HZCT-IV Power Frequency CT PT Analyser
Products Description
Main Technical Features
1. Fully Automated Testing
Set maximum output voltage/current, and the instrument automatically ramps up for testing.
Records test data, V-I curves, 5%/10% error curves, and auto-calculates inflection points.
Eliminates manual voltage regulation, data recording, and curve tracing.
Supports on-site printing, USB data export, and computer-based report generation.
2. Comprehensive Testing Functions
CT Testing:
V-I characteristic curve, inflection point calculation, 5%/10% error curves.
Ratio, polarity, differential/angular error measurement.
Secondary circuit load testing, AC/DC winding resistance, and current flow test.
PT Testing:
V-I characteristic curve, inflection point calculation, 5%/10% error curves.
Ratio, polarity, differential/angular error measurement.
Secondary circuit load testing and AC/DC winding resistance.
3. Output Holding Function
Maintains boosted voltage for secondary loop inspection and AC withstand voltage tests.
4. True RMS Sampling
All voltage/current measurements use true RMS sampling for accuracy.
5. Single-Power Operation
Powered by standard AC220V-no 380V input required.
6. USB Data Export
Save test data via USB for PC processing, display, and reporting.
7. Integrated Date/Time Logging
Auto-records test timestamps for traceability.
8. Non-Contact Testing
Fully automated operation ensures operator safety by eliminating high-voltage exposure.
9. High-Capacity Output
Voltage: Up to 2000V AC
Current: 25A (short-term), 600A (max).
10. 8-Inch Color Touchscreen
800×600 HD resolution with intuitive UI.
Real-time V-I curve display and on-board printing.
11. Touchscreen Operation
Proprietary touch technology replaces physical buttons for durability and ease of use.
12. Expansive Data Storage
Stores 50 test sets per function (non-volatile memory).
Unlimited storage via USB export for field data.
