In the rapidly evolving field of electrical power systems, digitalization has brought about significant advancements in various components. One such component is the current transformer (CT). Traditional CTs have been widely used for measuring and monitoring electrical currents. However, with the advent of digital technology, digital current transformers (DCTs) have emerged as a more advanced and sophisticated alternative. This article explores the various advancements in digital current transformers and their impact on power systems.
In the field of electrical power systems, current transformers (CTs) play a crucial role in measuring and monitoring electrical currents. These devices are widely used in various applications to ensure the safe and efficient operation of power systems. In this technical blog post, we will explore the application of current transformers in the United States.
Different types of voltage transformers include current transformers (CTs) and voltage transformers (VTs).

Usage of current transformers
A transformer is a device that converts voltage or current proportionally. The function of the transformer is to convert high voltage or high current into standard low voltage (100V) or standard low current (5A or 1A, both referring to the rated value), so as to achieve the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment.
How many open current transformers should be installed in the distribution box, do you know?
When we open the power distribution cabinet, we can see that there are many current transformers in it. Some power distribution cabinets have only one, and some even have five or six. In fact, they all induce current signals from the bus, but the measured currents have different effects. So what role do they all play in the power distribution cabinet?
Application of current transformers
The wiring of the current transformer should follow the series principle: that is, the primary winding should be connected in series with the circuit under test, while the secondary winding should be connected in series with all instrument loads.
