Description of Current Sense Transformers

Current Sense Transformers are designed to detect and measure current flow in an isolated conductor or a primary winding and produce a proportional alternating current in a secondary winding. The frequency range is 2 Hz to 1 MHz with a current rating of 125 mA to 4000 A. The three types are Invasive, Non-Invasive (Solid Core), and Non-Invasive (Split Core).

Frequently Asked Questions

What is a current sensor with a current transformer?

Current Transformers (C.T.) are used in power supplies to accurately sense and measure current. Their main function is to prevent overcurrent as well as to monitor and control power supply circuits. Utility companies are turning to smart meters to ensure efficient electricity usage.

What is the difference between a current sensor and a current transformer?

Current sensors can detect both AC and DC currents and require an external power supply. Current transformers can only measure AC current and have an output signal of AC 5A or AC 1A, and do not require an external power supply. Ordinary current transformers can only measure AC current.

What is the function of a current sensor?

What is a current sensor? A current sensor detects and measures the current passing through a conductor. It converts the current into a quantifiable output, such as a voltage, current or digital signal, which can be used in a variety of applications such as monitoring, control or protection.
