Abstract: The test procedure for high-voltage oil fi lled electrical equipment (VMEO) for explosion safety is considered. An arc-less source of impulse pressure is described, which is designed to simulate the effect on the VMEO of an arc discharge due to an internal short circuit. A technique for applying this source has been developed. On the example of testing current and voltage measuring transformers, the experience of using BIID is generalized. The tests of the damper system of protection of the VMEO from the explosion were carried out.
