CT VT Combined 11kV 23kV to 220V Silica Gel Insulation 12V AC Transformer

CT VT Combined 11kV 23kV to 220V Silica Gel Insulation 12V AC Transformer 

Transformer Silica Gel Insulation 

This combined instrument transformer is for use with electrical measuring instruments and electrical protective devices. It consists of a current transformer and a voltage transformer in the same case.

Our combined instrument transformer is especially suitable for HV metering, to do so, two voltage transformers shall be connected in V type, while two current transformers connect serially to phase A and C. The instrument transformer can be fixed on the post of transmitting line. The secondary output connects directly to an independent HV metering box. Users can choose certain connection in accordance with different conditions.

1).Rated Voltage (kV): up to 35kV

2).Rated Primary Current: up to 1000A or custom specified

3).Rated Secondary Current: 5A

4).Accuracy Class: up to 0.2s for metering; up to 0.2, 0.5 for protection

5).Rated Frequency: 50Hz (60Hz on request)

6).Installation: outdoor

7).Insulation Material: epoxy resin and silicon jel

8).Winding: high quality enameled copper wire

* Except for the technical parameters list above, we can design as per clients’ requirements.

1).A metering unit consisting of one CT and one VT

2).With small volume and good performance

3).Multi-taps at the secondary windings, which makes different current transformation ratio for the current exchange of customers while power consumption increasing

Notes: Detailed technical data and outline drawing shall be provided under request.

1.The instrument transformers are packing with wooden packages, and must always stand up according to the direction mark of the packages (except for the 220kV current transformers, they are always packing and transport by lying down).

2 You must remove the wood plates of the top and obverse when you open the package, and then dismantle the 4 pcs M16 bolts which fix in the frame of the package, lift up the voltage transformer vertically and slowly from the package.

3 The clients must check the packages when they receive the voltage transformers, if a package has been broken, they must open the package to check the product together with the forwarder, note down the process and send to the manufacturer.
