Product introduction
NAELECTRIC high-voltage switch dynamic characteristics tester (without power supply) is a newly researched and developed special instruments, as to adapt the needs of high-voltage switching operation characteristics developed. With the single machine as core to sample, to process and output. NAELECTRIC high-voltage switch dynamic characteristics tester mainly adopted all English characters tips to man-machine dialogue operation, character display and print out the results, with intelligent, multi-function, accurate data, strong anti-jamming, simple operation, small in size, light in weight, beautiful appearance, etc., Suitable for a variety of indoor & outdoor, less oil & more oil switches, vacuum switches, sulfur hexafluoride switch dynamic characteristics testing.
