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 tested equipment, 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 flow 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: In volt-ampere characteristic test, the maximum output voltage of the standalone instrument is 1000V, with an external booster (optional) the voltage can be increased to 2500V; the maximum current for ratio test and primary current flow is 1000A, the instrument output capacity is 5kVA, and it can perform volt-ampere characteristic tests on 500kV class 1A current transformers. 
4. User-friendly interface: Large 320*240 dot matrix Chinese character graphic interface with clear and beautiful graphics; uses a high-performance rotary mouse for simple and convenient operation with long lifespan; comes with a micro printer for immediate printing of test data and curves. 
5. Large data storage: The instrument has built-in memory, and test data from all functional modules can be saved and retained even when power is off. After on-site testing, results can be viewed and printed indoors.
6. U-disk transfer: Supports transferring test data via U-disk, which can be read by 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 complete test reports, facilitating centralized data management. 
8. Multiple power supply modes: The instrument supports adaptive power supply of AC220V or AC380V. 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.
