Low voltage short circuit impedance measurement is the routine test item of transformer, SXDZ-II Low Voltage Short Circuit Impedance Analyzer is used for 35kV and above main transformers. It’s both suitable for on site and laboratory test.
♦ Small size, light weight.
♦ Voltage and current sampling synchronously and signal digital signal processing technology, measurement data is accurate.
♦ Adapts single phase measurement. When the transformer connection is selection, every phase short circuit can be calculated well automatically after three times measurements.
♦ Low current measurement can be calculated to rated current automatically, suitable for on-site test.
♦ Voltage, current, power can be measured synchronously. The frequency of apply power supply is also can be measured.
♦ Built in printer. No power failure memory for test data long storage.
♦ LCD screen, friendly interface, easy to operate. The data can be read clearly even in direct sunlight.
