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.
±100-2000 (and above)
60*40*30(L*W*H)(bigger size is available)
≤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)
≤2.0 PC(Shielding hall partial discharge value is below 2 PC if equipment can reach below 2.0PC)
10kHZ attenuation 60dB linearity rise to 100KHZ, attenuation 100dB
From 1kHZ to 100kHZ attenuation 100dB
