    FAQ

    Q1: What is a normal leakage current?
    A1: Normal leakage current varies depending on the type of electrical equipment and its application, but generally, it should be minimal and within safe limits. For most household appliances, a leakage current of up to 0.5 mA is considered acceptable, while for medical devices, the limit can be as low as 10 ”A. In industrial settings, the acceptable range can differ based on specific standards, but values typically range from 0.5 mA to 3.5 mA. Any leakage current significantly above these thresholds may indicate insulation failure or other electrical faults, posing safety risks and necessitating immediate inspection and remediation. Regular testing and monitoring are essential to ensure that leakage currents remain within safe limits to protect both equipment and users.

    Q2: What are the types of leakage current?
    A2: There are several types of leakage current that can occur in electrical systems, each arising from different causes and posing varying risks. Capacitive leakage current is caused by capacitive coupling between live conductors and nearby conductive surfaces, often seen in insulated cables and can increase with voltage. Conductive leakage current results from moisture, dust, or other contaminants that create a conductive path on the surface of insulation materials, leading to unintentional current flow. Inductive leakage current occurs due to electromagnetic induction, where nearby magnetic fields influence current flow in unconnected circuits. Ground leakage current refers to the current that flows through the ground conductor, often resulting from insulation breakdown or equipment faults. Understanding these types is crucial for implementing appropriate safety measures and ensuring the reliable operation of electrical equipment.

    Q3: How to solve leakage current?
    A3: To effectively solve leakage current issues, the first step is to conduct a thorough inspection and testing of the electrical system to identify the source of the leakage. This includes checking for damaged insulation, loose connections, and moisture ingress. Once identified, repair or replace faulty components such as cables, connectors, or insulation materials to eliminate the path for leakage current. Implementing proper grounding techniques can also help divert unwanted current safely away from equipment and users. Additionally, using residual current devices (RCDs) or ground fault circuit interrupters (GFCIs) can provide added protection by quickly disconnecting the circuit when leakage current exceeds safe limits. Regular maintenance and monitoring through periodic testing can help prevent future leakage currents and ensure the safety and reliability of the electrical system.

    Tips: How to maintain your digital leakage current analyzer?

    1. The leakage current test equipment should be used in a well-ventilated, dry environment free from dust and electromagnetic interference. 
    2. If the tester is not used for an extended period, it should be powered on regularly, typically once a month, for at least 30 minutes.
    3. After prolonged operation, such as around 8 hours, the testing device should be turned off for more than 10 minutes to maintain its proper working condition.
    4. Over time, the leakage current tester may experience issues such as poor contact or disconnection, so regular maintenance is necessary.
