The KINGSINE KT220 is an ultra-portable, battery-operated handheld CT/PT analyzer designed for on-site testing and commissioning of protection and metering current and potential transformers.
High Accuracy: Typical ratio accuracy of 0.02% (0.05% guaranteed).
Ultra-Lightweight & Portable: Main unit weighs <3.5 kg (7.7 lbs) with dimensions of 288 × 185 × 95 mm, featuring an integrated 10.1-inch Full HD touchscreen.
Power Supply: Equipped with a built-in replaceable 10.8V / 4500mAh lithium battery supporting USB Type-C PD 3.0 fast charging, alongside standard AC power input (100–264 Vac).
Standards Compliance: Conforms to IEEE C57.13, ANSI 30/45, IEC 60044-1/6, and IEC 61869-2 standards.
CT Ratio & Phase Angle: Measures ratio (up to 10,000:1), polarity, and phase displacement under nominal/operational burden.
Excitation & Saturation: Low-voltage variable frequency method (max 120 Vac output) capable of measuring knee-point voltages from 1 V up to 30 kV safely.
Winding Resistance & Burden: Secondary winding resistance range from 0.1 to 300 Ω and secondary burden impedance measurement.
Residual Magnetism & Demagnetization: Analyzes remanence conditions to aid grid failure investigations and performs automatic demagnetization after testing.
“Nameplate Guessing” Function: Automatically determines parameters (ratio, class, knee point, winding resistance) for unlabeled or unknown CTs.
Data Management: Direct export of test reports to Microsoft Word and full remote PC control via RJ45 Ethernet interface.
