Transformer Dielectric Loss Tester
Advanced high voltage dielectric loss tan delta tester for precise electrical equipment testing and analysis.
Product Overview
The SXJS-Dielectric Loss Tester is a fully automatic instrument designed for measuring dielectric loss (tgδ) and capacitance (Cx) of electrical equipment. Ideal for testing transformers, insulating bushings, capacitors, CT/PT, MOA, and various electrical components.
Key Features
- Precise Anti-Interference: Frequency conversion technology ensures accurate measurements even under 200% interference conditions
- Low Resistance Design: Full-range input resistance <2Ω eliminates auxiliary capacitance effects
- Multi-Level Safety Protection: Comprehensive 3-level protection system with HV cut-off, LV overvoltage protection, grounding protection, and overcurrent protection
- Anti-Misoperation Design: Dual power switches, real-time monitoring, and separated HV/LV terminals with safety alarms
- Practical Functions: Auto-stabilization for large-capacity samples, insulated HV cable, and robust construction
- Multi-Mode Adaptability: Supports positive/negative connection, internal/external standard capacitance/HV with built-in test modes
- Convenient Operation: Large backlit LCD, English menu, auto sample identification, built-in printer, and 255 data storage
- Power Supply Compatibility: Auto-identifies 50/60Hz, supports generators, and works with frequency fluctuations
- CVT-Specific Testing: Self-excitation testing for C1/C2 capacitance and dielectric loss measurements
- Communication Integration: RS232 port for PC control, data processing, and system integration
