Claim:
1. A system for measuring a loss in power between a power transmission side and a power reception side in a high voltage direct current (HVDC) system, the system comprising: a first loss measurement unit installed at the power transmission side, a second loss measurement unit installed at the power reception side, and a main control unit storing identification information on each of the first and second loss measurement units, wherein each of the first and second loss measurement units is installed at a respective location at which a current or voltage is measured, and comprises: a respective voltage sensor for measuring a voltage, a respective current sensor for measuring a current, a respective GPS module for providing time information on when measurement is performed by the voltage sensor and the current sensor, and a respective storage unit storing the time information along with a voltage value and a current value measured by the voltage sensor and the current sensor, wherein the main control unit is configured to; receive the respective voltage and current values measured by each of the first and second measurement units, and calculate a loss in power between the first and second loss measurement units according to the received voltage and current values.
