Description
Transformer characteristic capacity tester
Functional features:
1, can accurately measure the capacity of various distribution transformers, passive measurement, convenient and accurate.
2, internal power supply, automatic generation of three-phase high-power test power supply.
3, built-in high-performance lithium-ion rechargeable battery, large capacity, fully charged can be continuously tested more than 500 sets.
4, can measure various types of transformer no-load current, no-load loss, short-circuit voltage, short-circuit loss.
5, can automatically perform waveform distortion correction, temperature correction, voltage correction (non-rated voltage no-load test), current correction (non-rated current short-circuit test), the operator only needs to input the correction index instrument according to the type of transformer can automatically calculate the corrected results, very suitable for the unit without a slightly larger capacity transformer short-circuit test conditions.
6, the voltage circuit width limit: the maximum voltage can be measured to 750V, without switching gears to ensure accuracy. It will not damage the instrument itself due to the wrong voltage gear selection.
7, capacity measurement range: 20KVA~100000KVA.
8, the remaining percentage of battery power indicator function, not a simple deficit alarm.
9, large screen, high brightness LCD display, Chinese menu and operation prompts to achieve friendly human-machine dialogue, conductive silicone touch keys to make the operation easier, longer key life.
10, the user can real-time test data through the micro printer to print out the results.
11, test result storage function, can store 200 groups of capacity test data.
