What is leakage current IEC 62353

Electricity plays a crucial role in our lives, powering everything from the lights in our homes to the technology we rely on. However, while electricity is essential, it can also pose risks if not properly managed and controlled. One of these risks is leakage current, which is regulated by the IEC 62353 standard. In this article, we will explore what leakage current is, why it is important, and how it is measured.

Understanding leakage current

Leakage current refers to the flow of electric current through an unintended path. It occurs when a small amount of current escapes from the intended circuit and follows an alternative route. This can happen due to various factors such as insulation breakdown, moisture, or manufacturing defects. Leakage current is unwanted because it can lead to electrical hazards, potentially causing injury or damage to equipment.

The significance of IEC 62353

The International Electrotechnical Commission (IEC) has established standards to ensure the safety and effectiveness of electrical medical equipment. IEC 62353 specifically addresses the testing and measurement of leakage current in medical devices. Compliance with this standard is crucial to protect patients and medical personnel from potential harm.

Measuring leakage current

Measuring leakage current is a fundamental part of ensuring the safety of electrical devices. Portable appliance testers (PATs), equipped with specific test leads and probes, are commonly used for this purpose. These testers apply a voltage stimulus to the device and measure the resulting current. By comparing the measured leakag
