There are two parts of intelligent management system: OHL and substation equipment:
The monitoring and management complex for overhead line networks based on Lodestar
The system of equipping substations with telecontrolsystems and feeder monitoring devices withemergency processes localization functionality

Monitoring is a process of on-line continuous overhead lines control in order toobtain timely information about emergency and other processes occurring in the line
Online monitoring reduce your OPEX with automated, detection and analysis of troubles and accurate dispatch of crews
Complex monitoring implies obtaininginformation from various points of thenetwork from intelligent fault indicators
The management is performed bymeans of system retrofitting with remotelycontrolled switches and disconnectors

High-precision sensitive devices with power flow direction detection and eventidentificationThe usage of high-frequency sampling and fault currents and voltages values processingmakes possible to determine transient self-clearing faultsUnique algorithms of current and voltage valuesanalysis provide high sensitivity to an emergencyprocess, enabling to fix fault currents from 0.5 A
Lodestar – innovativemonitoring tools
А3Principle of Lodestars operation
Principle of Lodestars operation is based on sensing the fault current flowing inthe monitored line. The device is triggered upon the detection of a faultycurrent, above the current/time threshold
A current surge between the feeding substation andthe fault location followed by the line switch-offtakes place upon the manifestation of a fault
The path of the fault current from the feedingpoint to the fault location is shown by flashingLEDs and turned swivel. The fault is locatedbetween the last flashing and the firstinactive indicators
