We investigated both maximum pressure and pressure distribution by strikes of lightning impulse discharge using pressure measurement film attached to ground electrode. As a result, we found that pressure distribution due to discharge was almost circular with locally distributed high pressure points. Maximum pressure due to discharge was 5.9 MPa, 9.2 MPa and 8.5 MPa at applied voltages of -600 kV, -700 kV and -800 kV, respectively.
