Function
The phase Sequence protection trips when the sequence of the voltages is not aligned with the sequence
set by the user.
Parameters
The following is a description of the parameters in the various menus:
Parameter Description
Enable To activate/deactivate the protection.
Threshold It defines the voltage control sequence.
Main page - Menus - Advanced - Alarms
Function
The protection Cos φ trips when the total cos φ value drops below the threshold set.
NOTE: total cos φ is calculated as the ratio between Total active power and Total apparent
power.
Parameters
Here is a list of the available parameters:
Parameter Description
Enable To activate/deactivate the protection.
It defines the value of cos φ below which the protection is activated.
Threshold
Main page - Menu - Advanced
Function
The Synchrocheck module recognizes and signals if the synchronism conditions exist between two
independent voltage sources (example: generator + network) for closing of the interconnection circuit-breaker.
NOTE:
• Synchrocheck functions are activated only if the Ekip Synchrocheck module is present.
• All the operating specifications are described in the paragraph that describes the Synchrocheck
module, on page 185.
