Product Description

 

Product Introduction

Combination Instrument Transformer

   

The 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 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.

 

 

 

Product Advantage

1.Reliable Structure

   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.
