1. Voltage Range and Frequency Compatibility
Match the tester's maximum voltage (e.g., 35kV or 50kV) to your typical cable ratings.
Ensure frequency adjustment covers 0.1Hz–0.01Hz for diverse applications.
2. Portability and Field Readiness
Prioritize compact designs (under 15kg) with built-in handles.
Check battery life for on-site testing without external power
3. Compliance with Safety Standards
Verify certifications such as IEC 60060 for high-voltage testing safety.
4. Data Logging and Reporting Features
Look for testers with automated report generation to streamline audit documentation.
5. After-Sales Support and Training
Choose suppliers offering technical training workshops and responsive customer service.
