The philosophy of electrical protection is continuously being relooked into with advancements of measurement, processing and communication technologies. Protection is being integrated with monitoring and control in a single package with value added facilities.
Large Thermal Power Stations as well as smaller Captive Power Stations require a complete range of protection relays for a variety of feeder, transformer and motor protection. Similarly, Power Transmission and Power Distribution requirerelays for substation automation.
While experienced users may conceive special schemes that require integration of features such as standard protection with special requirements such as islanding, bus transfer, load shedding, synchronization, SCADA interface and automation – implementation of such special schemes require integration of various discrete devices with associated complications.
Aartech works with its customers to understand their requirements, suggest value added features and facilities and provide standard as well as special custom designed protection schemes based on advanced programmable microprocessor based relays.
