General

This
outdoor epoxy resin type combined current transformer/voltage
transformer metering instrument transformer (metering units, MOF), used
in  current transformer used in 3.3kV, 6kV, 10kV, 11kV, 12.5kV and 13.8kV power system, for measuring energy, power line protection, and control. to be MV prepaid metering system.


It have been used in outdoor pole mounted and transmission line.
The
voltage transformer made from outdoor high quality ultraviolet-proof
epoxy resin, high quality CRGO core for metering, primary and secondary
use pure electrolytic copper, both winding and core have shielding
processing.

This
combined instrument transformer, can combined from 2 Current
transformer and 2 voltage transformer to be 3 phase 3 wire, also can
combined from 3 current transformer and 3 voltage transformer to be 3
phase 4 wire.

2 voltage transformer structure use V/V connection, 3 voltage transformer structure use Y/Y connection.


Outdoor
vacuum circuit breaker can work as recloser, automatic protection,
metering with smart prepaid meter, if no money one prepaid meter, MV
power line automatic cut down, if charge money on prepaid meter, power
automatic power recovery.

It has default phase protection, overcurrent protection, overvoltage protection, and other relay protection functions.


11kV medium voltage prepaid metering transformer.
Current transformer + voltage transformer + Vacuum circuit breaker(recloser) = MV prepaid metering system.


Standards
All
UNISUN Electric instrument transformers are in conformity with IEC
standards, and recommendations IEC 61869. Transformers in conformity
with specific country standards can also be supplied. (IEEE C57.13,
NBR6855).

All
vacuun circuit breakers conform to the IEC 62271-100, CEI – VDE – BS
Standards are equivalent to IECStandards due to harmonization with IEC
