Expand your grid visibility to uncover “hidden” harmonics.
Supraharmonic frequencies threaten the quality of modern power generation. Powerside helps utilities see what’s under the surface to prepare and respond.

Energy efficiency has a side effect: Distortions that are hard to detect.
Distributed energy resources and microgrids. Renewables. Inverters. Switched-mode power supplies. The technologies that power sustainable energy are pushing conducted emissions to the 2 kHz-150 kHz range. It’s a phenomenon called supraharmonics. And a problem we’re helping utilities work through.
Problem
Supraharmonics affect power quality and reliability.
Problems include: overheated capacitors; thermal stress on connected equipment; insulation breakdown on cables; premature power supply failure; misoperation of intelligent electronic devices; lighting control malfunction, tripping of low-voltage residual current devices; and a host of other issues that impact power reliability and performance.
Solution
Powerside’s PQube® 3 sees what other solutions can’t.
You need expanded visibility of your grid not only for reliability reasons — but also to report data for renewable energy capacity. Using our PQube® 3 power analyzer paired with properly designed high accuracy sensors, you can — for the first time — continuously measure and record high-frequency emissions across the 2 kHz-150 kHz range on medium-voltage lines. You can’t get that with traditional instrument transformer technologies that are prone to frequency cut off measurement limitations. What’s more, PQube® 3 automatically emails data and graphs directly to your inbox without the need for special software.

PQube® 3: A cost-effective solution to pinpoint issues and reduce maintenance costs
PQube® 3 is a compact powerful 4Quadrant meter that can be integrated into existing panels or build out as a rugged pole mount system. It gives you a clear look at power grid dynamics and quickly identifies fault locations. It also provides for multi-load analysis of AC and DC. Avoid early equipment failure and disruptions caused by DERs.
Other key highlights:
PQube® 3 offers outstanding secure direct communications — enabling connectivity to a broad range of standard SCADA systems or via Powerside’s own free QubeScan cloud platform for fleet management and trend analytics
PQube® 3 is Fully Class A compliant with Power Quality Measurement Methods (Edition 3 of IEC 61000-4-30), the Information Technology Industry Council (ITIC) curve, and the Institute of Electrical and Electronics Engineers (IEEE) 519 protocols
