Product Introduction
The UHV-107 CT/PT Volt-Ampere Characteristic Tester is engineered for automated testing of Protection-Class and Metering-Class CTs/PTs, supporting both laboratory applications and field testing.
Key Features
1、All-in-One Operation – Performs all tests (excitation curves, ratio, polarity, demag, 5%/10% error curves, secondary burden, AC withstand) without external equipment
2、Automated Analysis – Auto-detects CT/PT excitation knee-point and generates 5%/10% error curves
3、Intuitive Interface – Smart controller with large LCD graphical display for simplified operation
4、On-Site Reporting – Integrated micro-thermal printer for instant results
5、Advanced Data Management
• Stores 3,000 test sets (battery-backed retention)
• USB export to generate Word reports on standard PCs
6、Field-Optimized Design – Lightweight (≤22kg) and compact for enhanced portability
