Vanguard’s EZCT-2000A Offers CT Testing You Can Rely On

The Vanguard EZCT-2000A microprocessor-based Current Transformer Test Set can perform the Current Transformer (CT) excitation test, measure the CT winding resistance and CT current-ratio automatically. All of the  Vanguard 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 Vanguard EZCT-2000A  can easily perform excitation tests on very large CT’s.Vanguard EZCT-2000A microprocessor-based Current Transformer Test Set

Excitation Test
The CT excitation test is performed using the ANSI/IEEE C57.13.1, IEC 60044-1 test method.

CT Ratio and Polarity Test
The  Vanguard EZCT-2000A  determines the CT current-ratio using the ANSI/IEEE C57.12.90 measurement method.

CT Winding Resistance Test
The  Vanguard EZCT-2000A  can also measure the DC resistance of the CT winding under test.

User Interface and Display
The Vanguard EZCT-2000A features a back-lit LCD screen that is viewable in both bright sunlight and low-light levels.

Thermal Printer
A built-in 4.5-inch wide thermal printer can print the current transformer test report and plot the excitation curves.

Test Record Header Information
Test record header information can include the company name, substation name, circuit ID, manufacturer, CT serial number, operator’s name and test record comments.

Internal Test Record Storage Capacity
The  Vanguard EZCT-2000A  can store up to 140 test records in Flash EEPROM.

Internal Test Plan Storage Capacity
The  Vanguard EZCT-2000A  can store up to 128 CT test plans in Flash EEPROM.

External Data Storage
The  Vanguard EZCT-2000A  features a standard USB Flash drive interface that makes it convenient to store and transfer test records and test plans.

Computer Interface
