The invention relates to an anti-power-theft high-voltage user load intelligent measurement analyzer which comprises a current transformer, an analog-to-digital conversion part and a data calculation part. The current transformer comprises a left half magnetic core and a right half magnetic core. The left half magnetic core and the right half magnetic core can form a closed annular magnetic core through driving of a closed loop mechanism. A secondary side winding winds the annular magnetic core. The current transformer transmits measured data to the data calculation part in a wireless transmission manner. After the CPU of the data calculation part performs calculation, a calculation result is displayed through a display device. Wireless receiving and liquid crystal display are utilized in the anti-power-theft high-voltage user load intelligent measurement analyzer. An operator only requires inputting of related parameters such as measured voltage grade and comprehensive ratio and waiting for several seconds, the anti-power-theft high-voltage user load intelligent measurement analyzer can accurately determine whether power theft exists, thereby displaying real load condition of a user and predicting mis-wiring.
