FAQs
The DIGITRACE DC 451P is an advanced version of the DC 361P, designed to handle more complex and demanding scenarios in power transmission and distribution systems. Here’s how they differ:
Detection Range:
DC 451P: Can detect faults up to 3 km (with optional configurations) and is upgradeable to detect faults with resistance up to 1.5 MΩ.
DC 361P: Detects faults up to 1 km (optional 3 km) with a sensitivity of up to 250 kΩ.
Sensitivity and Precision:
DC 451P: Offers higher sensitivity and can detect subtle faults even in extremely noisy environments. It also features automatic capacitance balancing for more accurate fault identification.
DC 361P: Provides excellent sensitivity but is better suited for standard applications.
Portability and Durability:
Both models are portable and housed in IP-protected Pelican casings, but the DC 451P is optimized for harsher environments with extended battery life and enhanced durability.
Applications:
DC 451P: Ideal for large-scale power stations and live switchyards up to 765 kV, where precision and extended range are critical.
DC 361P: Best suited for smaller systems and medium-scale applications.
In summary, the DC 451P is a more robust and versatile solution for complex, high-voltage environments, while the DC 361P is a reliable choice for standard applications.
Minimized Downtime: Detecting faults in live systems prevents unnecessary shutdowns, saving time and costs.
Enhanced Safety: Identifying faults in high-voltage environments reduces the risk of equipment damage and operational hazards.
Improved Reliability: Ensures the stability and functionality of critical power transmission systems.
