​Power system monitoring, protection, and control are critical aspects of ensuring reliable and efficient electricity supply. In this blog post, we will explore the role of miniature voltage transformers in these processes and understand their significance in achieving accurate and isolated voltage measurements for various applications, especially in the field of medical devices.

Miniature voltage transformers play a crucial role in providing accurate and isolated voltage measurements in critical medical applications. These transformers are designed to ensure the safety and reliability of voltage measurements, which are vital for monitoring and diagnosing patients in medical settings. In this article, we will explore the importance of miniature voltage transformers and their use in medical applications.

Isolation transformers are used to provide electrical isolation between two circuits. They have a primary winding and a secondary winding that are electrically separated, which means there is no direct electrical connection between the two windings.

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?
