A power quality study (PQS) is a comprehensive assessment of electrical systems and facilities to evaluate their quality of electrical power. PQS should always be undertaken by registered electricians, electrical engineers or consultants, as they have the specialised knowledge of the tools and equipment needed to carry out accurate readings for reports and the needs of different electrical systems, in addition to Irish grid connection requirements and industry standards (especially for larger spaces for data centres and industrial warehouses).
Why Are Power Quality Studies Important?
Power quality studies are of particular importance for more complex and/or sensitive systems as they focus on identifying and analysing issues such as, harmonic distortion, voltage and power fluctuations, power factor problems, transients and interruptions, which can affect the longevity and performance of electrical equipment. Having regularly scheduled power quality studies in this capacity, supports energy efficiency goals, and prevents costly downtime or equipment damages.
PQS Compliance Requirements
Likewise, power quality studies are essential for businesses to demonstrate and ensure compliance with national and EU standards, for health and safety and insurance purposes. While these services are not essential for smaller businesses and facilities, they are commonly required by insurers or inspectors for larger sites like warehouses, industrial spaces and data centres, as they have complex electrical infrastructure, continuous operations and have a higher demand on the local power grid. Analysis can also be required by utility providers when new loads are being connected to the local grid, or if power-related problems occur. As larger sites such as data centres and warehouses rely on sensitive and continuously operating electrical systems, and complex equipment including motors and automation systems, studies are crucial for informing the grid connection process, ensuring that any new or upgraded connections are safe, and identifying any issues or possible hazards within the system.
Large Scale Power Quality Studies
Power quality studies for larger spaces like warehouses and data centres will typically take between 2-5 weeks. This is inclusive of time required to set-up equipment, the monitoring period, data collection and comprehensive reports provided to the business following the service. The 1-4 weeks needed for monitoring is due to time required for power quality meter to gather precise data for the system’s voltage, current, frequency, power factor, harmonics, transients, flicker, and voltage imbalances. The temporary meters are typically placed at key points in the electrical distribution system, such as main panels or critical equipment, to consistently monitor conditions without interrupting operations, to provide the most precise and accurate readings in real-time. These meters adhere to international standards and their software is designed for numerous readings and comprehensive data computations.
