Disclosed is a switchboard for measuring a current and a voltage. The switchboard for measuring a current and a voltage includes a housing which connects a power supply device to an input terminal and connects a plurality of loads to a plurality of output terminals, a plurality of coils which are formed in the housing and are serially connected between the input terminal and the output terminal, a magnetic sensor which is formed in the coil and senses the change of the magnetic field in the coil, a temperature sensor which is formed in the coil and senses the temperature change of the coil, a fixed resistor which is connected to both ends of the coil in parallel for measuring the voltage, a magnetic field shielding box which shields an external magnetic field by surrounding the coil, the magnetic sensor, the temperature sensor, and the fixed resistor with an electromagnetic wave shielding material, and a shielding wall which is formed between the magnetic field shielding boxes and excludes mutual interference of the magnetic field shielding box. |
