IMPROVING THE RELIABILITY OF CRITICAL ELECTRICAL POWER ASSETS
Porque monitorar online instalações elétricas?
Evitar ou reduzir riscos de acidentes e consequentemente: Evitar paradas de produção não programadas Evitar danos em equipamentos e pessoal Aumentar a segurança Aumentar a confiabilidade
DESAFIOS EM INSTALAÇÕES ELÉTRICAS
82%De falhas elétricas
são aleatórias
25 anos+Instalações antigas
50%Custo adicional
Para reparar painieis após acidente ao invés de monitorar antes da falha
$15M+Media de custo de
acidente
20%Das paradas
industriais são decorrentes de falhas elétricas
31%Empregados possuem pouca bagagem de conhecimento
Devido ao pouco tempo de experiência
O que deve ser monitorado para reduzir riscos de falhas ou acidentes?

DIFERENÇAS INSPEÇÕES MANUAIS VS. DADOS ONLINE
• INSPEÇÕES MANUAIS
• MONITORAMENTO ONLINE IntelliSAW
• MAIS SEGURANÇA• MENOS ACIDENTES• MAIS PONTOS MONITORADOS• DADOS CONTINUOS• AUMENTA A CONFIABILIDADE• AUMENTA A DISPONIBILIDADE
• NÃO ACESSA TODAS AS FALHAS
• EXPOSIÇÃO DE PESSOAS• AINDA ASSIM OCORREM

South East Generation Plant - GCB Maintenance
CHALLENGE RESULTS
The IntelliSAW CAM platform triggered alarms, bringing attention to the thermal rise on a GCB contactors.
Confirmed deterioration of 4 of the 6 GCB connections. Saved $350k+ for new asset.

Peak power plants require several cold-starts to meet demand, and in high humidity environments, this operation causes significant corrosion.
Frequent manual inspection and forced downtime is required to prevent system failures.
BASF – Outdoor Transformer Preventive Maintenance
Secondary side bus duct had a gasket failure where moisture was getting in. You could say the system just paid for itself.
