FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering, as well as fire safety and can be used to test protection devices against parallel arcing and spark gaps, installed in electrical networks or electrical installations. The method for checking protection devices against parallel arcing and spark gaps is characterized by the use of a cable sample with parallel conductors to carry out a checkup in parallel arc breakdown mode, thereby ensuring the reliability and fire safety of electrical networks and electrical installations.
EFFECT: ensuring the verification of the characteristics of protection devices against parallel arcing and spark gaps.
