What is a Leakage ammeter?

An leakage ammeter (English: leakage current measure) is a device that measures the leakage current from electrical equipment, the so-called leakage current value. Generally, it refers to a clamp meter that can measure a minute current of mA or less. Leakage ammeter overview Leakage current is roughly divided into the following four types. Protective conductor current (ground leakage current) Protected conductor current (ground leakage current) is defined in the IEC 60601-1 standard as "current flowing from the mains component through or across the insulator to the protected ground conductor or functional ground connection line". increase. Touch current (contact current), or enclosure leakage current Touch current (contact current), or enclosure leakage current, is defined in the IEC 60990 standard as "current through the human or animal body when touching one or more accessible parts of an installation or device." increase. Patient leakage current Patient leakage current is defined in the IEC 60601-1 standard as "current flowing from the patient connection through the patient to ground". Patient measured current (medical electrical equipment only) Defined in the IEC 60601-1 standard as "an unintended current flowing between a patient connection through a patient and any other patient connection during normal use".

Application of Leakage ammeter

From general electrical equipment to medical equipment, it is used to determine whether or not it meets the standards stipulated by law. Leakage current has a large effect on the human body, and even if it is weak, it is highly likely to cause death, so it is necessary to measure it accurately. It is also important for quality inspection because it can cause noise in semiconductors in communication equipment.
