Multilin N60

Network Stability and Synchrophasor Measaurement System

The N60 network stability and synchrophasor measurement system is a flexible device intended for the development of load shedding, remedial action, special protection schemes and wide area monitoring and control. Like no one device before, the N60 shares real-time operational data to remote N60s so the system can generate intelligent decisions to maintain power system operation.
