    technical specification

    1.  Ambient temperature:-25℃~40℃;

    Note: By customize manufacture,the ambient temperature can be as low as-40℃.

    2.Altitude:≤1000m;

    3. Pollution class:IV;



    ● Rated insulation level: 12/42/75kV.

    Rated secondary winding current:5A/1A.

    The rated current and accuracy class are displayed in the table below.

    Partial discharge (PD) level meets standard IEC60044-1.

    When transformer is working with computer, the lower limit of secondary load can be as low as 1VA for accuracy class 0.2 and0.5.

    Structure feature

    1. Cores and windings are cast together in epoxy resin.

    2. The transformer cores are manufactured of high-grade magnetic material.

    3. The transformer is fixed to the base plate by four screws.

    4. The bolted earthed clamp is located on the transformer base plate.

    5. The secondary terminals are covered with a protective cover.

    6. As the high level of insulation,it can work normally in damp and Pollution II condition.

    7. The cores and windings are cast together.

    8. Three optional ways of installation,correspondent to product version of A/B/C.

    9. The outlet terminals of theprimary winding and secondary winding, are respectively marked as P1,P2 and S1,S2.

    10. The case that, primary current runs from P1 to P2 and secondary current flows from S1 to S2 through external circuit, is called subtractive polarity. The secondary circuit should not be open, when primary current is flowing. Otherwise,a high voltage will be generated.

    11. The transformers are equipped with primary winding and secondary windings.The windings are fixed to the iron core bar by casting,

    12. For the two secondary windings,the first one is for either measuring or protecion purposes; the other is for being connected into an open-delta connection in a three-phase system.

    13. The outlet of the primary winding is insulated from the earth to a correspondent level.

    14. The secondary terminal board is covered with a transparent cover made of plastic.
