When lightning occurs and generates the overvoltage, the over-voltage current can pass transient voltage between lines and ground to suppress diodes VD2, VD3 from connecting to the earth, and their ground voltage difference is further inhibited by the bipolar transient voltage suppression diode VD1 between two lines, so that the equipment is protected.
