KFZ Load and No-load Test Instrument is used to measure the transformer load current, load loss, short-circuit voltage, short circuit (load) losses. The machine is mainly used in the test bed with integrated for supporting the use of transformers to achieve high-precision testing of the no-load load characteristics of the transformer.
1.The transformer load and no load test instrument can measure the transformer load current, load loss, short-circuit voltage, short circuit (load) losses.
2.Harmonic test can be analyzed to 31 harmonics.
3.Support two experimental methods: three-table method and double-table method.
4.When doing no-load and load test of the three-phase transformer, the tester can automatically judge whether the wiring is correct, and display three-phase voltage and current vector map.
5.Single machine can do the following 100KVA distribution transformer full load current experiment; the load test of the distribution transformer below 250KVA can be completed under one third of the rated current.
6.All the related test results are automatically corrected.
7.320x240 large screen, high brightness LCD display and touch buttons make the operation more convenient
8.The transformer load and no-load test instrument can preset 40 sets of test sample parameters by user, and these parameters can be deleted and added at any time as needed, which is very convenient to use.
9.Come with real-time electronic clock.
10.Panel-type thermal printer
11.With power-down storage and browsing features, you can store 500 set of experimental results with computer on-line data transfer.
12.Allow external voltage transformers and current transformers to perform extended range measurement.
