Over/Undervoltage Elements
27TCk Undervoltage Element Torque Control
The 27TCk (k = 1–6) undervoltage element torque control uses a SELOGIC
control equation to provide torque control of the undervoltage elements. All
undervoltage elements are blocked from operation when the 27TCk input
evaluates to a zero. The default setting of 1 allows the undervoltage elements
to always operate.
27PkD1 Undervoltage Element Level 1 Delay
When the system voltage falls below the undervoltage setting value, the
undervoltage timer starts timing. Set the delay (in cycles) for which the timer
must run before the 27PkD1 (k = 1–6) setting asserts the output.
E59 Enable Overvoltage Elements
Use the E59 setting to enable the number of overvoltage elements you want to
use in the relay. Each overvoltage element provides two pickup setting levels.
59On Overvoltage Element Operating Quantity
Select the operating quantity 590n (n = 1–6) you want for each voltage
terminal from Table 3.113.
