1 Network Automation Solutions

2 Answers to demands The current demographic growth and the continuous industrial development pose challenges for the current way of producing and distributing electricity. Energy suppliers must therefore produce more energy while optimizing distribution networks to satisfy their customers requirements of high quality service. Global solutions are necessary to reduce the duration and frequency of electricity outages. Ensto Network Automation solutions offer answers to these demands. Fast fault detection, automatic isolation of faulty network sections and remote network reconfiguration are essential part of network automation solutions. Electricity distribution performance index To evaluate their performance, electrical utility companies follow specific international indicators: SAIDI (System Average Interruption Duration Index) which measures the average cumulated power outage duration in minutes and per customer. SAIFI (System Average Interruption Frequency Index) which measures the average number of power outages per customer. Ensto s solutions are adaptable for every network globally to optimize electricity distribution.

Rated voltage: 24/36 kv Rated current: 630 A Breaking capacity: 630 A Rated voltage: 12/24 kv Rated current: 630 A Breaking capacity: 630 A Rated voltage: 38 kv Rated current: 630 A Breaking capacity: 12,5 ka Quenching media Air SF6 Vacuum Isolation media Air SF6 Epoxy Sectionalizing function Can be configured as a sectionalizer. Can automatically isolate the faulty section of the network after a programmed number of openings of an auto-recloser located upstream. Main features IA2T Air Break Switch responds to the service quality requirements in terms of reducing outage duration and frequency. Air Break Switch is installed on the main line after a feeder. It allows feeders to be divided into shorter sections to distribute loads or isolate a section of the network in case of outage. Remote control enables necessary operations for service continuity remotely. These load break switches are used in all types of overhead distribution networks in rural and suburban areas. Devices are available as manually or remotely controlled versions. They are designed to be easily integrated in remotely controlled SCADA systems. Modular design of the load break switches makes them adaptable to network constraints and different operating modes. Auguste and Ergoswitch load break switches suit many requirements: ensure service continuity fast and easy installation safe and reliable operation improve network cost-effectiveness Ensto Smartcloser is an intelligent autonomous device for detecting overcurrents, interrupting fault currents and re-energizing the line by automatic reclosing. If a fault is permanent the faulty section will be automatically isolated from the healthy part of the network. Ensto Smartcloser: long lifetime high level of electrical endurance convenient for all type of networks well suited for networks that require high breaking capacity extremely reliable safe for installers and end-users Conforms to international standard CEI Conform to international standards CEI and CEI Conforms to international standard CEI
