High-Voltage Cable Tester
1. Product Name and Model:
Product Name: High-Voltage Cable Tester
Product Model: CT03H
II. Main Principle:
The high-voltage cable testing system is based on Ohm's Law as its fundamental theory, using the characteristic behaviors of conventional components—such as resistors, capacitors, and diodes—as test model representatives. Guided by the objectives of efficiency and accuracy, the system ensures safety through rigorously defined high-voltage safety testing conditions. Leveraging the powerful capabilities of computer visualization and high-speed data processing, it delivers a highly efficient, integrated hardware-and-software testing solution.

V. Technical Features and Advantages:
1. Simplified Chinese WINDOWS software interface, easy to use.
2. Quickly connect or replace the cable under test using adapter cables or an adapter box, making it suitable for testing multiple cable types in large volumes.
3. Equipped with a self-learning function, it quickly masters unknown wiring configurations as well as the actual impedance and capacitance values, making editing effortless and eliminating the hassle of manually entering wiring relationships.
4. Equipped with auxiliary assembly functionality, this system uses rapid on-off scanning to quickly locate the test points contacted by the probe and accurately display the wire harness assembly position. This significantly boosts assembly speed while minimizing the need for wire marking procedures.
5. Features a system verification function: It checks and calibrates the signal source, measures system capacitance and resistance, and eliminates the influence of distributed parameters.
6. Features a self-check function: Automatically tests the system's internal signal sources, A/D converters, D/A converters, and channel boards to ensure reliable machine operation and accurate test results.
7. Fast on-off testing at 500 points per second, quickly displaying the test connection status and automatically identifying and highlighting error points.
8. Automated grouping, arrangement, and short-circuit testing identify all potential short-circuit errors (such as misconnections or multiple connections).
9. The program controls the automated testing process, allowing multiple inspections of product cables at any time, which facilitates quality management and significantly boosts work efficiency.
10. The four-wire test method for precise resistance measurement detects even minute changes in contact resistance, helping to identify potential quality issues such as poor contact, broken strands in wire cores, and missing connections in parallel wiring.
11. Freely adjust high-voltage (insulation/breakdown) test parameters to meet the testing requirements of different cables and wire cores, enhancing test efficiency while ensuring measurement accuracy.
12. Quickly perform insulation/breakdown tests between any two core wires, identifying all potential defects such as poor insulation or overcurrent-related breakdown issues.
13. Boost Delay: The delay time during which the voltage steadily rises from 0V to the set output level, eliminating the influence of distributed parameters and ensuring compatibility with cables that have significant distributed characteristics (such as shielded cables, extra-long cables, and twisted-pair cables).
14. Pressure-Induced Delay: Ensure high voltage is applied to the cable under test and maintained at that level, continuously monitoring the leakage current while recording the maximum value observed.
15. Voltage Drop Delay: The delay time during which the output voltage drops from the set level to 0V, eliminating distributed parameters, ensuring operational safety, and enabling high-current testing.
16. Test results can be statistically analyzed and then stored or printed.
17. Password protection provides multi-level access permissions for operators and engineers, facilitating operational management, quality control, and safety management.
