Any change in relay primary site will never affect on tripping but in case we change ct secondary ratio then it may be send a tripping cammand to cb according to relay setting.
Tripping pe koi farq nahi padega... Because relay, normal current ko wrong setting ke according pad rahi hai... To abnormal current bhi usi ke according padegi
