FAQs
Online Fault Detection:
How It Works: Online fault detection systems operate in real-time while the power transmission system is live. They are integrated with protective relay apparatus to quickly identify and isolate faults to prevent damage and ensure system stability.
Advantages:
Provides immediate fault detection and isolation, minimizing downtime.
Ideal for critical systems where uninterrupted operation is essential.
Limitations:
Prioritizes speed over precision, which can lead to less accurate fault localization.
May struggle with high-resistance faults or faults in noisy environments.
Offline Fault Detection (e.g., TAURUS APEX-D):
How It Works: Offline systems analyze the transmission line when it is de-energized. They use advanced techniques like multiple pulse echo correlation to pinpoint faults with high accuracy.
Advantages:
Offers unmatched precision, with fault resolution as tight as +/- 100 meters over 1000 km.
Enables predictive maintenance through line signature analysis, improving long-term reliability.
Can detect subtle faults (e.g., inhomogeneous points) that online systems might miss.
Limitations:
Requires the system to be taken offline temporarily, which may not be feasible in all scenarios.
When to Use Each:
Use online systems for real-time fault detection in critical, high-uptime environments.
Use offline systems like the TAURUS APEX-D for detailed fault analysis, predictive maintenance, and scenarios where precision is paramount.
