FAQs — Online Cable Condition Assessment
Q: What is Online Cable Condition Assessment?
A: It’s a method for assessing the condition of medium-voltage (MV) and high-voltage (HV) cables while they remain live (energised). EA Technology uses the CableData Collector™ (CDC) to detect and capture partial discharge (PD) activity — an early indicator of insulation degradation — without taking cables out of service.
Q: Why test cables while they are live?
A: Online assessment avoids outages and disruption to operations. PD information is gathered on actual operating cables, giving a real-world view of cable health and enabling proactive maintenance planning.
Q: What kinds of defects or issues can this identify?
A: The service detects and measures PD activity in single and three-phase cables, helping identify early signs of faults or insulation deterioration before failure occurs.
Q: How is the condition data analysed and reported?
A: After data is collected using the CDC, it’s transferred to analysis software and reviewed by experts. Clients receive a customised report with results, severity classification, and recommendations for follow-up actions.
Q: Does this service require downtime or cable shutdown?
A: No. One of the main benefits of online cable assessment is that it is quick, safe, and non-destructive — requiring no outage or shutdown of the cable system.
Q: What are the key benefits of online cable assessment?
A: It helps identify defects early, avoids unplanned outages or expensive reactive repairs, supports informed decision-making on remedial actions or replacements, and improves overall asset reliability.
