Restricted Earth Fault Relay Connection Diagram 13+ Pages Explanation in Google Sheet [2.6mb] - Updated 2021
Open 31+ pages restricted earth fault relay connection diagram solution in Doc format. 31Restricted Earth Fault REF means an earth fault from a restrictedlocalized zone of a circuit. Ideally in healthy condition residual current should be zero to relay coil however current transformer measurement errors this current is not necessarily zero. The main earth-fault protection is provided by the restricted earth-fault current stage I0 which operates instantaneously when the dif-ferential current exceeds the set start value of the restricted earth-fault stage. Read also fault and restricted earth fault relay connection diagram The knee voltage U Kn is an important characteristic of the transformer.
Relay Menu Database. Earth leakage relay ELR and core balance current transformer CBCT ZCT have been widely used and accepted because these have field adaptability and are economic.

The term REF protection method means not to sense any earth faults outside this restricted. When used as zero-current differential protection restricted earth fault the re-lay IRI1-ER is to be connected acc. The transformer does not work linearly anymore above this voltage. 19protection restricted earth fault the relay IRI1-ER isIRI1-ER to be connected acc. 23As shown in figure above there are a total of four Current Transformers CTs three CTs connected in each phase ie. Typical transformer restricted earth fault protection arrangements are shown in section 21.
