PT Calibrator
Product Overview
The HZQB-C current transformer calibrator is a versatile testing instrument designed to measure the ratio difference, angle difference, admittance, and impedance of various models of current transformers (CT) and potential transformers (PT).
The instrument is equipped with a built-in micro printer, enabling immediate on-site printing of test results. Its powerful software includes comprehensive table-based functionality, and the calibrator can be connected to a computer for convenient transmission and management of test data, streamlining both field testing and laboratory analysis.
