[/ˈvoʊltɪdʒ raɪz/]
nounpl: voltage rises
elevação de tensão
1. An increase in electrical potential or voltage in a circuit or power system, often caused by sudden load changes, switching operations, or lightning strikes
The voltage rise in the transformer caused the protection relays to activate.
A elevação de tensão no transformador causou a ativação dos relés de proteção.
2. The voltage increase across an electrical component or conductor due to current flow and resistance
Engineers calculated the voltage rise across the transmission line during peak load conditions.
Os engenheiros calcularam a elevação de tensão na linha de transmissão durante condições de pico de carga.
3. In power quality terms, a temporary or transient overvoltage condition in an electrical system
The voltage rise was detected by the power monitoring equipment and recorded in the system log.
A elevação de tensão foi detectada pelo equipamento de monitoramento de energia e registrada no log do sistema.
This is a specialized technical term used primarily in electrical engineering, power systems, and utility industries in both Brazil and the United States. In Brazil, 'elevação de tensão' is the standard terminology used in ABNT (Associação Brasileira de Normas Técnicas) standards and by utility companies like Eletrobras. The concept is critical for electrical safety and equipment protection in both countries.
