EQ Wave

EQ Wave v1 installed with 3-phase voltage, current sensors, and POF fiber link

Purpose and Applications

The EQ Wave is a power system sensor that provides Continuous Point-on-Wave (CPOW) monitoring — uninterrupted, full-resolution waveform capture across all channels — alongside aggregated energy and power metrics (RMS, power, frequency, harmonics). Applications range from energy management and cost optimization through power quality investigation to controls and equipment protection.

• Two-stage measurement isolation with fiber optic networking and TCP data transport
• Fanless operation across -40°C to +70°C in a ruggedized enclosure
• Low-latency measurements: < 8 ms end-to-end with minimal timing variance
• Deterministic, gap-free streaming of waveform and metric data to EQ Watch, EQ Syntropy, and EQ Sight

Primary Use Cases

Power Quality Analysis:

• CPOW capture for complete event investigation
• IEC 61000–4-30 Class S measurements for standards-based reporting
• High-resolution visibility into sags, swells, transients, and distortion
• Harmonic analysis and distortion characterization

Energy Management:

• Continuous energy monitoring and demand profiling
• Load analytics for optimization and forecasting
• Power factor monitoring and correction verification
• Cost allocation and billing verification

Equipment Protection & Diagnostics:

• Signal-level monitoring of voltage and current waveforms
• Threshold-based alerting for out-of-range conditions
• Historical trending for predictive maintenance
• Integration with facility monitoring systems
• Inputs suitable for closed-loop monitoring and future control applications

How It Works

The EQ Wave continuously samples all voltage and current channels at 32 kHz (v1; higher for v2), providing continuous waveform monitoring without gaps or blind spots. CPOW data is streamed and stored as uninterrupted, lossless waveform samples without resampling, trigger dependence, or summarization. Data is streamed over TCP/IP in two formats:

• CPOW: Raw sample data streamed in 2 ms frames for detailed signal-level analysis
• Power monitoring (PMon): Aggregated metrics reported every 10 cycles (50 Hz grids) or 12 cycles (60 Hz grids), providing a consistent 5 Hz update rate for real-time dashboards and trending

The gateway runs EQ Watch, which is storage-agnostic, supporting microSD via USB adapter, NVMe SSD, external SSD, or network-attached storage. With drives up to multiple terabytes, deployments can retain months or even years of continuous waveform history. EQ Syntropy adds physics-informed AI analytics and diagnostics. EQ Sight provides real-time visualization, event monitoring, and interactive investigation.
