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. In addition to the
test record header, a 20-character test description for each test in the record (10 tests per
record) can also be entered.
Internal Test Record Storage Capacity
The EZCT-2000 can store up to 140 test records in Flash EEPROM. Each test record may contain
up to 10 excitation curves, current-ratio readings, polarity and DC resistance readings. Test
records can be recalled and printed on the built-in thermal printer.
Internal Test Plan Storage Capacity
The EZCT-2000 can store up to 128 CT test plans in Flash EEPROM. A test plan defines the
excitation test voltage and current range selection, CT nameplate ratio, and CT winding
terminals (X1 to X5) for each of the tests. Up to 10 test definitions can be stored per test plan.
The use of a test plan greatly simplifies the CT testing process; the EZCT-2000 is connected to
the CT terminals and a test plan is simply selected and run. Test plans can be created on the
EZCT-2000 itself or created on a PC and downloaded to the EZCT-2000 via the unit’s built-in RS-
232C or USB interfaces.
Computer Interface
The EZCT-2000 can be used as a stand-alone unit or can be computer-controlled via the built-in
RS-232C or USB interfaces. A Windows® XP/Vista-based Current Transformer Analysis software
application is provided with each EZCT-2000. This software can be used to retrieve test records
from the EZCT-2000, create test plans, download test plans to the EZCT-2000, and can also be
used to run CT tests from the PC. Tabulated test records can be exported in Microsoft® Excel
format.
