| description | The utility model relates to a standard resistance system for calibrating an insulation resistance meter. The circuit comprises a plurality of standard resistors connected in series. The plurality ofstandard resistors are connected in series; the resistors are sequentially connected in series from small to large according to the resistance values of the standard resistors; the plurality of standard resistors which are connected in series are averagely divided into n resistor units. The resistance values of the standard resistors of the resistor units are the same; a first standard resistor inthe plurality of standard resistors connected in series is connected with a relay in series and then is connected to a wiring end A; the last standard resistor in the plurality of standard resistorsconnected in series is connected with a relay in series and then is connected with a bus; two adjacent standard resistors in the plurality of standard resistors connected in series are connected witha bus through leading-out wi |
