2. Assignment:
Three-phase voltage transformers oil NAMI type with additional windings for insulation control, designed for large-scale conversion of the electrical AC voltage to further measure and feed devices for protection and alarm circuits automation with isolated neutral. Used for lowering high voltage of 6 or 10 kV to 100, and records, including commercial and protective devices in electric power in the electrical AC. The transformer complies with the requirements of Technical condition 659 RK 0001 0033-22 and GOST 1983-2001.
Transformers are not designed to operate under conditions of shock, vibration, explosive, and reactive environment.
