VD23

Voltage Detector relay for transfer system

and safety

b At the leading edge of technology,

VD23 provides a presence of voltage relay

and an absence of voltage relay for all MV

network neutral systems.

VD23 is a compact voltage detection relay for MV networks voltage

from 3 kV to 36 kV, 50/60 Hz, efficient and self-adapted.

It is associated with a capacitive divider and a VPIS-VO.

b Self-adapted to the network voltage,

VD23 is ready to use.

b Skilfully designed, VD23 displays

the voltage (in % of the calibrated voltage).

b Adapted to various situation,

VD23 can be configured to work on different

combination of phase and unbalanced voltage.

b Compact and in DIN format,

VD23 fits naturally into MV cubicles.

b Fault current detection, facility can

be added by using Flair 23DV.

VD23

Voltage Detector relay for transfer system and safety

Voltage detection

VD23 detects a presence and absence of voltage, and activates 2 relays:

R1 = Presence of voltage

R2 = Absence of voltage.

The 2 functions are running simultaneously

Safety application and transfer application are independent

Combination of the function allows specific applications.

Absence of voltage

Calibration

Principle: at the VD23 power up, the voltage input is scanned, and as soon as it is

stabilised, the input voltage is memorised, and is considered as the nominal voltage.

Stabilisation time = 3 s

Other filtering

At any time, through the keyboard configurator a new calibration can be done.

Automatic calibration

Settings

By configuration (microswitches) the phase to take into account or the unbalanced

voltage can be chosen

Select the phase or phases voltage to be checked

Select to check the unbalanced voltage

Select to check phase to earth or phase to phase voltage.

For example:

3 phases and unbalanced: V1+V2+V3+V0

3 phases: V1+V2+V3, or U12+U13+U23

Single phase: V1, V2, V3, U12, U13 or U23

Unbalanced voltage only: V0.

Relay backup position

A switch allows choice of normal or inverse position for each relay.

It gives the relay position when power supply is down.

Time delay is configurable for each relay

On active position

On inactive position.

Thresholds are configurable (from keyboard) independently for both relays

Configuration in % of the voltage

Single voltage or unbalanced voltage.

Microswitches

6 microswitches are dedicated to define the logical

SW2 = calculation on phase to earth voltage or phase to phase voltage

SW3, SW4, SW5 = choice of the voltage to monitor

SW6 = monitor of the unbalanced voltage (only for phase to earth voltage)

SW1 = Inverse action. The Inverse action switches the logical relay output.

Example of settings

The table below shows the relays position upon the voltage status,

according to the phases defined to be checked by the microswitches position

V1 = Phase to earth voltage on line 1 is present

V1 = Phase to earth voltage on line 1 is absent

V1+V2 = V1 or V2 is present

V1.V2 = V1 and V2 are present.

Accessories

VD23 is fitted to a VPIS-VO adapted for the voltage measurement. The VPIS-VO,

is linked to the capacitor connected to the MV busbar, and delivers a voltage signal

on a specific connector. Various references of VPIS-VO allows adaptation to different

level of MV Voltage and MV capacitors values.
