1.3 Important note
1.4 Labelling of the EIB Delta-
Meter (Example)
EIB Delta-Meters are intended solely for the measurement of electrical
energy.The installation and commissioning may only be carried out by
authorised electrical specialists.The appropriate norms, guidelines,
regulations and specifications should be observed when planning and setting
up electrical installations.
Advisory:
– EIB Delta-Meters should be protected from damp, dirt and damage during
transport, storage and operation.
– EIB Delta-Meters should not be operated outside the specified technical
data.
– Sufficient cooling for the EIB Delta-Meter must be allowed for.
Cleaning: If devices become dirty, they can be cleaned using a slightly damp
cloth and soap solution should a dry cloth not remove the dirt.
Corrosive materials or solutions should never be used.EIB Delta-
Meters should always be disconnected from the supply prior to
cleaning.
Maintenance: EIB Delta-Meters are maintenance-free.No repairs should be
carried out if damage occurs (e.g. during transport or storage).
The warranty expires if the EIB Delta-Meter is opened.

The EIB Delta-Meters are suitable for installation in distribution boards
or small enclosures, for wall mounting or panel mounting.They can be
snapped onto 35 mm mounting rails, according to DIN EN 50 022.
Connection: The electrical connection is carried out via screw terminals.
The terminal markings and insulation strip lengths are embossed in the
terminal area of the meter.(Wiring diagrams can be found in section 5.3).
The connecting screws should be tightened using the following torque:
Main terminal:
– Direct connected meter (M5 screw) 2.0 Nm
– Transformer rated meter (M4 screw) 1.2 Nm
When connecting aluminium conductors, the contact surfaces of the
conductors should be cleaned, brushed and greased.The connecting
terminals should be re-tightened after approx. 6 to 8 weeks.
Maintenance procedures can be simplified by using external terminal blocks
when connecting a transformer.
Fuse protection: The voltage circuit should be protected by a series-
connected,
miniature circuit-breaker, in order to prevent the meter from being
damaged in the event of a short circuit or overload.
– Direct connected meter max. 65 A (63 A)
– Transformer rated meter max. 6 A
Seal: To protect the EIB Delta-Meter from being tampered with after
installation and programming, it is possible to seal the device at four points.

Various measurement methods are used in the EIB Delta-Meters depending
on the type of meter.The following equations are vector equations.
Measurement method with one measuring element
This method only produces the correct result if the phase load is symmetrical.
P = 3 · IL3 · UL3
This method is not suitable for carrying out
accurate measurements in polyphase
voltage networks as 100% symmetrical
loading seldom occurs.
Measurement method with two measuring elements
This method is used in polyphase voltage networks without a neutral
conductor (three-wire network) with symmetrical or asymmetrical loading.
P=U
L1 · IL1 + UL2 · IL2 + UL3 · IL3
ΣI=I
L1 + IL2 + IL3 = 0
P = UL1 · IL1 - UL2 (IL1+ IL3) + UL3 · IL3
P = IL1(UL1 - L2) + IL3(UL3 - L2)
This method (with 2 measuring elements) is not suitable for carrying out
accurate measurements in networks with inductive or capacitive loads with a
low cos ϕ. In this case, the method that uses 3 measuring elements should
be selected.
Measurement method with three measuring elements
This method is used in polyphase voltage networks with a neutral conductor
(four-wire network).It can however also be used in networks without a
neutral conductor, provided that an artificial neutral point is created.
P = UL1 · IL1 + UL2 · IL2 + UL3 · IL3
This method is very accurate, even in the
case of asymmetrical loads and low cos ϕ.

Active and reactive power: Capacitive or inductive loads cause a phase
angle shift between the phase current and phase voltage.
The maximum permitted phase angle shift is often contractually defined by
the power supply companies. So that the specified values are not exceeded,
power factor correction systems are often installed and the consumption is
monitored using reactive energy meters or combination meters.
So that energy consumption can be measured in installations with current and
voltage levels beyond the nominal measuring range of the EIB Delta-Meter, it is
necessary to use current and/or voltage transformers.It is important that the
secondary current and voltage of the measurement transformers, lie within the
permitted measuring ranges of the transformer rated meter. In order to
guarantee the required level of accuracy, the selected transformers should
have a higher accuracy class than the meter.The current transformers must be
connected with the correct polarity (K1 ⇒ L1, k1 ⇒ l1).
Note: The secondary measuring circuits of the transformers must be laid
separately to the main power cables to eliminate induced current errors.
The terminal block indicated above is not absolutely necessary for the
installation but simplifies servicing procedures.

Power consumption of the secondary measuring circuits: If current
transformers are to be connected to an EIB Delta-Meter, it is necessary to
consider the power consumption of the entire secondary measuring circuits
when selecting the current transformers, so that accurate measured values
are achieved.The nominal power of the current transformer (Ssec) must be
selected according to the power loss of the connected meter and the power
loss of the secondary measuring circuits.
The following applies:
Ssec ≥Scable + Smeter S = Apparent power (VA)
The table of recommended values below represents the power consumption
of the cable (Scable) as a function of the cable length and cross section.

Energy summation: If the energy of several loads is to be measured using
a single electricity meter connected to more than one current transformer per
phase, the individual lines that are assigned to the current transformer must
be operated in parallel.All current transformers used must have the same
transformer ratio.The total of all the currents may not exceed 6 A.
In the example shown (three-wire network), the meter measures the total
energy consumption of cable 1 and cable 2.The type of load (asymmetrical
or symmetrical) is not significant in this case.
The same application is possible in a four-wire network. Current transformers
must then be operated in L1, L2, L3.The current transformers must be
connected with the correct polarity (K1
⇒ L1, k1 ⇒ l1).
