How QMU 800 Redefines Grid Reliability with Real-Time Partial Discharge Monitoring

Electrical faults happen every day. But they don’t have to lead to unplanned outages or costly repairs.

At EcoPhi, we believe in solving problems before they even become problems. That’s exactly why we developed the QMU 800—our intelligent merging unit designed to detect early warning signs of failure where it matters most.

Real-Time Partial Discharge Monitoring at 2 MHz

One of the key capabilities of the QMU 800 is its ability to continuously monitor partial discharges in real time—thanks to an ultra-high sampling rate of 2 MHz.

This is not just fast. It’s fast enough to capture the smallest disturbances in insulation that could eventually lead to breakdowns. Early detection means your equipment stays healthier, longer. It’s a powerful step toward predictive maintenance and reduced operational risk.

Why Monitor Partial Discharges?

Partial discharges are localized electrical discharges that don’t completely bridge the gap between conductors. Left unnoticed, they can erode insulation, damage equipment, and ultimately cause failure.

But with the QMU 800, you don’t have to rely on luck or periodic inspections. You get a real-time, always-on view of your system’s health.

The Benefits Speak for Themselves:

⚡ Direct and accurate PD measurement
Follows the internationally recognized IEC 60270 approach to ensure standardized, trusted results.

⚡ Early detection of anomalies
Identify subtle changes in your system before they evolve into costly disruptions or failures.

⚡ Remote, data-driven decision making
Monitor cables and high-voltage equipment from a centralized dashboard. Receive alerts the moment something’s off.

⚡ Always active
With the QMU 800, there’s no sleep-time, no downtime—just continuous monitoring and peace of mind.
