Power Quality Monitoring for Utilities and C&I Customers

Q: What is power quality and why does it matter?

Power quality is the degree to which delivered electricity conforms to expected characteristics — steady voltage, clean 60 Hz frequency, and balanced phases. Poor power quality (sags, swells, harmonics, voltage imbalances) damages sensitive equipment, causes production disruptions at C&I facilities, and drives up utility operational costs.

Q: What is Power Quality as a Service (PQaaS)?

PQaaS is Ubicquia's managed offering combining 24/7 distribution transformer monitoring, AI analytics, and expert grid analyst support. Utilities and C&I customers get real-time visibility into power quality issues plus expert guidance on remediation — delivered as a subscription rather than a one-time hardware purchase.

Q: What is voltage sag and swell?

Sag is a short-duration decrease in voltage (typically 10–90% of nominal for a few cycles to seconds); swell is a short-duration increase above nominal. Both are common power quality events triggered by large motor starts, fault clearing, or equipment switching — and both can damage sensitive electronics if repeated.

Q: What are harmonics in power quality?

Harmonics are voltage or current distortions at multiples of the fundamental 60 Hz frequency, typically caused by nonlinear loads (variable-frequency drives, LED lighting, computer power supplies). Excessive harmonics cause transformer heating, capacitor failure, and equipment malfunction — and are increasingly common as electronic loads dominate the grid.

Q: How is real-time transformer monitoring different from a smart meter?

A smart meter reports customer consumption every 15 minutes for billing. Real-time distribution transformer monitoring samples voltage and current thousands of times per second at the transformer, capturing power quality events smart meters can't see — and doing so at a cadence that enables preventive intervention.

Q: How much does poor power quality cost?

The Electric Power Research Institute (EPRI) estimates poor power quality costs U.S. businesses over $145 billion annually — from production losses, equipment damage, and downtime. Commercial and industrial (C&I) customers with sensitive processes (manufacturing, healthcare, data centers) bear a disproportionate share of that cost.

How Ubicquia's Power Quality as a Service (PQaaS) combines 24/7 monitoring, distribution transformer sensors, and AI analytics to prevent outages, reduce OPEX, and protect commercial and industrial operations.

Poor power quality costs U.S. businesses over $145 billion annually, according to the Electric Power Research Institute — and utilities and their commercial and industrial (C&I) customers often lack the visibility to diagnose the root causes. Standard power meters report late and don't have the granularity to pinpoint issues before they become outages or equipment damage.

Ubicquia's Power Quality as a Service (PQaaS) closes that visibility gap. Distribution transformer sensors sample voltage, current, and thermal state thousands of times per second. AI-driven analytics identify sags, swells, harmonics, imbalances, and 20+ other power-quality parameters in real time. A dedicated team of grid analysts backs the platform, translating raw signals into actionable maintenance and diagnostic guidance.

What continuous power quality monitoring delivers

Prevented unplanned outagesReal-time monitoring detects sags, swells, and thermal anomalies before they cascade into equipment failure or service interruption at C&I customer sites.

Faster, targeted diagnosticsImmediately distinguish grid-side issues from customer-side issues, so field crews go straight to the actual fault instead of running diagnostic loops.

Lower OPEX and fewer truck rollsRemote root-cause analysis eliminates the diagnostic truck roll — and the customer-facing complaint resolution that follows.

Expert AI + human analyst supportAdvanced tier customers get AI-driven predictive models plus a team of grid analysts translating power quality events into operational recommendations.

From detection to prevention

The value isn't just faster diagnosis — it's catching issues before they become outages or equipment failures. Voltage anomalies at a manufacturer, harmonics from a variable-frequency drive, thermal drift on a transformer serving a data center — each shows up in the PQaaS data stream weeks before a customer would notice a problem. Utilities that intervene early keep C&I customers running, avoid emergency truck rolls, and extend the operational life of critical distribution equipment.
