Criterion - Measuring Method
For all protection elements it can be determined, whether the measurement is done on basis of the » Fundamental« or if
» True RMS« measurement is used.
Dropout Ratio
The dropout ratio is settable.
If phase voltages are applied to the measuring inputs of the device and field parameter
»Main VT con« is set to »Wye« , the messages issued by the voltage protection module in
case of actuation or trip should be interpreted as follows:
»59M[1].P A« or »59M[1].T
ICKUP
»59M[1].P B« or »59M[1].T
ICKUP
»59M[1].P C« or »59M[1].T
ICKUP
However,if line-to-line voltages are applied to the measuring inputs and field parameter
»Main VT con« is set to »Wye« , then the messages should be interpreted as follows:
»59M[1].P A« or »59M[1].T
ICKUP
»VAB« .
»59M[1]. P B« or »59M[1].T
ICKUP
»VBC« .
»59M[1]. P C« or »59M[1].T
ICKUP
»VCA«
