9.3.5 Voltage protection
9.3.5.1
Overview
For Voltage protection there are settings for Under-voltage, Over-voltage, Residual over-
voltage and Overexcitation protection. There are three instances of parameters in each
category except in the case of Overexcitation which has two instances. Each instance
consists of a number of parameters that make it possible to switch the function On or
Off, set rated quantities or make other adjustments necessary for the fine tuning of the
function itself.
9.3.5.2 Loss of voltage check LOVPTUV (27)
Main menu/Setting/Setting Group N/Voltage protection/LossOfVoltage(PTUV,27)/
LOV
Parameters for voltages and timers are set here.
9.3.5.3 Overexcitation protection OEXPVPH (24)
Main menu/Settings/Setting Group N/Voltage protection/Overexcitation(PVPH,
24)/OEX1
Displays settable parameters for operation, rated current and voltage, time delays for
user designed curves and several other related settings.
9.3.5.4 Two step overvoltage protection OV2PTOV (59)
Main menu/Settings/Setting Group N/Voltage protection/
OverVoltage2Step(PTOV,59)/TOV
Displays several settable parameters including settings for Time Overvoltage Curves
(TOC) and other function related settings.
9.3.5.5 Two step residual overvoltage protection ROV2PTOV (59N)
Main menu/Settings/Setting Group N/Voltage protection/
ResidualOverVoltage2Step(PTOV,59N)/TRV
Displays up to several settable parameters for characteristics and many related
parameters.
