Scope of application
Used for low-voltage short-circuit impedance measurement of 35KV and above main transformers under field and laboratory conditions
Performance characteristics
(1) It can measure transformer short-circuit impedance, short-circuit reactance, and three-phase impedance voltage;
(2) The voltage, current, power, frequency and other parameters of each test can be displayed;
(3) Automatic frequency correction can eliminate errors caused by frequency fluctuations;
(4) Built-in non-power-off memory, which can store thousands of measurement results and save measurement data for a long time.
