Current Transducers

Current transformer applications have been around for more than a century. In the early 1900\'s, current transformers were used in electric motors and generators, initially to provide the switched current signal to a controller, and then later to control the current transformer-based devices that regulated associated power consumption. More recently, current transformers have been applied to test and measurement equipment, and to protect electrical systems by automatically disconnecting overloaded circuits.

The HO 120-NP current transformer is a device used to measure current without having to break the flow of that current. This device has the ability to measure alternating current, direct current, and frequencies from 10 kHz to 10 MHz, making it applicable in a wide range of fields. The HO 120-NP can be used for metering, protection, and control. It is also used for measurements such as phase-to-phase, voltage, frequency, and power.

Design and Functionality

The HO 120-NP consists of a toroidal winding around a ferromagnetic core that is filled with an epoxy resin. This design has the ability to provide accurate measurements that are independent from the load. The core has an opening in the center, which allows the measured current to pass through. This is usually done by passing the conductors near or through the device. The measured current then flows through the HO 120-NP core creating a magnetic field, which is then transformed into an output voltage.

The HO 120-NP has an adjustable secondary winding ratio that allows it to be used for measuring both very low currents and high currents. This feature makes it suitable for applications such as wiring continuity tests, motor current protection, and fault detection. The HO 120-NP is also equipped with an analog output that can be used for voltage or signal readings.

Applications

The HO 120-NP current transformer can be used in a wide range of applications, including metering, control, protection, and fault detection. Metering applications include helping to measure AC or DC voltage, as well as frequency, power, and phase-to-phase. The HO 120-NP can also be used to control electric motors, transform power supplies, and monitor the power consumption of industrial equipment. For protected systems, the HO 120-NP helps to prevent unnecessary overloads and tripping of electrical systems. The device can also be used to detect faults in wiring systems.

Working Principle

The basic working principle of the HO 120-NP current transformer is simple and involves a process of induction. The measured current flows through the central opening of the transformer core; this in turn generates a magnetic field. The induced current then flows through the secondary winding of the transformer; the transformer amplifies the signal and lowers the impedance of the load. The output is then taken off at the secondary winding; this can be in either an analog or digital format.

Advantages

The HO 120-NP current transformer has a wide range of advantages. Its fixed core design ensures that it is independent from the flowing current, providing accurate and reliable measurements. The adjustable secondary winding also ensures that the transformer can be used for measuring both low and high current. Additionally, this device has a high saturation current rating and can be used for both AC and DC applications. Its low power consumption also ensures its economical usage.

Conclusion

The HO 120-NP current transformer is a device used for measuring current without having to break the flow. This device is widely applicable in a range of fields, including current measurements, protection, metering, and control. Its design ensures that it is independent from the flowing current, providing reliable and accurate measurements. The adjustable secondary winding also allows it to be used for both low and high currents. With its low power consumption, the HO 120-NP current transformer is an economical and effective choice for any application.
