1Short circuit current withstand testing machineOverview:
The BZKC transformer low voltage short-circuit impedance tester is mainly suitable for testing the low voltage short-circuit impedance of 35KV and above power main transformers (single-phase or three-phase) during factory, major maintenance, pre testing, and handover testing.
The BZKC transformer low voltage short-circuit impedance tester is an instrument used for measuring low voltage short-circuit impedance of 35KV and above main transformers under on-site and laboratory conditions.
The instrument is small in size, light in weight, and adopts a single-phase measurement method. Only the low-voltage side needs to be short circuited, and the high-voltage side non test phase does not need to be short circuited. After selecting a transformer connection, the short-circuit impedance of each phase can be automatically calculated after three measurements. The instrument has the function of automatically converting low current testing to rated current, which is suitable for on-site use.
This instrument can synchronously measure voltage, current, and power. Measure the frequency of the applied power supply. The instrument can automatically or manually record the applied voltage and current, and after completing the three-phase measurement, it can automatically calculate the short-circuit impedance of each phase.
Built in non power down memory, can store measurement data for a long time, and the instrument comes with a printer. Large screen LCD display, all Chinese menus and operation prompts, simple and intuitive operation.
