(46) 

Current unbalance function (CUB) is used for instant- and time delayed unbalanced network 
protection and detection of broken conductor for various applications including feeder, filter 
and machine applications of utilities and industry. The number of available instances of the 
function depends of the IED model. Function measures constantly negative- and positive 
sequence  current  magnitudes  which  on  the  operating  decisions  are  based.  In  broken
