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 excitationknee-pointand generates 5%/10%error curves
3、Intuitive Interface– Smart controller withlarge LCD graphical displayfor simplified operation
4、On-Site Reporting– Integratedmicro-thermal printerfor instant results
5、Advanced Data Management
• Stores 3,000 test sets (battery-backed retention)
• USB export togenerate Word reportson standard PCs
6、Field-Optimized Design– Lightweight (≤22kg) and compact for enhanced portability
