CT/PT Analyzer

Key Features

• Low testing time — one-time connection runs an automatic schedule covering all basic CT winding and core tests in minutes
• Highest accuracy — up to 0.02% for turns ratio and winding resistance, measuring Class 0.1 metering CTs
• High interference rejection for reliable testing inside live 220 kV, 400 kV and 765 kV charged switchyards
• Automatic pass/fail — compares results to the nameplate per IEC standards and flags failed parameters in red
• 30 cm TFT colour touch screen driven by advanced algorithms and state-of-the-art noise reduction
• Portable & field ready — ≤ 10 kg rugged case with quick one-click Word report generation
• Full CT suite: excitation curve, turns ratio, ratio & phase error, polarity, coil resistance, secondary burden, error-line curve, saturation hysteresis loop and automatic demagnetization
• Full PT/VT suite: turns ratio & phase angle error, polarity, secondary burden and winding resistance (CVT module optional)
