SATEC PM135 Safeguards Public Electric Vehicle Charging Stations

Publish by Admin Web on 24 December 2023

Public electric vehicle (EV) charging stations are at the forefront of promoting sustainable transportation. Ensuring the reliability and safety of these charging infrastructures requires adherence to standards, and one critical standard is EN 50160. This standard defines the voltage quality requirements for public electrical power systems. In this article, we delve into the analysis of EN 50160 voltage quality measurements and explore how the SATEC PM135 plays a pivotal role in protecting public EV charging stations.

Understanding EN 50160 Voltage Quality Measurements:

EN 50160 sets the benchmarks for voltage quality parameters in public power systems. It establishes limits and guidelines for various aspects of voltage quality, including voltage variations, frequency, and harmonic distortion. Compliance with EN 50160 is essential to ensure that the power supplied to electric vehicle charging stations meets the required quality standards.

Key Parameters Defined by EN 50160:

  1. Voltage Variations: EN 50160 specifies limits for short-term and long-term voltage variations, ensuring that the voltage remains within acceptable ranges to prevent disruptions or damage to connected equipment.
  2. Frequency Deviations: The standard outlines permissible deviations in power system frequency, addressing variations that may occur due to changes in generation or load conditions.
  3. Harmonic Distortion: EN 50160 defines limits for harmonic distortion in the power system waveform, emphasizing the importance of maintaining a clean and stable electrical supply.
  4. Voltage Unbalance: The standard sets criteria for acceptable levels of voltage unbalance between the phases in a three-phase power system.

Protection with SATEC PM135:

The SATEC PM135 stands out as a reliable solution for public EV charging stations, providing robust protection mechanisms to ensure compliance with EN 50160 standards.

  1. Accurate Monitoring: The PM135 offers accurate and real-time monitoring of voltage variations, frequency deviations, harmonic distortion, and voltage unbalance. This continuous monitoring ensures that the power supplied to EV charging stations adheres to EN 50160 requirements.
  2. Data Logging and Reporting: The PM135 facilitates detailed data logging and reporting capabilities, allowing operators to track and analyze voltage quality over time. This historical data is invaluable for identifying patterns, diagnosing issues, and demonstrating compliance with EN 50160 standards.
  3. Harmonic Analysis and Filtering: SATEC's PM135 excels in harmonic analysis, enabling operators to identify and mitigate harmonic distortions. The meter's advanced filtering capabilities ensure that the power supplied to EV charging stations meets the stringent harmonic requirements of EN 50160.
  4. Alarm and Event Management: The PM135 features alarm and event management systems that provide instant notifications of deviations from EN 50160 standards. This proactive approach allows operators to address issues promptly and maintain the reliability of the charging infrastructure.

In the realm of public electric vehicle charging stations, compliance with EN 50160 voltage quality standards is non-negotiable. The SATEC PM135, with its accurate monitoring, data logging, harmonic analysis, and alarm management capabilities, emerges as a crucial component in safeguarding these charging infrastructures. By ensuring adherence to EN 50160, the PM135 contributes to the reliability, efficiency, and safety of public EV charging stations, promoting the widespread adoption of sustainable transportation.
