Electrical Field Service
Electrical Field Service Condition Monitoring
is a process that uses a variety of technologies to monitor the condition of electrical equipment. This information can be used to identify potential problems before they cause a failure, which can save time and money.
Afriphase Electrical has a team of experienced engineers and technicians who are experts in EFSM. We can help you to identify potential problems with your electrical equipment before they cause a failure. This can save you time and money, and it can help to improve the reliability of your equipment.
Risk levels are aligned to international standards and displayed on an interactive Asset Health Portal where the levels can be trended from assessment to assessment.
Interpretation of Condition (risk) levels
| Levels | Description |
|---|---|
| Level 0 | Asset Not assessed |
| Level 1 | No discharges (PD) were detected |
| Level 2 | Low discharges (PD) were detected |
| Level 3 | Moderate discharges (PD) detected, follow up assessment required |
| Level 4 | High discharges (PD) were detected, advanced diagnostics required |
| Level 5 | Highest probability of imminent failure, isolate and shut down if possible |

Here are some of the benefits of EFSM:
Increased reliability
By identifying and fixing problems before they cause a failure, EFSM can help to improve the reliability of your equipment.
Increased compliance:
EFSM can help you to comply with safety regulations and industry standards.
Increased safety:
By identifying and fixing problems before they cause a failure, EFSM can help to improve the safety of your equipment.
Reduced downtime:
When problems are identified early, they can often be fixed without causing a major outage. This can save you time and money.
