Earthing and short circuit lance device

A lance device is composed by:
1) n° 1 Lance contact for conductor
2) n° 1 Earthing and short circuit lance
3) n° 1 Flag for signalling of earth connected
4) n° 1 Lance contact at ground potential
5) n° 1 Metallic extension (optional)
6) n° 1 Pole mechanical fixing
7) n° 1 Manoeuvring insulating stick

USE AND SAFETY ADVANTAGES

Earth and short circuit with lances is suited in case of:
• high short circuit current requiring heavy portable devices with big earthing conductors;
• qneed of placement of more single phase short circuit devices (in parallel);
• avoid the danger coming from strong and quick electrodynamic movement of the earthing cable during the
short circuit;
• few space in the substation, limiting the operation capability.
