Power Quality for Data Centre

Modern Data Centers of varying sizes and types are constructed and operated at a “Mission Critical Environment” level of criticality to meet business objectives. The reliability and availability of an Enterprise Data Center are expected to be no less than 99.99%. Research programs have established that the quality of stable and reliable power sourcing and distribution design is essential in maintaining the power system’s reliability and availability for electronic loads.

This article discusses the general requirements for power sourcing and distribution systems for electronic loads. It also includes a typical cause-effect analysis and proposes solutions to common power quality issues. 

Why is Power Quality Important to Data Centers?

Power Quality Threshold Limits for Data Center

Regular monitoring and assessment of power quality are crucial for a data centre, as they are necessary for operational and change-management requirements. Periodic assessment of power quality is also essential to troubleshoot power-related interruptions, abnormal system behaviour, the addition of new electronic equipment, or developing a baseline.

Solutions to Power Quality related disruptions.

The reliability and availability of data centres depend on the quality of the power supply. To ensure optimal performance and energy efficiency, the key performance indexes must be kept within acceptable threshold limits. This also contributes to the reliability and availability of the power distribution system.

Collaboration with key stakeholders, such as IT experts, end-users, and utility service providers, is crucial in maintaining the electrical power network. By taking input from all stakeholders, the Facility Team must develop a maintenance regime that adequately addresses any issues related to the power network. This approach ensures that the data center operates optimally, providing a seamless experience for all users.
