Application
Measurement functions is used for power system measurement, supervision and reporting
to the local HMI, monitoring tool within PCM600 or to station level for example, via IEC
61850. The possibility to continuously monitor measured values of active power, reactive
power, currents, voltages, frequency, power factor etc. is vital for efficient production,
transmission and distribution of electrical energy. It provides to the system operator fast
and easy overview of the present status of the power system. Additionally, it can be used
during testing and commissioning of protection and control IEDs in order to verify proper
