Transformer Capacity Tester -- Model KFZ
Introduction:
-
KFZ Transformer Capacity Tester can measure transformer capacity, type, no-load current, no-load loss, short circuit (load) loss, resistance voltage, etc.
-
KFZ Transformer Capacity Tester is small in volume, light in weight, in high accuracy, with steady property, easy to operation can replace the traditional testers.
-
KFZ Transformer Capacity Tester is displayed by LCD, operated by menu, with friendly interface, is the first choice for all customers.
Features:
-
KFZ Transformer Capacity Tester can accurately measure capacity of distribution transformer , convenient and accurate;
-
Automatically check if the wire was correctly connected, and display vector diagram of three phase current, voltage when test three phase transformer;
-
KFZ Transformer Capacity Tester can do loading test for substation transformer under 1000KVA; can do loading test with 1/3 of the rated current for substation transformer under 3150KVA (the device can convert to the loading losses parameters if the rated current under 1/3 of the rated current);
-
Polarity testing: single phase power transformer, three phase power transformer, CT, PT;
-
Vector group testing: three phase power transformer;
-
All the related test results are automatically corrected, such as: the waveform correction, temperature correction, non-rated voltage correction, calibration, and other non-rated current correction, so test result is more accurate.
-
Can preset 40 groups parameters of testes objects, and these parameters can be deleted or added at any time as needed, so it is easy for use.
-
With electronic clock, auto record the data, time, it is good for saving and managing the test results. With built-in printer;
-
Data (specimen setting, test results, measurement time) can be saved on power failure and can be reviewed, it can store 500 groups test results, can connect with computers to transmit data.
-
Allowance external connecting CT and PT to make extension measurement, can test the specimen with any parameters.
