Bus current transformers ASTER TT-V series, etc.

Measuring current transformers are designed to transmit a signal of measuring information to measuring, protection, automation, alarm and control devices in AC electrical circuits with a frequency of 50 Hz and a voltage of 0.66 kV.

• Bus transformers - a bus or cable installed in the window of the transformer magnetic circuit is used as the primary winding.
• The design of current transformers is an annular magnetic circuit with a secondary winding.
• They are installed in complete switchgears of the internal installation of electrical substations and are components.
• A large selection of housing sizes with nominal primary currents – from 100 to 5000 A, with a nominal secondary operating current - 5 A.
• Accuracy classes are 0.5 and 0.5S.
• The housing is made of a material that does not support gorenje.
• Installation both on the mounting plate with screws, and directly on the conductive busbar with special clamps.
• Universal mounting on the bus using 4 guides on the transformer housing and a universal sleeve with a self-tapping screw and an insulating spacer that can be installed in any of the guides.
• Convenience of color marking of phases: in the package of group packaging (3 pcs) there are 3 color panels installed under the transparent cover of the terminals: yellow, green, red.
• They are included in the State Register of Measuring Instruments, have a type approval certificate issued by the Federal Agency for Technical Regulation and Metrology.
• The verification interval is 12 years.
• Comply with GOST 7746, GOST 8.217-2003.
