description The invention relates to a power output ground insulation impedance circuit and a calculation method thereof, and the circuit comprises a to-be-measured point A. The to-be-measured point A is connected with one end of a resistor R2 and one end of a resistor R3, the other end of the resistor R2 is connected with one end of a resistor R1, one end of a first switch and one end of a second switch, and the other end of R1 is connected with a voltage positive electrode and one end of a resistor RX. The other end of the resistor RX is respectively connected with one end of a resistor Ry and the other end of the second switch and then is grounded PG, the other end of the resistor Ry is respectively connected with a voltage negative electrode, one end of a resistor R4 and the other end of the resistor R3, and the other end of the resistor R4 is connected with the other end of the first switch. According to the invention, the insulation resistance value can be tested at regular time without human intervention, and a fa
