HV Shielded Test Room
Description
The HV partial discharge hall is mainly used for power transformer, HV inductor, arrester, HV switch, HV XLPE cable and so on, the shielded room is used for avoiding electromagnetic interference which can affect partial discharge test.
2. Technical Parameters
|
Rated Voltage (kV) |
±100-2000 (and above) |
|
Exterior Dimension (m) |
60*40*30(L*W*H)(bigger size is available) |
|
Grounding Resistor |
Requirement<1.0Ω |
|
Insulating Resistance |
≤10KΩ(measured after completing shielding room, insulating ground mainly used fro HV cable partial discharge hall, because there is a high requirement for partial discharge of HV cable with large capacity) |
