Outline
The monitoring function is provided to measure the number of power quantities and statistics
data obtained within the VCT and BI circuits†. When the measuring instruments start
measures power quantities, mathematical means is applied to the data from the VCT so that
the data are shown accurately on the IED screen. The monitoring function has several screens
together. For current (I) and voltage (V) at rated input, the analog input data is measured with
±0.5% accuracy. For frequency, the data is measured with ±0.03% accuracy.
