1. Measurement of no-load loss: The instrument displays three-phase voltage, three-phase current, and three-phase power. The instrument displays the distortion rate of the applied power waveform and automatically calculates the no-load current of the transformer. It is converted to the rated voltage and waveform distortion is performed. Corrected no-load loss.
2. Measurement of load loss: TPBZC transformer loss parameter tester can display three-phase voltage, three-phase current, and three-phase power, and automatically calculate the transformer's impedance voltage percentage and convert it to the rated temperature and load loss under rated current.
3, three-phase transformer single-phase measurement: can be used to check the transformer single-phase defects or for the scene without three-phase electricity situation. The instrument can record the data of three single-phase measurements, and calculate the no-load current, no-load loss, impedance voltage and load loss of the transformer according to the different connections of the transformer.
4, loss of inquiry function: the instrument contains the national standard 30KVA-2500KVA amorphous alloy, S11, S9, S7, the percentage of no-load current, no-load loss, impedance voltage percentage, load loss, according to the type of transformer, The capacity of the transformer is queried.
5, in the instrument allows the measurement range can be measured directly, beyond the measurement range can be external voltage, current transformer, the instrument can set the ratio of external voltage and current transformer, directly display the value of the applied voltage and current.
6. The large-screen liquid crystal display of the instrument can display three-phase voltage, three-phase current, three-phase power, three-phase average voltage, average current, three-phase total power and related data on the same screen. Instrument Chinese menu, Chinese tips, easy to operate.
7. The instrument is equipped with a 232 interface, which can be used to communicate with the computer through the data line, and provide background data management software running on the computer.
8, the instrument comes with a printer, print display data, built-in memory, power loss is not lost, the instrument can store 20 sets of data.
9, permanent calendar, clock function, time calibration.
