Voltage-Based
Protection
(Relay Models
SIMPRO-100-R or N-V)
When you purchase the SIMPRO-100 Relay with
optional voltage inputs, the relay enables a
number of additional protection functions. The
settings for these functions are described below.
4.6.1
Under- & Overvoltage
Elements
4.6.1.1
Phase-to-Phase Under- &
Overvoltage Elements
Table 4.28
Under- and Overvoltage Settings,
Phase-to-Phase Potentials
When you connect the SIMPRO-100 Relay
voltage inputs to phase-to-phase connected VTs,
as in Figure 2.7, page 30 or Figure 2.8, page 31,
the relay provides two levels of phase-to-phase
overvoltage and undervoltage elements. You may
use these elements for tripping, alarming, or
supervision of other conditions through the relay
programmable logic described in Appendix B,
page 137. To disable any of these elements, set
the pickup settings equal to OFF. The default
27P1P setting provides undervoltage supervision
for the underpower, reactive power, and power
factor tripping elements.
4.6.1.2
Phase-to-Neutral Under- &
Overvoltage Elements
Table 4.29
Under- and Overvoltage Settings,
Phase-to-Neutral Potentials
When you connect the SIMPRO-100 Relay
voltage inputs to phase-to-neutral connected VTs,
as in Figure 2.6, page 30 or Figure 2.9, page 31,
the relay provides two levels of phase-to-neutral
overvoltage and undervoltage elements, plus a
residual overvoltage element. The residual
overvoltage element operates using the phasor
sum of the three phase voltages and is hidden
and disabled if only a single phase-to-neutral VT
is connected to the relay. You may use these
elements for tripping, alarming, or supervision of
other conditions through the relay programmable
logic described in Appendix B, page 137. To
disable any of these elements, set the pickup
settings equal to OFF.
