VOLTAGE ELEMENTS
These protection elements can be used for a variety of applications such as:
•
Undervoltage Protection:
For voltage sensitive loads, such as induction motors, a drop in voltage increases the
drawn current which may cause dangerous overheating in the motor. The undervoltage protection feature can be used
to either cause a trip or generate an alarm when the voltage drops below a specified voltage setting for a specified time
delay.
•
Permissive Functions:
The undervoltage feature may be used to block the functioning of external devices by operat-
ing an output relay when the voltage falls below the specified voltage setting. The undervoltage feature may also be
used to block the functioning of other elements through the block feature of those elements.
•
Source Transfer Schemes:
In the event of an undervoltage, a transfer signal may be generated to transfer a load
from its normal source to a standby or emergency power source.
