Combination Instrument Transformer The combined instrument
transformer have 5 version with different voltage 3/6/12/36KV.The
transformer are designed for 3 phase electric systems of rated
frequency of 50/60Hz.The products are used in metering electric
energy, voltage controlling and relay protection
applications.Technical specification:1 - Rated
voltage:6KV/12KV/36KV.2 - Accuracy class:0.5/0.2 and
0.5s/0.2s.3 - Rated voltage ratio:6kv/100; 1k/100; 3300/1004
- Rated current ratio: 5-300/55 - Note: The products may be
custom manufactured to a higher ratio.Structure featureThe product
mainly consists of combined instrument transformer and watt-hour
meter. The combined transformer is equipped with 2 or 3 single
phase VT and CT units.The transformer is insulated in 25#
transformer oil. The outlet terminals of primary and secondary
windings are encapsulated in porcelain bushing and fixed on the
panel.Watt-hour meter tank is fixed on the flank of combined
instrument transformer and comprises one active watt-hour meter and
reactive watt-hour meter. The products are reliable, accurate,
light and convenient in installation. They are also designed
against stealing electricity.1 - The transformer equipped
with primary and secondary winding. The windings are fixed to the
iron core bar by casting.2 - For the two secondary windings,
the first one is for either measuring or protection purpose; the
other is for being connected into an open-delta connection in a 3
phase system. 3 - The outlet of the primary winding is
insulated from the earth to a correspondent level.4 - The
secondary terminal board is covered with a transparent cover made
of plastic.5 - The bolted earthed clamp is located on the
transformer base plate.6 - The transformer is fixed onto the
base plate by four screws. Founded in
