Micro current transformers have revolutionized the field of electrical current measurement by enabling precise and accurate monitoring of low-level currents. With their ability to step down current levels without sacrificing accuracy, these transformers find extensive use in applications where measuring currents in the microampere range is essential. In this article, we will explore the technical aspects of micro current transformers, their working principles, benefits, and the latest advancements that have elevated their significance in modern electronics.

An encapsulated transformer is a type of transformer that is potted or enclosed in a protective case filled with epoxy resin. This protective casing insulates the transformer from moisture, dust, and other external factors, increasing its lifespan and safety. The encapsulation process also helps to reduce noise and vibration, improving the overall performance of the transformer.

A communication transformer is an essential device used in various communication systems to transfer signals from one circuit to another. It works by using electromagnetic induction to transfer power between two circuits without any direct electrical contact. Communication transformers are designed to operate over a wide range of frequencies and many different signal levels.

An audio transformer is an electrical component that is used to transfer audio signals between different circuits. It works by using electromagnetic induction to transfer power from one circuit to another without any direct electrical connection. The primary and secondary windings of an audio transformer are inductively coupled to each other, which allows for the transfer of the audio signal from one circuit to the other with minimal loss or distortion.

An isolation transformer is a type of transformer that is used to transfer electrical power from one circuit to another while separating the two circuits electrically, preventing direct contact between them. The primary and secondary windings of an isolation transformer are physically separated by insulation, which provides complete galvanic isolation between the two circuits. This isolation prevents electrical noise, voltage surges, and other disturbances from passing between the circuits, making it a critical element in several applications.

power transformers are widely used in several fields. Industrial automation: Power transformers are extensively used in industrial production to supply different voltage levels for various electric equipment such as motors and robots. Medical equipment: Medical devices like X-ray machines, magnetic resonance imaging (MRI) system, electrocardiogram (ECG) machines require a stable power supply, and power transformers play a significant role in providing it. Additionally, portable medical devices also use power transformers for charging.

Split-core iron core current transformers are electrical devices used to measure high voltage currents. They can convert high currents into low current outputs and ensure that the current information is not lost during output. This type of transformer consists of an iron core and several coils, with the iron core able to induce current onto the coils which is then stepped down through the circuit.

The first-ever InnoEX, along with the Hong Kong Electronics Fair (Spring Edition) has opened at the Hong Kong Convention and Exhibition Centre at 12-15/04/2023, attracting a large number of professional visitors to stop, consult and experience.

Motor test measurements usually require ammeters to be equipped with multiple shunt units to solve the problem of ensuring the desired measurement accuracy over a larger measurement range. At this point, the rated voltage drop of all shunt used must match that of the ammeter (e.g. 75 mV).
