Instrument Earth (IE) An earth reference that is normally used to reference measurements ofelectrical signals.Protective Earth (PE) An earth reference that is normally used as a coupling path forunwanted electrical signals, like transients and over-voltage. The chassis or framework of the installation is normally considered to be the local Protective Earth. As the name implies, it is intended to provide a safe electrical potential for human safety.GroundSynonym for Earth.PowerLoop Cabling - Guidance TableType of shield (Dual) Foil + braidFoil + foilBraid+braidFoil/braid +braid or Foil/braid + foil/braidCharacteristics Tradeoff to make good attenuation at both high and low frequencies.Optimised for high frequency.Improved attenuation in low/mid frequency range (compared to single braid shield). The extra foil in one (or both) of the shield layers improves attenuation both at high and low frequencies.
