RSBC-D Transformer Testing Equipment Range 0.9～10000 Automatic Variable Ratio Grouping Tester
1. Check whether the variable ratio is consistent with the nameplate value to ensure the required voltage transformation.
2. Check whether the indicated position of the voltage tap changer is correct.Transformer ratio tester test can achieve what purpose and results
3. Check the ratio of turns of each coil to determine whether there is an inter-turn short circuit in the transformer.
4. The unbalance degree of transformer ratio of three-phase transformer is measured.
5. The accuracy of transformer ratio is provided to judge whether the transformer can run in parallel.
1. The three-phase precision inverter power supply is adopted in the instrument, instead of single-phase mains power supply, which can eliminate the harmonic influence of mains voltage and make the measurement more accurate. There is no effect when the working power is generator.
2. The three-phase output voltage is adopted to improve the test speed. The Angle between phases can be measured and the transformer connection group 0-11 can be automatically identified
3. It is applicable to a wide range of transformers, especially for the measurement of z-type transformer, rectifying transformer, grounding transformer, furnace transformer, phase change transformer and balance transformer, with the most comprehensive measurement parameters.
4.The use of homemade precision three-phase inverter power, with high and low voltage reverse connection protection, transformer between turns short circuit protection, tap switch is not in place, output short circuit protection, increase the stability of the instrument.
5. After the input of rated parameters, transformer ratio, error value and tap switch tap position can be automatically measured, especially for the tap switch with asymmetric tap, the exact position of the tap switch can also be accurately measured, and the tap switch with up to 99 tap points can be measured.
6. 7-inch HD color touch screen liquid crystal, modular display, each operation step has prompt, no manual, just look at the liquid crystal prompt can complete the operation of the instrument.
7. The instrument has both print output and U disk interface, and also can be equipped with RS232 interface, which is convenient for paperless office.
