8、high voltage protection: test short circuit, breakdown or high voltage current fluctuation, can cut off the output by short circuit.
9、low voltage protection: misconnection 380V, power supply fluctuation or sudden power failure, start protection, will not cause overvoltage.
10、grounding protection: the instrument grounding is bad so that the shell with dangerous voltage, start grounding protection.
11、C V T: high voltage and current, low voltage and current four protection limits, will not damage the equipment; Incorrect menu selection does not output excitation voltage. There is no 10kV high voltage output during CVT measurement.
12、anti "capacity rise" : when measuring large capacity test products will appear voltage rise "capacity rise" effect, the instrument can automatically track the output voltage, keep the test voltage constant.
13、seismic performance: the instrument adopts unique seismic design, can withstand strong long-distance transportation vibration, turbulence without damage.
14、high voltage cable: high voltage insulated wire, can be used to mop the floor.
15、 technical breakthrough, powerful function, with external standard capacitor interface, automatic tracking of external test power frequency 40Hz~70Hz, support frequency power supply and series resonant power supply to do large capacity high voltage dielectric loss test.
16、 with circuit contact bad discharge prompt function, to facilitate the identification of wiring is reliable.
17、with CVT self-excitation method measurement function, C1/C2 can be measured at the same time, automatic compensation busbar grounding and standard capacitor partial voltage influence, no need to change the line and external any accessories, and high voltage connection line can mop the floor.
18、with reverse wiring low voltage shielding function, in the 220kVCVT busbar grounding case, the C11 can be carried out without stripping 10kV reverse wiring dielectric loss measurement, and can be a connection at the same time to the main and slave two capacitance measurement.
