the preferred current
connection for power meters is
the power meter direct current
input. Up to 50Arms this is no
problem but higher currents
generate much heat in the
internal shunt, making the
measurement inaccurate, due
to temperature drift.

External current
sensors
For higher currents the only
solution is to make use of external
current sensors. Current sensors
are widely available, but current
sensors for accurate energy and
power measurements are scare. A
current sensor for electrical power
measurements needs to have
specifications for its internal phase
shifts at different frequencies.

SenSor TYPeS
MaCC plus - external current sensor
This is the most popular current sensor available, with a
1000:1 current transfer ratio for maximal 850Apk (600Arms).
In case of DC currents, max. 600Adc can be measured
continuously. Also types with voltage outputs are available;
■ 100Apk/10Vpk and 200Apk/10Vpk & 500Apk/10Vpk.
■ With overload capacity of 20%, sinusoidal currents can be
measured of respectively 85Arms, 170Arms and 430Arms.
■ Maximum continuous DC currents are the same as the ACpeak
limits.
Can be used with the junction unit HUB4MACC to minimize
wiring. The “current-in/current-out” type has preference over the
“current in/voltage out” type, mainly because of better noise
behaviour of the signals between the junction unit and the low
impedance of the power meter current shunt.
SC1000 - Split Core zero-flux TM current measuring
system
Often it is not possible or allowed to switch-off a motor used
in a production facility or in a critical safety environment like
a nuclear power plant. Also it can be inconvenient and costly
to remove and replace eyelets of thick power cables in order
to run them through the sensor hole. The new SC1000 high
precision split-core current sensor solves these issues.
■ Measures primary currents up to 1000Apk (700Arms).
■ Transfer ratio is 1000Apk/0.5Apk or 1000Apk/10Vpk in
case of a voltage output.
■ The SC1000 can be used with the junction unit
HUB4MACC to minimize wiring.
CuraCC - zero-flux TM current measuring system
If 1000Apk (700Arms) is not enough, then there is the
CURACC-series, up to 6000Apk (4240Arms) for “current-in
current-out”. Up to and including 2000Apk (1400Arms) we
advise the head model B encapsulated, a resin encapsulated
head that is more robust for industry applications. Between
2000Apk (1400Arms) and 6000Apk (4240Arms) the head
model E with side plates is advised for easy mounting and
robustness.
■ Output current always 1Apk at the primary peak current
level as defined by the customer.
■ In case of DC currents, max. 2000Adc (model B) resp.
6000Adc (model E) can be measured continuously.
■ Can be used with the junction unit SUM3 or SUM4 to
minimize wiring.
for every application there is a solution. please contact your local
Yokogawa or hitec representative if you have even more demanding
applications.
The input current producing the specified output signal (1A or 10V) can be chosen between
±150Apk and ±6000Apk.
Example: A CURACC ordered with a transfer ratio 500A/1A can measure currents from -500Apk
to +500Apk, producing -1Apk to +1Apk at the output.

why an external Zeroflux
tm current sensor?
To maintain the unique features of
the Yokogawa power meters, such
as measuring accurately current
and power from DC up to several
kHz, it is necessary to connect
special current sensors with the same
features. This is of great importance
for measuring conversion efficiency
in situations where DC power is
converted to AC power as for solar
power or variable frequency drives.
temPerature & Phase shift
The normal connection for measuring
current with power meters is the
“direct current input”, which consists
of a special resistor with very good
AC properties, the shunt. Up to
50Arms for Yokogawa’s WT1600
(33Arms for WT3000) is no
problem. Higher currents however
generate too much heat in this shunt
to maintain accurate measurements
due to temperature drift.
For this reason, measuring higher
currents requires external current
sensors. Current sensors (most for
50–60Hz only) are widely available,
but current sensors for accurate
energy and power measurements are
scarce. A current sensor for electrical
power measurements needs to have
specifications, not only for its transfer
ratio, but also for its internal phase shifts
at several frequencies and it’s stability.
ct anD Dcct
Conventional AC measurement
Current Transformers (CT’s) lack the
capability to measure current at low
frequencies (for example 5Hz, as
found in frequency inverter drives).
DC current will not be transformed
at all, as it saturates the transformer.
8
Output
AC with some DC might saturate a
conventional transformer, or at least
strongly distort the current shape.
The Hitec Direct-Current Current
Transformer (DCCT), based on
the Zero-flux TM principle, is able
to measure currents in a wide
bandwidth from DC to several kHz
with a very high accuracy.
Hitec DCCT’s eliminate measuring
errors which may arise with
conventional AC-sensors.
Galvanic isolation
More and more users in the Industry
start to appreciate the performance
of the Hitec Zero-flux TM CT’s for
precise current measurements related
to electrical power and energy. A
Zero-flux TM CT consists of a special
multi-core toroidal measuring head
and an electronics module. The
high accuracy and stability of the
Hitec Zero-flux TM CT is based on
the Zero-flux TM principle that actively
maintains a perfect balance between
the magnetic fields of the primary
and secondary windings down to
the parts-per-million (ppm) level. The
Zero-flux TM CT sensors are galvanic
isolated from the primary circuits,
similar to conventional AC-current
transformers.
Powerloss Dc-comPonent
As most AC clamps and sensors
today ignore DC current by not being
able to measure DC, the Zero-flux TM
CT measures the true wave shape,
including the DC component. This
is a great improvement for PWM
inverters measurements, where any
DC component at the output creates
a power-loss in the drive and motor
windings and therefore should be
measured.

extreme high accuracy: 0,1% of a 1 GW transformer
ct Current transmission. Shown here are the three-phase
tion in Eemshaven (NL) with a total power transmission
accuracy
The accuracy of the Hitec Zero-flux TM
CT sensors matches perfectly with
the high accuracy of the power
meters from Yokogawa. The typical
accuracy of a Zero-flux TM CT with a
closed type sensor head is 0.01%
of the rated current (50Hz). Closed
AC/DC-type sensors equipped with
Hall-elements do have an uncertainty
of approximately 0.1% of the rated
current.
sPlit-core
A disadvantage in using closed type
current sensors is that the primary
conductors temporarily have to be
disconnected from the load. The
load has to be switched off, eyelets
of the cable connection need to
be replaced if they don’t fit through
the sensor hole etc. This is not
always allowed and at least timeconsuming,
inconvenient and costly.
Often it requires the assistance of an
installation engineer
Therefore Hitec developed the
SC1000 high precision split-core
Zero-flux TM CT, with an overall
accuracy of 0.1% of the rated current
(for DC and AC), where
as traditional clamp type
accuracy normally starts
with a 1% uncertainty.
The SC1000 reduces the
measurement uncertainty
on a 4 MW motor/
generator from 40 kW to
4kW.
multi-Phase anD easy
connection
The Hitec current sensors can be
delivered as a single unit to measure
single-phase current or as a multiphase
system with 3 or 4 Zero-flux TM
CT’s together with a junction unit,
powering all Zero-flux TM CT’s. The
junction unit interconnects the current
sensors and directs all measuring
signals to one output connector to
which the Yokogawa power meter is
connected.
In case of multiple primary cables per
phase (power generators, distribution
transformers etc.) it is even possible to
parallel the Zero-flux TM current sensors
to measure higher currents.
The standard cable length between
the sensor head and the junction unit
is 3 meter. Up to 50 meter of cable
length is possible on request, more
than 50 meter, depends on the local
noise environment.
The same flexibility applies for the
cable length between the junction
unit and power meter.

large HaDron ColliDer aT Cern,
SwiTzerlanD
The first manufacturer
The Zero-flux TM principle is by
far the best way to measure
Direct Currents. Galvanic
separation, extremely high
accuracy and stability are
the foremost advantages of
this principle. The Zero-flux TM
principle was already known at
the turn of the 20th century, but
was never put into practice.
It found its revival in the mid
sixties when a scientist at
Cern in Geneva, developed
techniques to use it for very
accurate measurements of
current. Soon a commercial
version became available for
general use when Hitec Power
Protection became the first to
manufacture a product based
on this zero-flux principle.

The Zero-flux TM
current sensors
the Zero-flux tm current sensors are
well-liked in high-energy physics
research centers for rectification
systems supplying the current
that generate the magnetic fields
for the focusing and deflection
of elementary particles or for the
containment of plasma.

Basic diagram of a Zero-flux TM
CT with voltage output
the basic PrinciPle
The primary current Ip generates a magnetic flux that
will be counteracted by the current Is in the secondary
winding (Ns) of the measuring head. Any remaining flux
is sensed by three toroidal-wound ring cores located
within the secondary winding volume.
Two of them (N1, N2) are used to sense the DC part of
the remaining flux. N3 senses the AC part.
An oscillator drives the two DC flux-sensing cores into
saturation in opposite directions. The resulting current
peaks are equal in both directions if the remaining DC
flux is zero. If not zero, their difference is proportional
to the residual DC flux. The Zero-flux TM CT has a double
peak detector to find this DC flux. After adding the AC
component (N3), a control loop is set up to generate
the secondary current that makes the flux zero. A power
amplifier provides this current Is to the secondary winding
Ns. The secondary current, which is a scaled image
(1/Ns) of the primary current, is fed to the burden resistor
to convert the signal into a voltage. The signal across
the burden is amplified to make the signal available
for further use. The unique design of the Zero-flux TM CT
system provides high accuracy and stability without the
need for temperature control devices.
Above several kHz, the power amplifier no longer has
active control over its output current, but merely forms
a short circuit. The Zero-flux TM CT still performs as a
wideband current measuring device, but now with the
measuring head as a passive current transformer. The
final bandwidth is only limited by the stray reactance
and capacitance in the head and interconnecting cable.
THe baSiC PrinCiPle
In case of a Zero-flux TM CT with current output, the
secondary current is the output, omitting in that case the
burden resistor and precision amplifier.
If the core saturates due to primary overload, the zero
flux condition is lost, and a search cycle is started
automatically. This means the secondary current is swept
between the minus and plus current limits in a slow
triangle until zero flux is detected, and normal tracking
continues. The same happens when the auxiliary power
is switched-on with primary current present.
the burDen resistor
In view of required measurement precision a four-wire
resistor is the best. The power dissipation is kept very
low, because the voltage drop across the resistor (usually
0.5V at rated current) is low. The thermal stability of the
burden resistor, under normal load conditions, is ensured
even over the long time.
the Precision amPlifier
The precision amplifier is a very stable differential
amplifier, which delivers a highly accurate output
voltage, proportional with the secondary current through
the burden resistor. To ensure that the gain factor remains
constant, the temperature coefficients of the gain-setting
resistors are matched (TC tracking). The offset error
is minimized by careful selection of the operational
amplifier and fine-tuned during adjustment. The gain,
usually 20x, is factory adjusted in order to compensate
for tolerances in burden and gain-setting resistors. The
output usually delivers 10V at the rated current and may
be loaded by up to 5mA.

The Zero-flux TM CT specifies the maximum waveform peak current, rather than the maximum rms-current, as done for the
direct current input of the Yokogawa power meters. For example to measure 1000Arms with a Zero-flux TM CT you need a
type suitable for 1400Apk, which is the peak value of the sinusoidal current.
Currents having high crest factors also can be measured properly, as long as the waveform “fits” within the peak current
capabilities of the Zero-flux TM CT.
This means you can measure currents up to 280Arms having a crest factor of 5.
