Description

General

With many years’ experience in designing, manufacturing, making shielding rooms, PD detectors and partial discharge free test equipment, we provide clients with partial discharge shielding rooms for high-voltage equipment and insulation products. The system can ensure the noise level less than 1.0 pC after installing the Partial Discharge Detection system. It is in compliance with National Standard GB12190-90. We can design, manufacturer and construct the room according to the specific need.

Shielding Result

The following shielding results can be achieved by the shielding room at the range between 10 kHz and dozens of MHz high frequencies.

 • Magnetic field: > 60 dB between 10 and 100 kHz

    > 60 dB between 100 kHz and 1 GHz

• Electric field:  > 60 dB between 1 kHz and 1 GHz

• Plane wave: 80 dB between 50 MHz and 1 GHz

• Insulation index of insulation layer: > 1000 MΩ

• Background noise level of the whole system: ≤ 1.0 pC
