    6.6kV - 1250kVA Dry Type Transformer Explosion Proof Two Winding Transformer


    6.6 kV - 1250kVA Cast Resin Dry Type Transformer, Three Phases, Two Winding, Power Distribution

    Introduction

    As per IEC60076 standard required, cast resin dry type transformer designed and manufactured by Pearl Electric is welcomed in home and abroad with features of low loss, artistic apearnce and compact size.
    Scientific computing tools:

    We use advanced electric, magnetic, thermal and mechanical computing software to calculate electro-magnetic field and magnetic flux leakage distributions, to analyzewave processes, and to select reliable insulation margin, thus to guarantee product reliability, enable low noise level,clamp-proof,anti-fouling,high mechanical strength, flame resisting, strong overload ability and low partial discharge quality.

    Short Duration AC Test


    The test shall be carried out according to Clause 12.2 of IEC 60076-3 for transformers with
    uniformly insulated high voltage windings and paragraph 12.3 for transformers with nonuniformly
    insulated high voltage windings.


    Partial Discharge Measurement


    Partial discharge measurements shall be performed on all dry-type transformers. Measurement
    shall be made in accordance with IEC 60076-11, IEC 60270 and with Annex A of
    IEC 60076-3. The partial discharge measurement shall be carried out after all dielectric tests are
    completed. The maximum allowable level of partial discharges shall be 10pC.


    QUALITY ASSURANCE


    The manufacturer shall comply with all policies and procedures set forth in China State Grid Quality Assurance and Procedures handbook for the whole duration of the contract.
