Determines all relevant current transformer values and compare result within seconds with push of a button. IEC or IEEE. Fast and economical on-site testing and calibration. For Manufacturer of current,hv transformer and switchgear during dvpt and pro Ⅰ Introduction HVCT-1000P Series CT Analyzer automatically determines all relevant current transformer values and compares the results with the selected standard. The device evaluates the current transformer as per the IEC or IEEE standard within seconds with the push of a button. It facilitates fast and economical on-site testing and calibration of metering and protection current transformers. Manufacturers of current transformers, high voltage transformers and switchgear also use the CT Analyzer for tests during development and production. Ⅱ Features 1. Wide range of measurements: (1) CT: • CT ratio and phase-angle accuracy • CT accuracy for different burdens • CT winding resistance • CT excitation characteristics • CT inductance (saturated and unsaturated) • ALF and FS (direct and indirect) • Burden impedance • CT residual magnetism (2) PT: • PT excitation and saturation • Burden impedance • Winding resistance Saturated and non-saturated inductance • PT polarity
