EARTH RESISTANCE VALUE CALCULATION SYSTEM OF NEUTRAL POINT RESISTANCE GROUNDED METHOD

摘要

PROBLEM TO BE SOLVED: To provide a system for calculating an earth resistance value of a neutral point resistance grounded method for suppressing waste of wasteful power by securing safety of persons and facilities.;SOLUTION: The system is designed by using the calculation system for automatically calculating the optimum earth resistance value by inputting a power supply system specification and allowable body current. System protection during a short circuit accident, electric shock prevention to men and beasts and suppression of power loss are enabled, effect for efficiency improvement of the system design exists.;COPYRIGHT: (C)2007,JPO&INPIT
