Australian company Noja Power has provided technology at many of the venues currently in use for the FIFA World Cup in Brazil.

The electrical switchgear firm has supplied its OSM series automatic circuit reclosers (ACR) at several stadiums.

The OSM15 ACRs were installed in Castelão Stadium (pictured) which will host six of the tournament’s games, including last night’s clash between Brazil and Mexico.Castelão Stadium

The ACRs, which have a maximum rated voltage of 15.5kV and a rated continuous current of 800A, are used in an auto change over (ACO) configuration to ensure continuity of electricity supply.

One ACR is fitted to the stadium’s primary feeder with an additional unit on a secondary feeder. In the event of a problem with the primary feeder, the ACR opens to isolate the line, while the second unit automatically closes to activate the secondary feeder to supply stadium power while the primary line is repaired.

OSM15 ACR’s were also installed this year to provide overcurrent protection for the training centre of the Italian team in Mangaratiba, near Rio de Janeiro, while OSM27 ACRs are providing overcurrent protection for feeders of several stadiums in Belo Horizonte which are being used as training camps for the teams from Argentina, Uruguay and Chile.

Bruno Kimura, managing director of Noja Power Brazil, said: “The 2014 FIFA World Cup and the 2016 Olympic Games in Rio de Janeiro will focus the eyes of the globe on our country. It is therefore very important that the facilities for these events are seen to be world-class. I’m pleased that Noja Power Brazil is performing an important part in this respect by providing the equipment that will help ensure reliable electricity supplies so that players and fans can enjoy the spectacle without interruption.”
