O conjunto de aterramento
temporário é um dispositivo utilizado para proteção dos eletricistas durante os
trabalhos em redes desenergizadas, cuja finalidade é curto-circuitar e aterrar
a rede de distribuição de energia elétrica, contra uma eventual energização
acidental.



O sistema de aterramento é formado por um conjunto de “garras” metálicas
ligadas a uma haste de cobre, através de condutores.



&nbsp;A instalação do conjunto de
aterramento deve obedecer aos procedimentos abaixo: 



1.&nbsp;&nbsp;&nbsp;&nbsp; A haste de cobre deve ser ligada firmemente à terra
(aterrada). Em seguida, as garras metálicas devem ser conectadas,
separadamente, a cada um dos condutores do circuito em que se vai trabalhar;



2.&nbsp;&nbsp;&nbsp;&nbsp; Na retirada, após a conclusão dos trabalhos, deve
se desligar em primeiro lugar as “garras” presas em cada condutor do circuito
e, em seguida, a extremidade ligada a terra;



3.&nbsp;&nbsp;&nbsp;&nbsp; A quantidade de conjuntos de aterramento temporário
a serem instalados dependerá da configuração da rede, ou seja, garantir o
aterramento a montante (antes) e a jusante (após) do local que o eletricista
deve trabalhar.



Aterrar as instalações elétricas, durante as manutenções, é um
procedimento de segurança obrigatório que visa proteger o trabalhador contra
energização acidental. 



Portanto, é de suma importância a realização dos procedimentos, acima,
de instalação e retirada do equipamento, que conjuntamente com o aterramento
das redes, são indispensáveis para segurança dos eletricistas que atuam no
sistema de distribuição.
