How To Determine The Right Current Measurement Technique?

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 current monitoring.
