3 - Voltage protections
List
The Voltage protections, available by default for Ekip Hi-Touch, Ekip G Touch, Ekip G-Hi Touch models and
configurable in the remaining models as additional SW package, are:
Name Type of protection Page
UV Minimum voltage 65
OV Maximum voltage 66
UV2
(1)
Minimum voltage 66
OV2
(1)
Maximum voltage 67
Phase Sequence Phase sequence error 67
VU Voltage unbalance 67
(1)
protections UV2 and OV2 are not available by default with Ekip G Touch. However, they can be
integrated by requesting the relative SW package
UV Protection
Function
The protection sends a TRIP command if one or more line-to-line voltages detected by the unit drop
below threshold U8 for longer than t8.
To check and simulate the trip times in relation to all the parameters, please consult:
• summary table of the protections with the operating characteristics (page 96)
• the graph with trip curve (page 105)
Parameters
Parameter Description Default
Enable
Activates/deactivates the protection and its availability in the
parameters menu
OFF
Trip Enable
Activates/deactivates transmission of the open command: if disabled,
the alarm and exceedance of protection time are only managed as
information
OFF
Threshold
U8
Establishes the value that activates the protection.
The value is given as both absolute value (Volts) and relative value (Un)
and can be set within the range: 0.05 Un to 1 Un in 0.001 Un steps
0,9 Un
Time t8
This is the trip time of the protection; the value is given in seconds
and can be set within a range: 0.05 s to 120 s, in 0.01 s steps
5 s
Limitations and additional functions
The block functions can also be accessed by means of the service connector (via Ekip Connect) or by
connection to the system bus (page 86).
