How To Determine The Right Current Measurement Technique? - Alltronix

All kinds of power electronics systems like UPS
systems, welding systems, traction converters,
and frequency converters need to be controlled
effectively. And for this, it is important that
the current within them can be quickly and
accurately corrected. Current sensors can prove
to be helpful here. These are electromechanical
components that deliver exact real-time
representation of the input and output currents
of a device. The measuring signals are then used
for accurately controlling the power and for
monitoring performance and functionality. You can
opt for HARTING current sensors here that are
based on the Hall effect, which is the
production of a voltage difference across an
electrical conductor, transverse to an electric
current in the conductor, and to an applied
magnetic field perpendicular to the current. You
can get the finest quality HARTING current
sensors at Alltronix, the most reliable HARTING
distributor in Chennai, Mumbai, Delhi, Pune,
Hyderabad, and Bangalore. Here, you can also get
a wide range of HARTING circular connectors,
data connectors, electronic connectors, encoders,
power connectors, heavy duty connectors, modular
rectangular connectors, PCB terminals, and high
speed backplanes.
Current transformers for measurement convert high
currents within a conductor using a fixed ratio
into electrical signals. This helps to provide
reliable input variables

for evaluation units. In this way, you can
accurately measure the power consumption of
decentralized energy plants, monitor the
deviating currents in the outgoing and returning
conductors in frequency converters, and a lot
more. Thus, with the right measurement technique
and equipment, you can achieve precise
measurement results and no-contact measurement
of current. And for this, you need current
sensors for power electronics, and current
transformers for energy measurement and safety
technology. So now, how do you choose the right
current measurement technique for your
particular application? Choosing the right method
for monitoring current in an application is very
important for optimizing its performance. It is
the requirement of the application that will
determine the basic configuration that needs to
be used to implement the current
monitoring. First and foremost, decide whether
you need to use a direct or indirect measurement
technique. There are certain questions that can
determine your implementation choice and
ultimately help to drive device selection. These
questions are What is the common-mode voltage
that is to be measured? What is the current
range to be measured? Will the measurement be on
the high or on the low side? Is the current
unidirectional or bidirectional? How will the
current value be utilized? The next decision to
be made in terms of selecting the device revolves
around the question What is the next link in
the signal conditioning chain? Many application
requirements can help to determine the best
current shunt monitor for any system
implementation. The most important concerns here
are the required accuracy and maximizing the
accuracy. Thus, many alternatives exist for
monitoring current in systems, which is why it
is very important to choose the correct method to
monitor current in your particular application,
so that its performance can be optimized.
Understand what your application requires, and
then determine the basic configuration to use
for implementing your currentmonitoring. For
