The Vanguard EZCT-2000A Automated CT Test Set can perform the Current Transformer (CT) excitation test, measure the CT winding resistance and CT current-ratio automatically. All of the EZCT-2000A’s test leads can be connected to the CT output terminals, eliminating the need for lead switching during testing. Test voltage output is automatically raised and lowered by the Vanguard EZCT-2000A without any operator intervention. With up to 2000 Vac excitation test voltage available, the EZCT-2000A can easily perform excitation tests on very large CT’s.
Vanguard EZCT-2000A Automated CT Test Set features:
- Perfoms CT excitation test using the ANSI/IEEE C57.13.1, IEC 60044-1 test method
- Determines the CT current-ratio using the ANSI/IEEE C57.12.90 measurement method
- Measure the DC resistance of the CT winding under test
- Features a back-lit LCD screen that is viewable in both bright sunlight and low-light levels
- Built-in 4.5-inch wide thermal printer can print the current transformer test report and plot the excitation curves
- Test record header information can include the company name, substation name, circuit ID, manufacturer, CT serial number, operator’s name and test record comments
- Capable of storing up to 140 test records in Flash EEPROM
- Can store up to 128 CT test plans in Flash EEPROM
- Features a standard USB Flash drive interface that makes it convenient to store and transfer test records and test plans
- Can be used as a stand-alone unit or can be computer-controlled via the built-in RS-232C or USB interfaces
