Device for providing support for resetting intelligent instrument

There is provided an apparatus for providing support for resetting a smart meter, configured to be connected between the smart meter and a consumer facility, and comprising: an inductor for connecting to a separate tap between the smart meter and the consumer facility; a capacitor electrically connected to an outlet terminal of the inductor and electrically connected to a neutral line; a relay; and a control circuit of the relay, wherein an electrical contact of the relay is sandwiched between the capacitor and the neutral line. When the intelligent instrument detects that the electric power consumption is lower than or equal to the contract electric power, the relay is configured to be in an active mode and is connected with the capacitor; when the smart meter detects that the electrical power consumption is higher than the contract electrical power, the relay is configured to a standby mode, disconnecting the capacitor and thus modifying the impedance of the device. 提供了一种为重置智能仪表提供支持的装置，被配置为连接在智能仪表和消费者设施之间，并
