EN 50160 Voltage Characteristics in Public Networks

The CEN standard EN 50160 defines the permissible voltage deviations, frequency variations, and harmonic distortions of electrical power supplied to public networks. This service ensures compliance with this standard by testing the quality of electricity in distribution systems within the built environment, particularly focusing on lighting and electrical systems. This is crucial for maintaining reliability, safety, and efficiency in infrastructure.

The standard applies to all public low-voltage (

The testing process involves measuring various parameters such as voltage magnitude, frequency, and harmonic content at multiple points along the distribution network. These measurements are taken under both nominal operating conditions and during transient events like switching operations or faults. The data collected is analyzed to determine compliance with EN 50160 limits.

The apparatus used for this testing includes high-precision voltage and current sensors, power quality analyzers, and data loggers capable of capturing detailed records over extended periods. The test specimens are typically the electrical circuits and components within public lighting systems, including street lamps, traffic lights, and other infrastructure installations.

Acceptance criteria for EN 50160 compliance include ensuring that voltage variations do not exceed ±6% from nominal values at any point in the network, frequency deviations should be limited to ±0.2 Hz around the nominal value, and harmonic distortion levels must remain below a specified threshold (typically 5%). Failure to meet these criteria can lead to equipment malfunction, increased energy consumption, and potential safety hazards.
