The transformer comprehensive tester HZTC-415 is a new generation of revolutionary CT and PT testing instruments launched to the market after extensive market research, rigorous professional testing, and certification by authoritative departments. Due to its large output capacity and comprehensive functions, this product is very suitable for on-site testing and calibration of various specifications of CT and PT.
II.Product Features:
1. Fully automatic tester
Simply set the maximum output voltage and maximum output current, and the instrument will automatically increase voltage or current from zero for various tests. During the test, it automatically records test data, plots the volt-ampere characteristic curve, 10% and 5% error curves, and automatically calculates the inflection point value. This eliminates tedious steps such as manual voltage adjustment, manual recording and sorting, and curve drawing, greatly improving testing efficiency. Test results can be stored in the instrument, printed on-site or later, or transferred to a computer via USB drive for processing and printing. The operation is fast, simple, convenient, and easy to master.
2. Comprehensive functions
The functions of the device are as follows:
CT test: Volt-ampere characteristic curve PT test: Volt-ampere characteristic curve
Automatic calculation of curve inflection point
5% and 10% error curves
Ratio, polarity Ratio, polarity
Ratio error, phase error measurement Ratio error, phase error measurement
Secondary loop load test
Secondary winding AC withstand voltage
Secondary DC resistance test
Primary current flow test
3. Output hold: Has voltage boost hold function for metering detection and secondary AC withstand voltage test. Has current boost hold function for secondary loop inspection.
4. True RMS sampling: All voltage and current signals are sampled as true RMS values. Please use a true RMS meter for calibration.
5. Single power supply, easy operation: Only requires a single input power supply, AC220V, abandoning the outdated method of some manufacturers that require 380V power supply to meet technical requirements.
6. USB drive storage: Test data can be transferred to a PC via USB drive for processing, display, printing, storage of data and curve reports, greatly facilitating report organization for users.
7. Date and clock: The instrument comes with a system time. During tests, the device automatically records the test time for easy storage and review of test records.
8. Non-contact testing, high safety: Fully computerized device. After setting is completed, no manual contact is needed, and the instrument performs tests automatically. This keeps test personnel away from high-voltage circuits, ensuring their safety.
9. Large output capacity: The single unit has high output power, with AC voltage output up to 2000V, current output up to 25A for short periods, and maximum current of 600A.
10. Built-in large 8-inch color touch LCD, fully Chinese graphical interface: The screen resolution is as high as 800*600, with high clarity. Full-color touch operation is leading domestically, with a dreamlike interface background. During tests, the volt-ampere curve and test records are directly displayed, making it intuitive and convenient. The panel comes with a printer that can print curves and test data at any time.
11. Touch screen operation: Uses our company's unique touch technology for operation. Completely eliminates conventional controls such as panel buttons, switches, and control knobs. The operation is simple and convenient, with a long service life.
12. Large-capacity data storage: Each function test can store 50 sets of test data. Data will never be lost after power failure. After testing, data can be recalled for printing or uploaded to a computer for storage and printing. The instrument also has a USB drive data storage function, allowing on-site test data to be saved to a USB drive for unlimited storage of on-site test records.
