EDS Expert Diagnostic System

EDS – Expert Diagnostic System – is an Overall Condition Moni­toring System designed to monitor the main substation assets: current transformer, voltage transformer, power transformers, circuit breakers, surge arresters and GIS switchgear, which integrates all the real time conditions from all relevant substation assets in a single system. EDS provides in one solution the monitoring of several assets, according to the requirements of each distribution, transmis­sion or generation application: Circuit Breakers (both AIS or GIS), Current Transformers, Voltage Transformers, Power Transform­ers (Bushing, Tap Changers, Tanks, Cooling System, DGA, alarms, etc), Surge Arresters, Batteries and other auxiliary assets, etc. The EDS is easy to install and, once configured, operates continuously. EDS units are designed to operate reliably under extreme weather conditions and electrical interference found in normal substation operations. In particular: Overall condition diagnostic system is designed to monitor the main substation assets: current transformer, voltage transformer, power transformers, circuit breakers, surge arresters and GIS switchgear. Reliable and accurate system to perform a Condition-based-Maintenance approach Easy to install and non intrusive, suitable also for existing substation Easy and user friendly interface to acquire and analyze data Modules mounted outdoor are IP 65 and designed to work over an extended temperature range (from – 40°C to + 85°C) Self-diagnostics continuously tracks the condition of the EDS and issues alerts if an abnormality is detected in the system By the continuous monitoring of the key parameters, EDS detects malfunctions in early stage and issues prioritized alarms communicating abnormal conditions and guiding maintenance decisions. EDS Condition Monitoring System is composed by several units; each one has dedicated electronic boards and sensors to per­form the requested measurements. The units are connected together through a bidirectional fiber optical loop. The HV loop is normally separated from the MV ones. A central unit collects all the data processed by the other Condi­tion Monitor Units through the optical fiber. In many cases, one of the remote unit could also be parameterized as central unit, in this case it has a dual function: remote and central unit. The configuration of the system could also be adapted by using slave units connected with remote units. The system is usually composed by: Central Unit – Data collation and computing Remote Unit for monitoring for all relevant assets EDS Condition Monitoring Software
