The PT excitation characteristic tester is an enhanced excitation characteristic tester launched by our company. The instrument adopts good high-speed microprocessor technology, with stronger functions, superior performance, and more convenient use. It has the characteristics of high work reliability, easy operation, high testing accuracy, and small and lightweight. Currently at a high level domestically.
 

1. Automatically collect, measure, display, store, and print measurement parameters and excitation characteristic curves (voltage, current, power, frequency, equipment number, time, etc.).
2. A large range, capable of automatically and manually measuring the excitation data and characteristic curves of most transformers.
3. Built in large capacity memory, capable of storing test data and uploading it to a PC via a standard industrial communication interface (RS232). Utilizing our company's developed random software, data download, automatic generation, and editing of typical test reports can be achieved, facilitating technical management and archiving. 
4. It has complete overvoltage and overcurrent protection functions, among which the overcurrent and overvoltage protection values are automatically adjusted according to the setting of test parameters, which is both simple and can ensure the safety of the tested equipment.
5. Can also be used for volt ampere characteristic testing of voltage (current) transformers and arc suppression coils.
6. Comes with a large screen graphic LCD, Chinese menu interface, cursor prompt operation, simple and convenient; Real time display of test data and curves, automatic scaling of curve coordinates, and clearer image reading. 
7. Equipped with a micro printer, it can print test reports in real-time.
