Electricity consumption at the industrial scale is always massive. Even if it is a small production, processing or assembly unit, its consumption would be significantly high. There are many kinds of devices and instruments used in industrial power systems. Transformers are one of the critical components of the industrial system that are used for various purposes. It is wrong to assume that these are only meant for power distribution. There are other types as well, like an isolation transformer and an instrument transformer. Current transformers are one of the instrument transformers. These are used to measure high alternating current flowing in industrial-grade applications. These work by lowering the value of high current to a feasible value. If you want to choose current transformer manufacturers, read this comprehensive guide.
Factors to Determine the Right Current Transformer
Assess The Nominal Current
The nominal current of the industrial facility is important as it determines the primary current of the current transformer. Suppose your facility has a nominal AC of 60 A. Then choose the current transformer with 90 A ratings. This buffer is important because you don’t want the transformer to work at its highest capacity.
Type of Application
The transformer manufacturers make current transformers for several applications. It can be used for metering the energy consumption by connecting an ammeter or protecting the electrical infrastructure by transferring the signal to the protective relays.
Accuracy Class
Precision is a crucial technical aspect incorporated by current transformer manufacturers while designing. The accuracy class tells how precisely the instrument is measuring the current levels. Some of the popular classes are 0.2s,0.2,0.5s,0.5,1.0, 3.
Maximum Load
Denoted by Volt-Ampere (VA), the maximum load or burden rating should be stated by the transformer manufacturers.
Safety features
The key safety features include protection against environmental factors, IP ratings for liquid protection and the voltage ratings.
Choosing the Transformer Manufacturers
Beyond the technical aspects, a few things that must be considered about the current transformer manufacturers are:
● Reputation in the industry for supporting diverse industrial applications.
● The range of current transformers, from oil-immersed to dry type, from outdoor to indoor, is versatile.
● They must guide through their voltage class, rated power, accuracy class, and other technical factors.
● They must comply with the Indian and International standards of performance, safety and sustainability.
● Each of their unit must be certified, and ethical practices must be followed by them.
● Their after-sales support must be excellent so that any issues are addressed promptly.
Conclusion
While choosing one from the list of the best current transformer manufacturers, one must be aware of the basic technical aspects and assess the transformer manufacturers closely over the different quality and manufacturing parameters. By choosing a reliable company, you not only get a safe and accurate solution but also save a significant amount on capital invested in the poor quality current transformers.
