portable ac resonant test system for 35kV cable, GIS test
Overview:
The Resonant test set is to change the system inductance and test frequency to make circuit in resonant condition. Its operation interface is as below FIG 1. The adoption of variable frequency resonant technology reduces the capacity of power source and the weight of equipment, which facilitates on-site test.
II. Feature:
1. Device with over-voltage,over-current, zero startup, system detuning,high voltage flashover fault,ect protection function.the over-voltage over-current protection value can be set according to the needs of user.flashover protection movement when the test object flashover, and mark down flashover voltage value, for test analyzed.
2.The whole device ,the largest piece very light weight not more than 40kg and convenient for field use.
3.Device has four working mode, user-friendly according to the site condition flexible choice, improve test speed.working mode as automatic mode,manual mode,automatic tune mode and manual boost mode.
4.Can store and print data,nonlocal print data, the serial number of the stored data is number, easy to help users digital identification and searching.
5.Frequency starting point can be set arbitrarily within prescribed scope when the device automatic frequency sweep.Sweep frequency direction can choose to up or down,, meanwhile color LCD big screen display scanning resonance boost and timing curve, be convenient for the user intuitive understanding whether find resonant point.
6.Adopted DSP platform technology, according to user needs ,can conveniently increase or decrease function and upgrade, but also makes the man-computer exchange interface humanized.
