Technical data sheet MV network management - Easergy range VD23 Voltage Detector relay for transfer system and safety b Self-adapted to the network voltage, VD23 is ready to use. 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. PE57787 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. 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. Applications b Applications based on presence of voltage The loss of voltage activates a change of state of the R1 relay v Automatic transfer systems v Alarms on voltage loss v Automation on loss of voltage. b Application based on absence of voltage v Earth locking on presence on voltage v Alarms on voltage presence. Reference EMS58421 VD23 Voltage Detector relay for transfer system and safety Voltage detection Presence of voltage detection b VD23 detects a presence and absence of voltage, and activates 2 relays: v R1 = Presence of voltage v R2 = Absence of voltage. Absence of voltage detection b The 2 functions are running simultaneously v Safety application and transfer application are independent v Combination of the function allows specific applications. Calibration b 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. v Stabilisation time = 3 s v Other filtering v At any time, through the keyboard configurator a new calibration can be done. Automatic calibration Settings b By configuration (microswitches) the phase to take into account or the unbalanced voltage can be chosen v Select the phase or phases voltage to be checked v Select to check the unbalanced voltage v Select to check phase to earth or phase to phase voltage. Flexibility For example: v 3 phases and unbalanced: V1+V2+V3+V0 v 3 phases: V1+V2+V3, or U12+U13+U23 v Single phase: V1, V2, V3, U12, U13 or U23 v Unbalanced voltage only: V0. b Relay backup position v A switch allows choice of normal or inverse position for each relay. It gives the relay position when power supply is down. b Time delay is configurable for each relay v On active position v On inactive position. b Thresholds are configurable (from keyboard) independently for both relays v Configuration in % of the voltage v Single voltage or unbalanced voltage.
