10 Units -  Transformer Rectifiers 

• (7) Units are fed at 10 kV
• (3) Units are fed at 132 kV
• Rated DC Current of Rectifier Group 1: 26 kA
• Rated DC Current Per Rectifier Unit: 26 kA
• Rated DC Voltage: 710V
• Control Range by Means of OLTC and Transducer 710-300V
• Circuit Arrangement: 1 x 3 ph Bridge
• Phase Effect Per Rectifier Unit: 6-Pulse
• Phase Effect of Rectifier Group 1: 6-Pulse
• The three phase oil filled rectifier transformer arrangement is designed for outdoor installation and consists of one step-down transformer and one rectifier transformer in back to back design as well as the OFWF cooling equipment, protection and monitoring auxiliaries.
• The transformer is equipped with an on-load tap changer in order to optimize the power factor of the system and to minimize the distortions to the feeding power network.
• The mechanical arrangement of the low voltage bushings will be identical to the transformers supplied by Siemens for Rectifier groups AC and EG. This way the new transformers are interchangeable with the transformers installed in group AC and EG.
