17.1.2 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 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 operation and connection of instrument
transformers (CTs and VTs). During normal service by periodic comparison of the measured value
