Earthing system - Schneider Electric
Earthing systemHow to choose the right system Earthing arrangement?Application noteTechnical collection In order to ensure protection of persons and continuity of operation, the conductive wires and live parts of an electrical installation are "insulated" from the earthed exposed conductive involves:separation by insulating materialsseparation by linear clearances in gases ( in air) or by creepage distances along insulators ( to prevent flashover on electrical switchgear).Insulation is characterised by specific voltages which, in accordance with standards, apply to new products and equipment:insulation voltage (highest voltage on system )lightning impulse withstand voltage (1. /50 s impulse wave)power frequency withstand voltage ( U + 1000 V/1 min).Example for an LV switchboard of the Prisma type:insulation voltage: 1000 Vimpulse voltage: 1 commissioning a new installation, produced in accordance with standard working practices with products manufactured as per standards, the risk of an insulation fault is extremely low.
