How Our Approach Is Different—and Why Our Solution Delivers Better Business Performance

Power Quality Visualized
Unlike other power quality assessments that stop at providing raw data, we go a step further. Our Power Impact Report not only reveals the current state of your power, but also offers actionable solutions that address the financial impacts to your building. We’re more than just data providers—we deliver business solutions tailored to your needs.
Power Quality Matters More Than You Think
Power Standards from Utilities
Electrical utilities deliver voltage within a broad acceptable utility range to account for distribution losses. While these ranges meet regulatory standards (i.e. ANSI and IEEE), they don’t necessarily align with how your building’s systems are designed to perform.
Power Standards from Equipment Manufacturers
Most building systems operate best at a specific voltage, +/- 5 Volts—called the Name Plate Voltage Rating (NPR). This rating is established by the equipment manufacturer through rigorous testing under controlled, optimal power conditions. It represents the voltage at which the equipment is proven to perform safely, efficiently, and reliably. Even small deviations from this target can reduce system performance, efficiency, and lifespan.
How Legend’s SmartGATE Bridges the Gap:
Our SmartGATE system continuously monitors incoming voltage and makes real-time adjustments to keep your building operating within the optimal range.
Risk Zones: How Far Off Is Too Far?
Operating outside the optimal range—even if technically “acceptable”—increases the risk of:
- Equipment malfunctions
- Unplanned downtime
- Premature failure of sensitive electronics
We categorize the risk as follows:
- ✅ Optimal: Within ±5 volts of Name Plate Rating
- ⚠️ Moderate Risk: +10 to +24 or –10 to –14 volts
- 🔴 Severe Risk: +25 volts or –15 volts and beyond
Why It Matters
Prolonged exposure to incorrect voltage—especially outside optimal ranges—accelerates wear and increases inefficiencies. This is a hidden risk most building owners aren’t aware of until it’s too late.
