Protection Functions
Over/Undervoltage Elements
59PkP1 Overvoltage Element Level 1 Pickup
Set pickup thresholds for the voltage values above which you want the Level 1
overvoltage elements to assert. The Level 1 pickup has a definite-time delay
(59PkD1) that can be used to provide a time delay on the assertion of the
overvoltage element.
59PkP2 Overvoltage Element Level 2 Pickup
Set pickup thresholds for the voltage values above which you want the Level 2
overvoltage elements to assert.
The 59PkP2 (k = 1–6) overvoltage element Level 2 pickup setting is typically
used for overvoltage tripping conditions. The setting is in secondary voltage.
The Level 2 pickup has no definite-time delay.
59TCk Overvoltage Element Torque Control
The 59TCk (k = 1–6) overvoltage element torque control uses a SELOGIC
control equation to provide torque control of the overvoltage elements. All
overvoltage elements are blocked from operation when the 59TCk input
evaluates to a zero. The default setting of 1 allows the overvoltage elements to
always operate.
59PkD1 Overvoltage Element Level 1 Delay
When the system voltage exceeds the overvoltage setting value, the
overvoltage timer starts timing. Set the delay (in cycles) for which the timer
must run before the 59PkD1 (k = 1–6) setting asserts the output.
