Description
Zinc oxide arrester live tester is a special instrument which is used to test various electrical parameters of lightning arrester in the field and laboratory. It is widely used in the on-line monitoring (live test) of zinc oxide arrester and in the testing of laboratory (power failure overhaul). It meets the power industry standard of the People's Republic of China "DL474.5-92 Field Insulation Test Implementation Guidelines - Lightning Arrester Test" of the strategy. The instrument adopts advanced technology such as sampling and control by microcomputer. It can measure the total current third harmonic resistive current peak value of resistive current capacitive current and active power of zinc oxide arrester under power frequency voltage. And display voltage current waveform and printout test data. Large screen LCD display Chinese menu prompt operation so that the human-computer exchange function is stronger while providing on-site waveform display. This instrument has the characteristics of simple wiring high accuracy and reliability. The instrument is small in size and light in weight and adopts integrated design for easy carrying and field operation.
