HYDR Transformer Qasir Ċirkwit Impedenza Tester

A transformer short circuit impedance tester is used to measure the short circuit impedance for main transformers of Level 35KV and above under site and laboratory conditions. The tester is exquisitely designed with superior performance. The state-of-the-art single-chip microcomputer testing technology and digital signal processing technology have been adopted for its internal design, and the data measured by it are accurate; while a 7-inch touch color LCD screen has been used for its external design, displaying the operation menu in Chinese with more convenient touch operation. Meanwhile, it is equipped with a thermal printer and has the function of storage, which is convenient for data printing and storage. Thus, the data to be exported can be transferred to the computer via USB. Moreover, the tester is small in volume and easy to use and carry at the site. Single-phase and three-phase tests can be conducted after inputting parameters into the tester and the percentage error of the transformer impedance will be calculated automatically with intuitive test results. It is an instrument to rapidly test whether the transformer winding is deformed or not at the site.

1. Provvista ta 'enerġija ta' vultaġġ baxx AC 220V hija adottata għat-tester li japplika l-kurrent għall-koljaturi AB, BC, u CA ta 'transformers ta' fażi waħda u tliet fażijiet f'modi manwali u awtomatiċi. It-tester jista 'jkejjel mhux biss l-iżball perċentwali tal-impedenza taċ-ċirkwit qasir tat-transformer meta mqabbel mal-impedenza tal-pjanċa tal-isem, iżda wkoll l-impedenza tat-transformer, ir-reżistenza tar-reattanza, u l-inductance, li huwa konvenjenti għall-utenti biex iqabblu d-dejta b'riżultati tat-test intuwittivi.

2. Kemm it-test b'fażi waħda kif ukoll it-testijiet bi tliet fażijiet jistgħu jsiru mit-tester; Kemm l-ittestjar manwali kif ukoll l-ittestjar awtomatiku huma permessi.

3. It-test bi tliet fażijiet jista 'jitlesta awtomatikament mingħajr linji tat-test maqluba minħabba l-wajers ta' darba tiegħu;
