The invention relates to a high altitude area 750 kV shunt reactor local discharge test device, which comprises a variable frequency power supply, an isolation transformer T, a series resonant capacitor C0, parallel compensation capacitors C1 and C2, a tested reactor L0, a wave resistance reactor LP and a local discharge measurement loop PD. Through the device, a local discharge experiment can be done on the 750 kV shunt reactor in the high altitude area of Qinghai to test the insulation performance, and the shunt reactor can be ensured to operate normally and safely.
