How to Choose a Current Transformer For Metering Applications

 



In Industrial and factory settings, it is crucial to measure the total power consumed and the current flow accurately. This is where transformer-rated energy meters come into play, and Current Transformers (CTs) are a vital component of these meters. Unlike energy meters used in homes, CTs are required for Transformer-rated energy meters to measure the electrical energy consumed, especially when the current is above 50A.

Current Transformers are typically used to measure line currents that are beyond the range of conventional analog and digital ammeters.

There are different types of CTs available with various parameters and features. In this blog, we will discuss the factors to consider when choosing a right current transformer for metering.
