Abstract: Metalized films are important winding material for film capacitors, and investigating the space charge effect is critical for improving the insulation performance. In this work, a picosecond pulsed laser induced pressure pulse (LIPP) system for space charge measurement is built up. The space charge distribution in metalized biaxially oriented polypropylene (BOPP) films with a thickness of 12μm and 6μm is obtained as an example. It is verified that the amount of homopolar charges increases with the applied electric field, and when the applied electric field is strong, a non-linear effect appears, which is more pronounced for the metalized side with negative polarity. The even more significant non-linear effect and charge injection for the physical contacting (non-metalized) side indicate that the metallization can weaken the interface space charge effect. With the decrease of film thickness, the peak width of space charge decreases, while the front of the peak increases. The results in this work verify the feasibility of the picosecond pulsed LIPP method to measure the space charge distribution in metalized films with a thickness on the order of 10μm or thinner, and provide a reference for investigating the space charge effect and improving the insulation performance.
