Monopolar current and voltage sensors integrated

The invention discloses a unipolar current-voltage integration sensor, relating to an electronic sensor in the field of intelligent power grids. The sensor comprises a current sensor, a voltage measurement sensor, a voltage correction sensor, a signal modulation circuit, an A/D (Analog to Digital) conversion circuit, an FPGA (Field Programmable Gate Array) unit, a wireless transmission extension unit and a high-voltage electricity getting device. A current signal of a power transmission line is collected by the three sensors and the signal is processed. After a voltage value of tested current is calculated, detection information is transmitted through a wireless communication network. The high-voltage electricity getting device can be used for supplying electric energy to online monitoring equipment for a long time by getting energy through a current transformer and cooperatively supplying power with a lithium cell. According to the unipolar current-voltage integration sensor disclosed by the invention, current and voltage information can be transmitted to the computer to be subjected to data processing rapidly, integrally and accurately; high voltage, large current and ferromagnetic resonance cannot be generated; the sensor can be conveniently connected with an electronic instrument and micro-computer measurement and control protection equipment; the system structure is simplified; the space is saved; the energy consumption is very low; and the stability and the accuracy of the whole system are improved.
