2. Applicability and characteristics
VD4 Digital Instructions:
The VD4 Digital circuit-breaker is based on the VD4
version. So much so, most of the information in the
VD4 instruction manual is also applicable to the VD4
Digital circuit-breaker.
Please refer to the instruction manual of the VD4
circuit-breaker (code 647654) for specific
information.
Additional information concerning the VD4 Digital
circuit-breaker is given in this supplement.

Combined current-voltage sensors
The current is measured by a Rogowski coil: a
uniform winding on a closed circular support with a
constant crosssection and without a ferromagnetic
core. The voltage induced in the winding is directly
proportional to the variation in the let-through
current.
The current sensors are characterized by the
absence of saturation and hysteresis phenomena
and by their accurate measurement for fault
currents up to the maximum adjustable setting
value of the protection thresholds.
The voltage is measured by a capacitive divider: a
cylindrical metal electrode moulded in the sensor
and facing the circuitbreaker bushing. The output
signal is a voltage directly proportional to the
primary voltage.
The voltage sensors are characterized by the
absence of ferroresonance phenomena.
General
VD4 Digital circuit breaker with embedded sensors
and a new relay, for instance type REF 615, has been
designed to provide a powerful electrical plant
protection system.
VD4 Digital circuit-breaker uses current sensors or
combined current and voltage sensors
(combisensors) able to measure the current and
voltage applied to each pole.
The VD4 Digital circuit-breaker is available in
withdrawable version for UniGear ZS1 switchgear,
PowerCube units, and OneFit. It can be used in fixed
version for the design and supply of roll-in-retrofit
solutions to MV circuit breaker installed base, in
particular when original circuit breaker had current
or voltage instrument transformers or direct acting
relay mounted on withdrawable truck.
VD4 Digital is mechanically interchangeable with the
VD4 series circuit-breaker.

5. Specific characteristics of the product
Current and voltage sensors
Two types of sensor can be used in VD4 Digital
circuit-breakers:
• Rogowski coil: for current measurement only.
• Combisensors: allow both current and voltage
measurements. Along with the Rogowski coil, they
have an integrated capacitive divider for
measuring the voltage applied during each phase.
This new generation of sensors is small, provides a
better performance than conventional current and
voltage transformers and possess a higher degree
of standardization.

Schematic diagram of the Rogowski coil (current sensor).
Combined current voltage sensor applied to the circuit-breaker poles.
The Rogowski coil
This consists of a uniform winding over a closed
circular support with a constant section and
without a ferromagnetic core.
The voltage generated in the winding is directly
proportional to the derivative of the let-through
current.
There are many advantages in using the Rogowski
coil, amongst which are:
• absolute linearity of the outgoing signal
• no saturation
• no currents able to magnetize the metal core. This
is very important at low current values for current
transformers
• no hysteresis phenomena.
During the design stage of the VD4 Digital circuit-
breaker, the characteristics described above made it
possible to adopt the solution with only three
sensor sizes, which can cover all rated current values
from 50 to 2500 A and guarantee protection against
short-circuits up to 40 kA.
Rogowski current sensors is constant and does not
depend on the primary current value. This means
that the error can be eliminated with an appropriate
characteristic correction factor of the sensor.
Conventional current transformers have an error
that depends on the primary current, so the error is
not constant and cannot be corrected. Moreover, it
takes on considerable values at the ends of the
primary current field.

Types and characteristics of the sensors used in the
VD4 Digital circuit-breaker
VD4 Digital circuit-breakers, which do not include
voltage measurement, use KEVCR AC1, KEVCR BC1
and KEVCR CC1 current sensors with rated currents
of 1250, 2000 and 2500A respectively. KEVCR AA1,
KEVCR BA1 and KEVCR CA1 type sensors are used
for the VD4 Digital with voltage measurement, with
rated currents of 1000, 1800 and 2300A respectively.

The capacitive element consists of a cylindrical

The output signal is a voltage directly proportional

The voltage sensors are characterized by the
absence of ferroresonance. Just a single capacitive
divider covers the operating voltage range through

6. Installation
Connection to the IED
The sensor cable is terminated by shielded RJ-45
plug connector that shall be connected to the inputs
of the IED. A label identifies each phase connector,
the names -XDB 411, -XDB 412, -XDB 413 are used for
L1, L2, L3 phases respectively.
The sensor plug connector pin’s assignment is
shown below (front view):
Sensor wires are connected according to the
following assignment:
Rogowski sensor:
4 - Coil start
5 - Coil end
Voltage sensor:
7 - Cap. electrode
8 - Ground
This secondary cable is a special shielded cable
designed to give maximum EMI shielding. The cable
shall be connected directly (or via a connector
adapter if needed) to Intelligent Electronic Device
(e.g. protection relay). The electrical shielding of
cable is connected to connector shielding and shall
be earthed on IED side. The cable cannot be moved
if the temperature is below 0 °C. If cable, connector
or connector grommet is damaged please contact
the manufacturer for instructions.
Note for retrofit applications:
It is recommended to use a cable tie to fasten long
sensor cables approximately 10 cm from the RJ-45
socket. A cable not connected to the IED can be left
open or short-circuited without any harm for the
sensor. Even during a primary short-circuit the
voltage in the secondary circuit of the current
sensor will be below 100 V. Nevertheless it is a good
safety practice to earth cables not connected to the
IED.RJ-45 plug connector has 8 contacts and locking
latch coupling. The sensor connector plug shall be
inserted properly with the IED matting receptacle
before completing the coupling with the bayonet
lock. Take care and do not use excessive force to
plug-in and plug-out these connectors.The used RJ-
45-type connectors (EIA/TIA 568A Standard) are
screened and designed to guarantee low resistance
shielding; they are particularly adapted to
applications where electromagnetic compatibility
(EMC) is important. The connectors are robust but it
is necessary to be careful during their assembly – do
not use force.
Instructions for use
Rated parameters
Because the sensors are highly linear within a very
wide range of currents and voltages, the same
single sensor can be used for the various rated
currents and voltages associated with each specific
application. There is no need to specify other
parameters such as burden, safety factor etc. since
they are standard over the defined range. To achieve
the correct function of the protection and control
IED, the selected rated current, as well as the rated
transformation ratio, must be programmed into it.
DANGER
THE SENSORS ARE USED:
• To convert large currents and voltages in the
primary circuit of the network to the
appropriate signal for the secondary
equipment (e.g. IEDs)
• To insulate primary and secondary circuits
from each other
• To protect secondary equipments from
harmful effects or large currents during
abnormal situations in the network
THE USE OF A SENSOR FOR OTHER PURPOSES
THAN THOSE DESCRIBED ABOVE IS
FORBIDDEN.

VD4 DIGITAL ADDENDUM - TO VD4 INSTALLATION AND SERVICE INSTRUCTIONS
Correction factors
The amplitude and phase error of a current and a
voltage sensor is, in practice, constant and
independent of the primary current and primary
voltage. Hence, it can be corrected in the IED by
using appropriate correction factors, stated
separately for every sensor. In addition with VD4
Digital the length of the wiring harness is
compensated.
The use correction factor for amplitude error is
required condition in order to achieve the declared
accuracy class, as below described:
Current sensors: value of amplitude correction (al)
factor to be set in the relay = Corr.f.I marked on the
label shall be multiplied for 1.0007.
e.g. value of amplitude correction factor, according
to the label on image below:
0.9999 x 1.0007 = 1.0006
Voltage sensors: value of amplitude correction (al)
factor to be set in the relay = Corr.f.V marked on the
label shall be multiplied for 1.0048.
e.g. value of amplitude correction factor, according
to the label on image below:
0.9999 x 1.0048 = 1.0047
