Abstract

As modalidades apresentadas aqui referem-se a um pára-raios com espaçamento externo, EGLA, para linhas de transmissão. O EGLA compreendendo uma unidade de varistor em série SVU (l) que tem uma primeira extremidade e uma segunda extremidade, a SVU configurada para ser conectada entre uma linha de transmissão e o solo, uma unidade de espaço primário de faiscação (8) conectada em serie à primeira extremidade da SVU, um espaço secundário disposto entre a segunda extremidade da SVU e o solo, e o espaço secundário conectado em serie à segunda extremidade da SVU, um dispositivo de ligação em curto (3) conectado em paralelo com o espaço secundário, e um dispositivo de desconexão (4) disposto no dispositivo de ligação em curto, o dispositivo de desconexão configurado para abrir o dispositivo de ligação em curto (3) quando a SVU é sobrecarregada. Um método para proteção de impulsos executado por um EGLA também é apresentado.
