ATACAMA PV PROJECT 170MW IN CHILE-METKA EGN

On a strip of land on the Pacific coast, west of the Andes Mountains, lies the Atacama Desert, the driest nonpolar desert in the world. SENEKIS LTD has been developing one of our most ambitious and challenging projects yet, supplying for this huge PV plant 170MW state of the Art MV Switchgear, Transformers, LV Switchboards.

 We can finally share with you the stages of its development. We are more than proud of our staff, our partners and our collaborators for making this project a reality.

  After rigorous development, we finally began preparations & testings before moving our products for transportation.

 For this particular project called ‘Atacama’ in Chile, we supplied among others:

 -  The provided switchgear 8DA10 is an SF6-insulated, type-tested, single-phase metal-enclosed medium voltage vacuum interrupter switchgear designed as single-busbar switchgear for indoor installation.

 -  The SF6-gas is only used as insulating, but not as quenching medium. The insulation level required is maintained inside the gas compartments without additional insulation material. Enclosures have degree of protection IP65.

 -  The single pole encapsulation with modular housings consists of corrosion-resistant aluminium housings. The modular design allows the replacement of the panel connection housing or the circuit breaker without interrupting the main horizontal busbar operation. Each closed gas compartment has its own pressure relief which prevents rupture of the housing in case

of an arc fault. The monitoring of the gas compartment is carried out with alarm contact manometers.

 - Design:

* 16 panels (2 Incomers 2000A+1 Bus coupler 2000A+13 feeders  1250A) 8DA10 38 (33kV) – 31.5kA*3s – IAC A FL Total width 9904 mm

 * Protection Relays SIPROTEC 7SJ82 incomers + 7SJ8041 Coupler + 7SJ8011  13 pcs

 * Metering devices Janitsa UMG-604E 4pcs+ Pm180 SATEC 2pcs

One of the most crucial components of the ‘Atacama’ Project in Chile is our very own Aux General Low Voltage Panel.

 The purpose of the GLVP is to meet the electrical consumption needs of the project

 - Characteristics of the GLVP:

* Type SIEMENS SIVACON S4, IP41, 400A, 10kA, Automatic Source change over with SENTRON 3KC ATC6300 transfer control device.
