For many electric equipments used in power system and enterprises, inner insulation is mostly oil-insulated. Oil dielectric strength test is one of the essential routine tests. IIJ-II Oil Dielectric Test Set is the ideal testing device for oil dielectric strength. The test sets are fully automatic.
1) Fully automatic, control by microcomputer, utilization of new I/O terminal.
2) Numbers of times of testing and idling time of stirring are set via digital setting.
3) Test results displayed and printed out automatically.
4) Strong capability of anti-interference.
5) High accuracy of testing and high capacity of anti-jamming.
6) Easy to operate, small size, light weight which operated in the open air very conveniently and convenient for maintenance
7) Can store 99 groups oil testing data which is convenient to reading and print. The testing data can keep 100 years under the condition of power off.
8) System time can go on running under power off.(the system time just for reference can not be the standard of timing)
