PLDS-based divider automation system monitors short-circuit currents flowing through the transmission line network, localizes the damaged section and gives a command for switching on automatic reserve entry. The system is based on PLDS: Overhead Power Line Diagnostics System (PLDS) is designed to remotely monitor the state of the wire without need for on-site visits by service personnel, and it signals the possibility of emergency situations in the early stages. The system tracks the following parameters: - wire operating parameters: temperature, current, sag angle, vibration amplitude and frequency; - the occurrance, magnitude, and direction of short circuit current (with event oscillogram capture); - ice load with weight display in kg; wire sag in meters (over roads, crossing, water bodies, etc.); - wire break within the anchor section; - wind loads on the wire, conductor galloping; - detection of short circuit; - prevention of wire breakage due to ice deposit formation; - DLR; - control of wire temperature, sag angle and distance between wire and obstacle.
