Network Automation Solutions 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.

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. Conforms to international standard CEI 62271-103 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 Conform to international standards CEI 62271-103 and CEI 62271-200 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 62271-111 Network Automation Ensto products overview Switchgear controllers 5 Controller for Air Break Switch ( 1 ) 6 Controller for Load Break Switch ( 2 ITI-A 3 ) 7 Controller for Auto-recloser ( 4 ) 8 Controller for Ring Main Unit ITI-S Type of network Overhead line Underground cable Switchgear compatibility 1 IA2T Air Break Switch 1 Auguste or Ergoswitch LBS 1 Smartcloser Auto-recloser Up to 8 switches Measure Current, voltage and power supply Current, voltage, power and power supply Fault detection Overcurrent Directional (ERDF configuration) Overcurrent ANSI 50, 51 Overcurrent Directional (ERDF configuration) Protocols IEC 60870-5-101 IEC 60870-5-104 Modbus RTU DNP3 HNZ (ERDF specification) Communication Digital or analog radio Dedicated Lines GSM GPRS Public Switch Telephone Network (PSTN) Ethernet External RTU In line with international standards Conforms to HN 64-S-44 specification In line with international standards Conforms to HN 64-S-44 specification Network Automation Ensto products overview Distributed generation Fault Passage Indicators 9 10 Operating Data Exchange System DEIE Type of network Underground cable Main features DEIE box is a control unit which manages the remote control and monitoring of decentralized generating facilities e.g. wind turbines, power plants etc. DEIE box allows information exchange and commands between network manager and independent producer.
