Application
Measurement functions are 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
