Medical instrumentation plays a pivotal role in patient care, diagnosis, and treatment. Among the crucial components powering these devices are miniature voltage transformers. These devices facilitate accurate voltage measurement, isolation, and signal conditioning, ensuring the reliability and safety of medical equipment. This article will explore the role of miniature voltage transformers in various medical applications, including patient monitoring systems, diagnostic equipment, and imaging devices.

Proper specification: Carefully select the voltage transformer based on the specific application requirements, such as the voltage level, frequency, accuracy class, and burden capacity. Ensure that the transformer is capable of handling the expected voltage levels and current loads.

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.

Voltage transformer - according to the principle of electromagnetic induction type and capacitance type two categories. According to the purpose, voltage transformers are divided into two categories: measurement and protection.

A: The main functions of the transformer are: ① used to insulate the secondary equipment such as instruments and relays from the main circuit. ② It is used to expand the application range of instruments, electrical appliances and other secondary equipment. Voltage transformer installation: ① pay attention to the secondary side do not short circuit. ② One end of the secondary side must be grounded. ③ Pay attention to the installation of the terminal polarity current transformer: ① Do not open the secondary side. ② One end of the secondary side must be grounded. ③ Pay attention to terminal polarity

A transformer ​is a device that converts voltage or current proportionally. The function of the transformer is to convert high voltage or high current into standard low voltage (100V) or standard low current (5A or 1A, both referring to the rated value), so as to achieve the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment.

When we open the power distribution cabinet, we can see that there are many current transformers in it. Some power distribution cabinets have only one, and some even have five or six. In fact, they all induce current signals from the bus, but the measured currents have different effects. So what role do they all play in the power distribution cabinet?

The wiring of the current transformer should follow the series principle: that is, the primary winding should be connected in series with the circuit under test, while the secondary winding should be connected in series with all instrument loads.
