MENU TEXT
Setting that determines the operating time-delay of the element upon detection of a voltage supervision condition.
VTS I> Inhibit
The setting is used to override a voltage supervision block in the event of a phase fault occurring on the system that could trigger the
voltage supervision logic.
VTS I2> Inhibit
The setting is used to override a voltage supervision block in the event of a fault occurring on the system with negative sequence current
above this setting which could trigger the voltage supervision logic.
Inrush Detection
This setting is to enable/disable the Inrush Detection used for the Distance protection.
Inrush Detection
This setting is to enable/disable the Inrush Detection used for the Distance protection if Phase Differential Protection is disabled or set
Compensation is not set to Transformer.
I>2nd Harmonic
If the level of second harmonic in any phase current or neutral current exceeds the setting, inrush conditions will be recognized by changing
the status of four DDB signals from low to high in the Programmable Scheme Logic (PSL). The user then has a choice to use them further in
the PSL in accordance with the application.

CTS Mode
Setting to disable, enable the standard (voltage dependant) CTS element
CTS Mode
Setting to disable or enable the Differential (current based, communication dependant) CTS
CTS Mode
Setting to disable, enable the standard (voltage dependant) CTS or enable the Differential (current based, communication dependant) CTS or
allow both CTS algorithms to work simultaneously
CTS Status
This setting determines whether the following operations will occur upon detection of CTS.
• CTS set to provide alarm indication only.
• CTS set to restrain local protection
The settings are visible if CTS Mode is not disabled.
