Areva, Electronic Edition, 2004. — 18 pages.The MiCOM P140 is a numerical 3-phase overcurrent, earth fault and sensitive earth fault relay, with 4 protection stages each. These elements can be used for 3 phase differential protection or restricted earth fault (REF) protection. It is recommended that the I>1 is used as the main protection element for 3 phase differential protection and the I REF >I S for the REF applications. The I REF >I S enabled by selecting "Hi 2 REF" (SEF/REF PROT’N/SEF/REF options). The time delay characteristic should be selected to be definite time and with a setting of zero seconds.Table of Contents:Comms Options MiCOM Px40 Platform.
