WebbDistance protection is a mature protection mainly used in transmission systems . It is based on the observation that the protected line impedance is proportional to its length: monitoring changes in the impedance (e.g. by measuring locally voltage and current) thus enables the identification of a fault without any communication device. WebbRelion® Line Differential Protection Line Differential Protection An alternative principle for line protection that is quickly becoming the norm is differential protection. Differential protection is based on Kirchhoff’s laws, stating that all current into a network node shall add up to 0 in an ideal system.
