Product Features


1. Safe and convenient: The instrument has a high degree of automation, automatically completing set tests and providing test results and curves. Test personnel do not need to contact the device under test, staying away from high-voltage circuits to ensure personal safety.

2. Comprehensive functions: The instrument integrates CT volt-ampere characteristic test, CT ratio polarity test, CT polarity test, CT primary current injection test, CT AC withstand voltage test, PT volt-ampere characteristic test, PT ratio polarity test, PT polarity test, and PT AC withstand voltage test. It automatically calculates knee point voltage and current values, ratio difference values, and 5% or 10% error curve values, and saves and prints test records and dates in real time for user convenience in organizing test reports.

3. Large output capacity: For volt-ampere characteristic tests, the standalone maximum output voltage is 1000V; with an external booster (optional), the maximum voltage can be raised to 2500V. For ratio tests and primary current injection, the maximum current is 1000A. The instrument has an output capacity of 5kVA and can perform volt-ampere characteristic tests on 500kV class 1A current transformers. 

4. User-friendly interface: Large 320*240 dot matrix Chinese character graphical interface with clear and beautiful graphics; uses a high-performance rotary mouse for simple, convenient operation and long service life; built-in micro printer for immediate printing of test data and curves. 

5. Large data storage capacity: The instrument has built-in memory, and test data from all functional modules can be saved without loss upon power failure. After on-site testing, results can be viewed and printed indoors.

6. U-disk transfer: Supports U-disk data transfer for test data, which can be read via PC for quick and convenient operation.

7. Powerful PC software: The PC application software is powerful and easy to operate, enabling data analysis, saving, printing, and generation of comprehensive test reports, facilitating centralized data management. 

8. Multiple power supply modes: The instrument supports AC220V or AC380V adaptive power supply. When the AC power input terminals are connected to AC220V, the AC voltage output is 0-600V; when connected to AC380V, the AC voltage output is 0-1000V, allowing users to choose according to actual needs.
