General Information:
EPCP-III is portable analyzer designed for analyzing current transformers and voltage transformers of protection or measurement use, which is suitable for laboratory and on-site test.
Feature:
-Support detection of CT and PT
-No need to connect other auxiliary equipment, can complete all test items, and complete the excitation and transformation ratio polarity test at the same time in one test.
-Fast printer, which can print test results directly on site.
-Easy to operate, with intelligent prompts, making it easier for users to operate.
-Large screen LCD, graphical display interface. (Touch screen is option)
-Automatically give CT/PT (excitation) inflection point value according to regulations.
-Automatically give 5% and 10% error curves.
-3000 sets of test data can be saved, which will not be lost after power failure.
-Support U disk transfer data, can be read through a standard PC, and generate WORD report.
-Small and light weight ≤22kg, very conducive to field testing.
