Construction of the Mornaguia Power Plant

Construction of the Mornaguia Power Plant 640MW :

• 2 × Ansaldo Energia Gas Turbines × 320 MW.
• BEST Electrical Transformers 420+220 MVA 225/15 kV.
• Commissioning of the 6.6 kV MV Electrical Substation.
• Telephone and Intercom System.

Commissioning of the 6.6 kV MV Substation:

• Testing and commissioning of the substation.
• Control, command, and protection testing.
• Dielectric test of the busbar compartment with “Generator Circuit Breaker”.

Complete Commissioning of the Transformer:

• Installation and connection of the transformer.
• Analysis, filling, and treatment of transformer oil.

Execution of Electrical Tests on the Transformer:

• Measurement of the transformation ratio (Ratio Test).
• Measurement of winding resistance.
• Measurement of insulation resistance and polarization index.
• Dielectric tests and power factor measurement (Tan Delta).
• Short-circuit impedance measurement.
• Measurement of no-load and load magnetizing current.
