This brand new product has been developed thanks to the vast knowledge and experience gained in the field over the last 70 years.
EDS – Expert Diagnostic System is the on line continuous diagnostic system for substation apparatus and is suitable to monitor the condition of:
• High Voltage and Medium Voltage Circuit Breakers (CB)
• Current and Voltage Transformers (CT’s/ VT’s)
• High Voltage Surge Arrestors (MOV’s)
EDS has been designed and tested in full compliance with the highest international standards and it represents a real revolutionary diagnostic system for substation apparatus operating continuously, even under extreme weather conditions, and guiding maintenance decisions.
 

The Traveling Wave Fault Location System TFS 2100 provides accurate fault location solution for transmission and distribution power lines.
The TFS 2100 traveling wave fault locator, determines distance to fault by measuring the time for a surge to travel from fault position to measurement point. The fault distance measurement error is less than ±150m typical regardless of the line length.
The TFS 2100 consists of Traveling Wave Data Acquisition Unit TDU 100 installed in substations, a Master Station Software deployed in the control center and communication network. Each TDU 100 can monitor up to 4 lines, hence when more than one TDU 100 is installed in a substation, a Data Processing Server DPS 100 is used to collect traveling wave data acquisition units and communicate with the Master Station.
 

ISA testing systems can collect, store and analyze data by TDMS, test & data management software, which is supplied to every ISA power test equipments. TDMS is continuously updated by our software engineers in order to provide the highest excellence and accuracy while measuring and testing.
The software can be upgraded free of charge by logging in the software download area available on our web site for all ISA customers.
