Transformer non-electric quantity protection test system and method

The invention discloses a transformer non-electric quantity protection test system and method. The system comprises an interlayer energy supply transformer protection unit, a main energy supply transformer protection unit, a communication switching device, a first communication unit, an exhaust control unit, a first logic processing unit, a monitoring system and a test control host. The exhaust control unit is used for controlling the main energy supply transformer to execute exhaust operation, so that the non-electric quantity detection value of the main energy supply transformer is reduced; the communication switching equipment is used for responding to an interlayer energy supply transformer protection test signal, and enabling the interlayer energy supply transformer protection unit to be in communication connection with the main energy supply transformer through the first communication unit; the interlayer energy supply transformer protection unit generates a first protection signal of a corresponding le
