EQ Forensics™

When to Use EQ Forensics

EQ Forensics is designed for high-stakes cases where you need defensible answers—when conventional meters, loggers, and reports leave critical questions unresolved, including:

• Recurring blown fuses, tripped breakers, or protection misoperations with no clear explanation
• Sensitive loads such as drives, imaging systems, or robotics behaving unpredictably
• Equipment that fails prematurely or intermittently without a single obvious cause
• Unclear boundaries between utility, facility, and vendor responsibility
• Situations where the cost of guessing wrong is high and evidence matters

If you only need routine compliance snapshots, a conventional PQ study is usually sufficient. EQ Forensics is for the problems that keep coming back, or that nobody has been able to explain with confidence.

Standard Engagement Levels

EQ Forensics is offered as three structured engagement types rather than open-ended consulting.

Snapshot (remote triage)

Focused review of existing data and site information to identify likely causes, evidence gaps, and a recommended measurement plan.

Investigation (onsite plus analysis)

Review existing data from meters, logs, and previous reports to understand what is already known. Then define where and how to measure, which phases and loads to instrument, and how long to capture data. Typical data collection periods range from one to four weeks, depending on the nature of the issue and operating cycles. This may use EQ Wave™, existing metering, or both, depending on the level of visibility required.

Verification (post-fix confirmation)

Targeted measurements to confirm that changes had the intended effect and that no new regressions were introduced.

Each engagement includes a concise executive brief (typically two pages) and a technical appendix, with findings rated using a consistent evidence-level rubric.

A Structured Investigation Process

Each engagement follows a clear, repeatable process.

1. Scoping call

Review symptoms, operating context, existing data, and constraints on access or downtime. Clarify whether EQ Forensics is appropriate or if standard monitoring will suffice.

2. Measurement plan

Review existing data from meters, logs, and previous reports to understand what is already known. Then define where and how to measure, which phases and loads to instrument, and how long to capture data. Typical data collection periods range from one to four weeks, depending on the nature of the issue and operating cycles. This may use EQ Wave™, existing metering, or both, depending on the level of visibility required.

3. Field deployment

Install or configure sensors, verify timing and communications, and collect continuous waveform and contextual data over the agreed period.

• Continuous multi-channel data acquisition at 32 kHz sampling rate
• Exact timing of anomalies and disturbances
• Harmonic structure, transients, inrush, imbalance, flicker, switching artifacts
• System-level correlations with equipment, timing, weather, and loads

4. Analysis and correlation

Process continuous waveform data alongside conventional measurements, correlate with events and operations, and test candidate explanations against electrical behavior and site conditions.

• Pattern recognition and event clustering via EQ Syntropy™
• Anomaly classification and detection
• Correlation of patterns with operating states and external conditions
• Root-cause inference and ranking
• Impact estimation for energy, component stress, and PQ compliance

5. Findings and recommendations

Deliver a written report summarizing what happened, why it happened, the strength of evidence, and recommended corrective or mitigating actions. Where appropriate, recommend a process for ongoing monitoring to validate that conditions remain stable or that corrective actions achieved the intended result. Walk through the findings with your engineers and operators so they understand the reasoning, not just the conclusion.

Deliverables for Engineers, Operators, and Management

EQ Forensics is designed to support internal engineers as well as OEMs, insurers, and regulators who need a defensible record of what was measured and how conclusions were reached. A typical EQ Forensics engagement produces the following.

Clear narrative grounded in measured waveforms

A time-aligned dataset of disturbances, harmonics, imbalance, transients, and load behaviors across all monitored circuits, not just RMS trends or short captures.

Root-cause analysis

Ranked, evidence-backed causes of power quality issues with:

• Quantitative measurement data
• Pattern recognition results from EQ Syntropy™
• Engineering interpretation and site context
• Stated confidence levels for each identified cause

Impact quantification

An estimate of how much the issues cost in:

• Energy waste and inefficiency
• Component wear and accelerated aging
• Downtime risk and reduced reliability margin
• Compliance exposure and performance degradation

Actionable recommendations

Specific interventions that address the root causes, such as:

• Equipment settings and configuration adjustments (VFDs, inverters, generators, UPS systems)
• Power system upgrades or corrections (filtering, VAR compensation, neutral sizing, grounding)
• Load redistribution or circuit modifications
• Identification of upstream or downstream issues outside your control
• Cases where no intervention is warranted and monitoring is sufficient

Pre- and post-verification

Objective measurement so you know the intervention worked.

• Baseline measurements before intervention
• Post-implementation verification
• Quantified improvement metrics
• ROI validation where data supports it

Ongoing monitoring recommendations

Where appropriate, the report includes recommendations for whether ongoing monitoring is warranted, and if so, what should be measured, for how long, and at which locations. Recommendations may include EQ platform components or other approaches, depending on what is most appropriate for the site.

Technical Foundation

EQ Forensics is powered by the integrated EQ Platform:

• EQ Wave™ — Continuous waveform capture
• EQ Syntropy™ — Analytics and pattern recognition engine
• EQ Sight™ — Visualization and reporting

Over time, we are encoding investigative methods and workflows from EQ Forensics into EQ Syntropy, so that customers who choose to can run similar investigations themselves using their own governed data.
