HZ-2000F Transformer Tan Delta Dielectric Loss Test Machine
The HZ-2000F transformer tan delta dielectric loss tester adopts variable frequency power supply technology, utilizing a microcontroller and modern electronic technology for automatic frequency conversion, analog-to-digital conversion, and data calculation.
The power supply uses a high-power switching power supply, outputting pure sine waves at 45 Hz and 55 Hz with automatic voltage boosting up to a maximum of 10 kV. It automatically filters out 50 Hz interference, making it suitable for on-site testing in substations and other environments with high electromagnetic interference.
Feature
Digital Filtering: Fourier transform – high precision, auto measurement
Frequency Conversion: Eliminates 50Hz interference – reliable in strong EMI
Touchscreen: Full-touch large LCD – graphical interface, no training needed
Data Storage: Calendar chip + large memory – save, review, print anytime
Data Management: USB export – PC software for viewing/management
Easy Operation: Microprocessor-controlled – auto measurement
Integrated Design: Built-in standard capacitor + HV supply – reduces field wiring
High Accuracy: Meets oil dielectric loss requirements – add oil cup and test leads
Reverse Wiring Shielding: 220kV CVT bus grounded – 10kV reverse wiring on C11 (no wire removal)
AC Withstand: PT/CT secondary side and 400V low-voltage system withstand testing
