 THE STANDARD AT 780 NM AND 852 NM WAVELENGTHS
This standard is realized by locking of external cavity diode lasers (ECDL) to the D2 energy transitions of Rb atoms (780 nm) and Cs
atoms (852 nm). The external cavity diode laser (ECDL) was used, which included the anti-reflection coated diode laser AC-SDL-
5410 (spectra diode laser) as an active element with a nominal wavelength 850 nm. The external cavity was formed by the high
reflection faces of the diode laser and diffraction grating (1200 lines/mm) mounted in the Littrow configuration on the piezo
transducer PZT. The diffraction grating allowed detuning of the laser wavelength to the Cs D2 line. By changing of diode laser’s
current with a rate of 1 GHz/mA, the temperature with a rate of 0.3 nm/C, the angle between diode laser and diffraction grating
and also the length of external cavity (0-0.5 µ m); the frequency of ECDL is adjusted to the energy transitions of Rb or Cs atoms.
Fine-tuning was realized by the change of the length of the external cavity by using adjustable PZT voltage. Using the selective
external resonator helps to reduce the diode laser’s spectral band (10-100 MHz) by an amount of (l / L ) ; where, l is the length
2

of the diode laser resonator, L is the length of the external resonator.

The experimental setup for locking of portable ECDL to the D2 energy transition of Rb atoms (λ=780 nm)

The ECDL laser beam passes through the glass cell in which there exists Rb or Cs gases, and then it is reflected back by using a mirror
and detected by photo-detector. The laser frequency is locked to the energy transition of atoms by using an electronic servo system.
The stability of laser frequency, when the frequency is not locked to the energy transition of atoms, changes between 4x10-10 –7x10-9
in the mean time interval of 1-100 s.
After the locking process of the lasers to the energy transition of the atoms, it is measured that the frequency stability values
change in the range of 1x10-12 - 5x10-13. Besides, laser frequency drifts during stabilization on atomic transition was measured to be
less than
± 200 kHz.
These lasers are employed as length standards or for realization of new Cs fountain frequency standards.

The Köster interferometer can measure the length of 1000 mm blocks with an uncertainty less than 100 nm. The refractive index of
the air inside the interferometer can be calculated using the temperature, humidity and pressure values in a semi empiric way with
the Edlen formula. The uncertainty value in the refractive index is in the range of 3.3x10-8. Furthermore, the temperature control
and stabilization is achieved by circulating water through the copper pipes placed over the inner surface of the main body and the
cover.

When the temperature value is set to 20 oC and after the system reaches temperature stabilization, the temperature variation is in
the range of 2 mK as measured using 10 thermistors placed in different places inside the interferometer. Additionally, no drift occurs
in the temperature values for 2 hours.

STANDARD CURRENT TRANSFORMER (ACCURACY < %0.01)
A two stage passive compensated technology
nology is used in the design of standard current transformer
sformer. The standard current
transformer is basically a four wire transformer with three windings and two magnetic cores. The he primary and secondary
windings link both cores, but the tertiary winding only links core 2. The second stage consisting of core 2 and the tertiary
winding, senses the ampere-turn turn difference of the first stage and
under the proper conditions produces a tertiary current that is very
nearly equal to it.
Therefore, the sum of the secondary and tertiary winding currents is
very nearly equal to the ideal secondary current. For the second stage
to produce an accurate correction however, the two stages must have
separate burdens, or the common burden must be very small. The
equivalent circuit of figure illustrates the case in which there are two
separate burdens, designated ZB1 and ZB2. Note that the equivalent
circuit is simply the equivalent circuit of a simple current transformer
with separate burdens transformer (stage 2) embedded in the
equivalent circuit of another simple current transformer
transf (stage 1), and
the primary current of stage 2 is the magnetizing current of stage 1. A solution of the network equations for the equivalent
circuit gives the expression for the transformer ratio, defined as the ratio of the primary current to the sum of the actual
secondary and tertiary currents.
Therefore, the ratio error is approximately equal to minus the product of the ratio errors of the individual stages.

 ELECTRONICALLY COMPENSATED CURRENT TRANSFORMER
The compensated current comparator is a well-known
well known high accurate ratio standard. Construction of a hollow toroid core
prevents almost all external unwanted electromagnetic fields to reach the detector core so that the detector can sense the
unbalanced currents almost without error. Because of this physical advantage, current comparator based ratio standards
have been used in a wide application range.
Several techniques have been developed to achieve error-free
error current
transformations. Recently, the introduction of electronic circuitry is
preferred
eferred because of its simplicity and success in compensation. Use
of electronic circuitry within the current comparator structure showed
that one could design a current transformer with errors not more than
few ppms.
A new compensation technique for laboratory labor type current
comparators has been developed at UME. Similar to others, it has a
detector core C3, a detection winding ND, a hollow toroid core C1 surrounding the detector core, a primary winding NP and a
secondary winding NS. Then, two additional windings
win NC1, NC2 with the same number of windings are wound to inside and
outside of the hollow toroid core, and connected each other in series but inversely. Here, C2 represents a thick magnetic
shield surrounding the detector core and winding. The dashed lineline shown in the figure represents a thick copper shield to
prevent NC1 from the stray fields of primary and secondary currents.
The electronic circuitry is designed as a transconductance amplifier which amplifies the voltage obtained from the detector
winding
ding and converts it into a current. And, it forces this current to the inner and outer compensation windings not only
for compensating the secondary current but also for zeroing the detection voltage, automatically.

 AC CURRENT SHUNT (SQUIRREL CAGE)
Coaxial shunts for precision current measurements at power frequencies are built by UME using a squirrel-cage design
developed by the Mendelejev Institute.
Their extremely symmetrical design and the use of discrete resistors are their typical properties. The purpose of the design
is to minimize the mutual inductance between the output of the shunt and the current path leading to the resistors and
also external current loops.
Double-sided copper-clad boards which are normally used for printed circuits boards are used for building the current
paths and the side walls. They are arranged so that the currents on each side of the boards are equal in magnitude and of
opposite direction. As the boards are thin, the current loop areas are small and thereby the magnetic fields caused by
these loops inside the shunt are also small. The cylindrical symmetry further minimizes these magnetic fields. The
influence from magnetic fields caused by external current loops is minimized by the cylindrical symmetric design and the
sheet-metal housing.
It also enables the type of current paths used in this design by which the resistors are placed far from the possible
unsymmetries at the current input, thereby decreasing the mutual inductance even more.

 THREE PHASE ELECTRONICALLY COMPENSATED ISOLATION
CURRENT TRANSFORMER FOR ELECTRICITY METERS
Electricity meters with interconnected current and voltage circuits are increasingly preferred by the electricity meter
manufacturers for lowering the manufacturing costs and to prevent their misuse for fraud.
Meter manufacturers and operators used to test such meters by directly disconnecting the voltage and current terminals
just before the tests and then connecting them together inside the meter. However, the only testing method for the

introducing isolation voltage and current transformers. Simply, an isolation voltage transformer for each single-phase
electricity meter and a three-phase isolation current transformer for each of three-phase meter.
These transformers should have amplitude and phase errors small enough as not to introduce significant additional errors.
The electronically compensated three-phase isolation current transformers developed by TUBITAK UME are operated well
in a large operating range within the desired 0.05% error condition which is ten times better than the accuracy class of any

 REFERENCE THERMOCOUPLES
Type R, S, Pt/Pd and Au/Pt

R and S type thermocouples are widely used for contact temperature measurement in temperature range from
0 °C up to 1400 °C due to their easy handling, resistivity to mechanical and thermal shocks within wide temperature range
and their high stability. The lower drift and higher stability at high temperatures of the platinum based thermocouples than
the base metal thermocouples (type K, J, N, E, T…) are main reasons why platinum based thermocouples are recommended
for use as the reference thermometer.

In order to improve the quality of temperature measurements in the temperature range from 800 °C to 1500 °C, new kind of
thermocouples have been developed using thermoelements of the pure platinum and palladium. These thermocouples have
shown better characteristics than the standard platinum-thermocouples B, R and S types due to the structure of noble metal
thermoelements. Pt/Pd thermocouples are recommended for use as the reference thermometer in the high temperature
range.
For the temperature range from 0 °C to 1000 °C the Au/Pt type thermocouples are recommended as reference thermocouples.

Reference thermocouples are delivered with calibration certificates.
