Current transducers are a type of device used to measure electrical current by translating the electrical current signal into an analog, proportional output signal. CQ330H is a type of current transformer known as a power-solenoid windings technology current transducer.

CQ330H current transducers are typically utilized in applications where high accuracy and low noise performance are needed. This type of device is able to measure both low and high levels of current with accuracy suitable for professional, laboratory, and industrial applications.

The CQ330H series of current transducers consists of a power core element, an encapsulated windings unit, and a sensing element. The power core element of the CQ330H series is made of special alloy bar that contains stainless-steel wires. The encapsulated windings unit consists of insulated windings, which are responsible for transforming the current passing through the core into an alternate current. The sensing element is composed of integrated electronic components that detect the voltage generated within the windings, and convert it into an electrical signal.

The working principle of the CQ330H current transducers is based on Faraday’s law of electromagnetic induction, which states that a voltage is generated in a conductor which is exposed to a time-varying magnetic field. It utilizes the principle of magnetic induction whereby, the whirling current passing through the power core of the CQ330H will induce a proportional voltage in the windings as well as an electromagnetic field in the surrounding area.

The CQ330H current transducer is designed to be installed in the primary power line with the purpose of measuring the line current. It is usually used in junction boxes, junction cases, or junction modules, and is suitable for a variety of applications such as circuit breakers, transformers, cables, and motors. The CQ330H series is ideal for applications where accuracy, low noise, reliability, and safety are required.

The CQ330H current transducer has a broad range of applications, such as electric vehicle charging, power line monitoring, heavy load current measurement, andharmonic detection. It is also suitable for industrial AC and DC motor control systems, power distribution systems, and embedded AC and DC current detection systems. Furthermore, it is used in applications requiring high accuracy and low noise performance, such as electric power plant condition monitoring, transformer testing, power quality analysis, and remote metering.

In conclusion, the CQ330H current transducer is a powerful device for measuring current in a wide range of applications. Its low-noise, high-accuracy, and reliability makes it an ideal choice for various professional, laboratory, industrial, and commercial applications.
