1.1 Introduction
GDKF Transformer Load Tester and Noload Loss Test Instrumentis a full automatic tester for load characteristic testing of power
transformer. It is small, light and easy to use. Large size LCD
used to display the test result. All the test result can be saved
in the tester and printed by the micro-printer internal the tester.
1.2 Function
1) RMS value measurement for , and
2) Compute the RMS value for , and based on average value of the
three voltage
3) Current measurement for , and
4) No load losses and Load losses measurement
5) Excitation current in no load condition
6) Impedance voltage
7) Impedance in short current
8) Test range from 30KVA to 2.5MVA in single unit.
9) Add PT and CT in separate for the tester will extend its test
range.
1.3 Technique Index
