FAQs

What is a current transformer? A current transformer is an instrument transformer designed to step down high alternating currents in a power system to a lower, measurable value that is safe for operating measuring instruments and protective relays. It electrically isolates the high-voltage primary circuit from the secondary measuring circuit.

How does a current transformer work? A current transformer works on the principle of electromagnetic induction. The alternating current in the primary conductor creates a magnetic field, which induces a proportional current in the secondary winding. The transformation ratio determines the amount by which the current is reduced.

What are the different types of current transformers? The main types include wound type, toroidal (window-type), bar-type, optical current transformers (using the Faraday effect), and Rogowski coils. Each type is suited for specific applications based on required accuracy, physical size, and installation constraints.

Where are current transformers used? They are ubiquitously used in electrical power systems for metering energy consumption for billing, protective relaying to detect and isolate faults, load flow monitoring in industries, and in renewable energy systems like solar and wind farms for inverter monitoring and grid synchronization.

What is the difference between a current transformer and a potential transformer? A current transformer is used to measure electric current, while a potential (or voltage) transformer is used to measure electric voltage. Both are types of instrument transformers but serve fundamentally different measurement purposes in a power system.

Why are current transformers important? They are critically important for the safety, efficiency, and reliability of power systems. They enable the accurate measurement of high currents without direct contact, facilitate protective functions that prevent equipment damage and hazards, and are essential for energy management and billing processes.
