Smart Navigator 2.0 HV

Overview

Shahig Smart Navigator 2.0 HV is an overhead-line short-circuit indicator designed to reduce outage times through intelligent fault detection and network condition monitoring.

Key Features

• Intelligent overcurrent-based fault detection with adaptable parameters
• Overhead line monitoring data for network condition evaluation
• Energy harvesting power supply from overhead line current (operation from low load current)
• Remote maintenance: configuration and software updates from the control room
• Installation on live conductors using a hot stick (from the ground)

Applications

• Overhead MV distribution networks
• Fault location and service restoration programs
• Utilities aiming to reduce SAIDI/SAIFI through faster fault sectioning
