| VT SUPERVISION | 46 | 01 | Sub-Heading | Sub-Heading |
| VT Supervision does not apply to P642 when the optional three-phase VT input is available. Only visible if Main VT is fitted or P642 model with 2 VT inputs. | ||||
| VTS Status | 46 | 02 | Indication | Blocking or Indication or Disabled |
| Determines whether on detection of
VTS. • VTS logic is Disabled. • VTS alarm is Indication only. • Voltage-dependent protection elements are Blocked. Optional conversion of directional overcurrent to non-directional protection (blocking mode only). |
||||
| VTS Reset Mode | 46 | 03 | Manual | Manual or Auto |
| VTS block is latched after
user-settable VTS Time Delay. Once latched, the reset methods are: Manual
using the front panel interface (or remote communications). Auto provided VTS condition has been removed and 3-phase voltages have been restored above ph |
||||
| VTS Time Delay | 46 | 04 | 5s | 1s to 10s step 0.1s |
| Operating time delay setting of the VTS element on detection of a voltage supervision condition. | ||||
| VTS I> Inhibit | 46 | 05 | 10 | 0.08pu to 32pu step 0.01pu |
| The overcurrent setting inhibits VT
supervision if all 3-phase voltages are lost, due to a close-up 3-phase fault
after CB is closed. In P643, CT1/CT2/CT3 if the VT is in the HV, TV or LV. In P645, CT1/CT3/CT5 if the VT is in HV, TV or LV. |
||||
| VTS I2> Inhibit | 46 | 06 | 0.05 | 0.05pu to 0.5pu step 0.01pu |
| NPS overcurrent setting inhibits VT
supervision if a fault occurs with excess negative sequence current. In P643,
always referred to CT1/CT2/CT3 if the VT is in the HV, TV or LV. In P645, always referred to CT1/CT3/CT5 if the VT is in HV, TV or LV. |

| Diff CTS | 46 | 21 | Enable | Enabled or Disabled |
| Enables or disables the CTS function | ||||
| CTS Status | 46 | 22 | Restrain | Indication or Restrain |
| In Indication mode, the CTS alarm is issued without delay when a CT failure is detected. In restrain mode, the differential protection is desensitised to the Is-CTS setting | ||||
| CTS Tdelay | 46 | 23 | 2s | 0s to 10s step 0.1s |
| Determines the operating time delay of the element on detection of a current transformer supervision condition | ||||

| Set release threshold | ||||
| CTS I2/I1>1 | 46 | 25 | 0.05 | 5% to 100% step 1% |
