Data centers have become the backbone of global connectivity, cloud computing and enterprise operations. Their high-demand environment requires reliable power, and even minor disturbances can lead to significant downtime, data loss or equipment damage. Traditional metering solutions often fall short in capturing transient events, harmonics and voltage anomalies, but the
JEMStar II High Accuracy Revenue Meter addresses these challenges. The JEMStar II delivers precision metering, real-time diagnostics and comprehensive power quality analytics to help data centers improve their operation reliability, energy accountability and it complies with industry standards.
How the JEMStar II Meter Benefits Data Center Applications
- Power Quality Assurance – Data centers require clean and stable power. The JEMStar II Meter’s ability to detect and log voltage sags, swells and transients helps to identify root causes of equipment failures and supports proactive maintenance. The power quality monitoring features also include continuous harmonic, flicker and voltage change event logging, which is critical for ensuring compliance with standards like IEEE 519, designing effective harmonic filters or mitigation systems and maintaining power quality for sensitive IT infrastructure.
- Energy Efficiency and Cost Recovery – Accurate metering ensures that energy usage is correctly billed and monitored. The guaranteed 0.05% accuracy for 10 years of the JEMStar II has contributed to $13,000 annually in unaccounted revenue compared to less accurate meters.
- Real-Time Monitoring and Alerts – With real-time alerts via JSON messages or email, facility managers can respond immediately to anomalies, reducing downtime and improving service continuity. For long-term data retention, the JEMStar II comes equipped with 1 GB to 8 GB of non-volatile memory.
- Compliance and Reporting – The meter’s PQDIF file format and compatibility with third-party analysis tools simplify compliance with standards like IEEE 519 and IEC 61000-4-30 Class A. The JEMStar II also meets cybersecurity standards by being NERC CIPS compliant with audit logs, user access control and encrypted communications.
- Scalability and Integration – Supports totalization across multiple meters, enabling centralized monitoring of distributed systems. Ideal for large-scale data centers with multiple power feeds.
