NGRGENERATOR MIDDLE POINT RESISTOR PANEL
1.TECHABICAL DATA
WHEN THE GENERATORS LOOP HAPPEN THE SINGLE EARTHING,THE CURRENT WILL BE BIGGER THAN THE RATED CURRENT ,IT WILL MAKE THE EARTHING OVER VOLTAGE IN ARC LIGHITNG,FOR THE IT IS LOWER LEVEL OF GENERATOR 'S WITHSTAND VOLTAGE,INSULATION WILL TO BE EASY TO BE SHATTERED.IF IT MAKE OVER CURRENT OF EARTHING,THE GENERATOR 'S CORE WILL BE BURNED AND SINTERED. IT IS USUALLY TO SET THE MIDDLE POINT TO EARTH BY HIGH VOLTAGE RESISTOR TO LIMITE THE ARC LIGHT OVER VOLTAGE,AND TO LOMITED THE CORE OF THE GENERATOR TO BE BURNED AND SINTERED,IN THE SAME TIME,IT WILL IMPORVE THE DELICACY DEGREE OF THE RELAY PROTECTION,EFFECTIVE TO THE TRIP TO MAKE THE LIMITED OF 2.6TIMES OF THE VOLTAGE BETWEEN PHASESES FOR THE OVER VOLTAGE TO LIMIT THE ARC TO BE REBURNED
,AND TO PROTECT THE MAIN INSTRUMENTS AND LIMITE THE CORE MAGNETISM SYNTONY OVER VOLTAGE,FOR SAFETY RUNING OPF THE GENETATOR.
