IAMEN JIAHUA ELECTRICAL TECHNOLOGY CO.,LTD

The device is for daily patrol inspection with high efficiency and easy operation features. Designed with two UHF signal channels, one detects the partial discharge signal; another excludes the disturbance signal like corona discharge in the air and mobile phone communication.

◆ Features

--- Portable design, convenient for daily patrol inspection, easy operation.

--- Automatically fault alarm when detecting the partial discharge inside the GIS.

--- Attached on the surface of GIS without opening the asset.

--- Good electromagnetic disturbance resistance.

--- Noise sensor improves the liability of partial discharge identification.

--- High sensitivity up to 5PC.

--- AC/DC dual power. Full charged battery lasts for 8 hours detection.
