18.1.2 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 from the IED with other independent meters the proper
operation of the IED analog measurement chain can be verified. Finally, it can be used to verify
proper direction orientation for distance or directional overcurrent protection function.
