Main Features and Advantages

Advanced Fault Detection: The ALSTOM EPSD-0603 DFI-150-0003 utilizes sophisticated algorithms to distinguish between actual faults and transient disturbances with ±1% accuracy. Its directional sensing capability identifies fault direction, reducing outage times by up to 70% through precise fault location identification.

Self-Powered Operation: Utilizing innovative current transformer technology, the device harvests energy directly from the conductor it monitors. This eliminates external power requirements while maintaining continuous monitoring capability even during outages. The lithium battery backup ensures operation during zero-current conditions.

DFI-150-0003

Robust Environmental Protection: Designed for harsh outdoor environments, the ALSTOM EPSD-0603 DFI-150-0003 features IP68-rated encapsulation that withstands extreme temperatures (-40°C to +85°C), UV exposure, and moisture ingress. The corrosion-resistant stainless steel clamp ensures reliable performance in coastal and industrial areas.

Wireless Communication Network: Integrated RF transceiver enables automatic mesh networking with neighboring indicators. Fault data propagates through the network to central systems within seconds, providing comprehensive feeder section visibility without additional communication infrastructure.

Visual Status Indication: High-intensity LED indicators provide immediate visual fault confirmation from ground level. The tri-color system displays pre-fault conditions (green), fault detection (red), and communication status (blue), enabling rapid crew response during outages.
