Cast resin step-up transformers

DESCRIPTION
This type of transformer is realized with cast resin HV winding and with impregnated low voltage winding. The HV output is located in the upper front side of the cast resin winding.
This type of transformer is only for indoor.
The cast resin transformers are designed for not-continuous operation (normally 5 'ON - 20' OFF), but it is possible to design to continuous operation
Between the low voltage and the high voltage windings is present an electrostatic screen which ensures a perfect electrical insulation in the event of failure of the object under test.
All cast resin transformers are Corona free and so recommended for PD test. The main benefits of these transformers are the following:

  • very low work Induction to ensure a perfect sine waveform, with low harmonic distortion on the test circuit
  • Different cooling possibilities of:
    o AN
    o AF
  • Possibility to include a electrical or pneumatic earthing system of HV pole.
  • Possibility to modify the transformer design to decrease or increase the impedance voltage (if possible), according to customer request.
  • Possibility to realize a test portable solution including control desk and voltage regulator (AMETest COMPACT system)

 

OPERATING CONDITIONS:

09tab01

1) Without condensation
2) For different sea level heights installation is necessary to reduce accordingly the max working voltage
