Test Record Header Information
The 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 can also be
entered.
Internal Test Record Storage Capacity
The EZCT S2 can store up to 140 test records in Flash EEPROM. Each test record may contain up
to 10 excitation curves, current-ratio readings, and winding polarity readings. Test records can
be recalled and printed on the built-in thermal printer.
Internal Test Plan Storage Capacity
The EZCT S2 can store up to 128 CT test plans in Flash EEPROM. A test plan defines the
excitation test voltage and current selection, CT nameplate ratio, and CT winding terminal
connection instructions for each test. Up to 10 test definitions can be stored in each test plan.
The use of a test plan greatly simplifies the CT testing process since it also provides instructions
for making the proper CT cable connections. Test plans can be created on the EZCT S2 itself or
created on a PC and downloaded to the EZCT S2 via the unit’s built-in RS-232C or USB port.
Computer Interface
The EZCT S2 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 S2. This software can be used to retrieve test records
from the EZCT S2, create test plans, download test plans to the EZCT S2, and can also be used to
run CT tests from the PC. Tabulated test records can be exported in Microsoft® Excel format.
