Electrical Safety in Low Voltage Distribution Systems up to 1,000V AC and 1,500V DC - Equipment for Testing, Measuring or Monitoring of Protective Measures - Resistance of Earth Connection and Equipotential Bonding
Also Known As:
BS EN IEC 61557-4:2021 is a standard that focuses on the electrical safety in low voltage distribution systems up to 1,000V AC and 1,500V DC. Specifically, it pertains to the equipment used for testing, measuring, or monitoring protective measures related to the resistance of earth connection and equipotential bonding. This standard outlines the requirements that such equipment must meet.
The standard emphasizes the measurement of the resistance of earth conductors, protective earth conductors, and conductors for equipotential bonding. It covers not only the conductors themselves but also their connections and terminals. The equipment is expected to provide an indication of the measured value or the limits of the resistance.
By providing guidelines for the testing and measurement of earth connection and equipotential bonding, this standard helps ensure the safety of low voltage distribution systems. It enables practitioners to assess the effectiveness and reliability of these protective measures, facilitating the identification and resolution of any issues or faults that may undermine electrical safety.
