3.12 Undervoltage Protection
3.12.1 Undervoltage Protection Theory
This relay provides a two-stage undervoltage protection with definite time delay characteristics.
The two stages have same protection logics. Each stage can be used for tripping or alarming
through the PCS-Explorer and the default is for tripping.
This protection can support all kinds of VT connection: three phase voltage (Ua, Ub, Uc), three
phase-to-phase voltages (Uab, Ubc, Uca), two phase-to-phase voltages (Uab, Ubc), anyone of
three phase voltages or anyone of three phase-to-phase voltages.
Two methods are used to check the undervoltage condition by the setting [27P.Opt_1P/3P]. If
setting [27P.Opt_1P/3P] is set as
“0”, and all of the three voltage values are less than the voltage
setting, the undervoltage protection will operates after the appointed time delay; and if the setting
[27P.Opt_1P/3P] is set as
“1”, and anyone of the three voltage values is less than the voltage
setting, the undervoltage protection will operates after the appointed time delay.
The setting [27P.Opt_Up/Upp] is used to decide the voltage input mode. If it is set as
“1”, the input
voltage is phase-to-phase voltage; and if it is set as
“0”, the input voltage is phase voltage. So the
