NextSine – Power Quality as a Service

Rent professional-grade Class S measurement technology. Access live cycle-to-cycle analytics, detect LF-oscillations, and monitor HF-interference up to 25 kHz—all streamed directly to your exclusive data platform. No CAPEX, just pure insights.

The Solution: PQaaS

Stop investing in static hardware. Start subscribing to dynamic insights. Traditional PQAs are often expensive, quickly outdated, and require manual data extraction. With NextSine, you get a scalable fleet of high-end sensors that grow with your grid’s requirements.

• Zero Investment Risk: Low monthly fee instead of high purchasing costs.
• Ultimate Flexibility: Rent more units for specific grid studies or return unneeded devices at any time.
• Always Up-to-Date: Benefit from continuous feature upgrades and cloud-based analysis tools without hardware swaps.

High-End Technical Capabilities

Engineered for Grid Operators and Maintenance Experts. The PQOpen Rail-Mount is more than a „simple“ PQA. It is a high-speed diagnostic tool designed for complex distribution networks and industrial environments.

• IEC 61000-4-30 Class S Accuracy: Reliable, standardized measurements for professional grid assessment. Voltage, Frequency, Harmonic, Interharmonic, Flicker, Events (Dips, Swells) and Current & Power.
• Cycle-to-Cycle Live Streaming: Don’t wait for the download. Analyze dynamic grid behavior with real-time data transmission of every single cycle.
• LF-Oscillation Detection: Specialized in identifying low-frequency oscillations (below 50 Hz) that traditional meters often miss.
• High-Frequency Analysis: Deep-dive into power quality issues with HF-monitoring up to 25 kHz to detect modern switching interference.
• Wide Area Monitoring: Synchronize multiple devices across your infrastructure for a holistic view of your grid’s health.

The Data Platform: Your Live Grid Cockpit

Real-time data meets professional analytics. Every rented device includes access to our exclusive, secure data platform where your measurements are stored and processed live.

• Live Dashboards: Monitor voltage, current, and harmonics from anywhere in the world.
• Advanced Event Analysis: Instantly identify transients, sags, and swells.
• Long-Term Archiving: Compliance-ready storage of your historical data for trend analysis and reporting.
• Feature on Demand: We develop custom features for specific analysis needs.

How It Works

1. On-Board: Choose your subscription plan and number of devices.
2. Connect: Mount on the DIN rail and connect via WiFi/Ethernet. The device automatically links to your platform account.
3. Analyze: View live cycle-to-cycle data immediately. Scale your fleet up or down based on your project needs.

Beyond Standard Monitoring

Feature	Traditional PQA (Purchase Model)	NextSine (As-a-Service)
Financial Model	High CAPEX: Large upfront investment per device; budget-locked for years.	Zero CAPEX: Transparent monthly fee treated as an operational expense (OPEX).
Data Accessibility	Delayed & Manual: Data stored on SD cards; requires on-site visits for manual downloads.	Live & Instant: High-speed streaming directly to your exclusive cloud data platform.
Analysis Depth	Static Snapshots: Limited to 10-minute averages or manual event triggers.	Cycle-to-Cycle Live: Continuous analysis of every single cycle for real-time dynamic insights.
Measurement Range	Standard Focused: Primarily monitors 50/60 Hz; misses high-frequency noise.	LF & HF Detection: Specialized in LF-oscillations (<50 Hz) and HF-analysis up to 25 kHz.
Scalability	Rigid: Expanding your monitoring network requires new capital approval and purchases.	On-Demand: Rent more units for specific grid studies and return them when the job is done.
Lifecycle & Updates	Hardware Obsolescence: Firmware is static; new features require buying new hardware.	Future-Proof: Continuous feature upgrades (e.g., new filters) are rolled out automatically via the cloud.
Maintenance Risk	Self-Managed: You are responsible for repairs, calibration, and replacement of broken units.	All-Inclusive: Hardware support, maintenance, and immediate replacement are included in your service.
Network Visibility	Isolated Points: Difficult to synchronize data from multiple remote locations.	Wide Area Monitoring: A unified, synchronized view of your entire infrastructure in one dashboard.
