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 MAX-3 EHF):
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 MAX-3 EHF for detailed fault analysis, predictive maintenance, and scenarios where precision is paramount.
Yes, the TAURUS MAX-3 EHF is specifically designed to detect faults on double-circuit EHT (Extra High Tension) lines, even when one circuit remains energized. Here’s how it achieves this:
Innovative Testing Capability:
The MAX-3 EHF uses high-frequency injection and advanced signal processing to isolate faults on the de-energized circuit without interference from the live circuit.
This ensures accurate fault detection and localization, even in complex double-circuit configurations.
Key Features for Double-Circuit Lines:
Noise Immunity: The system is immune to electromagnetic interference (EMI) from the live circuit, ensuring reliable performance.
High Sensitivity: Detects faults with resistance up to 400 kΩ (upgradeable to 1.5 MΩ), making it suitable for high-resistance faults.
Fault Resolution: Pinpoints faults with an accuracy of +/- 100 meters over 1000 km, even in double-circuit setups.
Applications:
Maintenance Planning: Identifies faults and inhomogeneous points for targeted repairs.
Commissioning: Verifies the integrity of new double-circuit lines before energization.
Virtual Patrolling: Reduces the need for physical inspections, saving time and resources.
In summary, the TAURUS MAX-3 EHF is a versatile and reliable solution for fault detection on double-circuit lines, combining precision, noise immunity, and ease of use.
Minimized Downtime: Detecting faults on double-circuit lines without disrupting the live circuit ensures uninterrupted power supply.
Enhanced Safety: Accurate fault localization reduces the risk of equipment damage and operational hazards.
Improved Reliability: Ensures the stability and functionality of critical power transmission systems.
