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.

MAX TEMP

Rate of Change

Differential

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.
